5 Page 5 of 64 TECHNICAL SCHEDULE FIRE RESISTING PEDESTRIAN TYPE HINGED OR PIVOTED DOOR ASSEMBLIES WITH NON-METALLIC LEAVES FOREWORD This Technical Schedule (TS) forms part of a series of controlled documents which comprise the CERTIFIRE product certification scheme. It has been prepared in accordance with the requirements of BS EN ISO / IEC for product certification bodies. In addition to this Schedule the other controlled documents relevant to CERTIFIRE certification are: TS00 - General Requirements for Certification of Passive Fire Protection Products/Systems CERTIFIRE Quality Manual Certificate(s) of Approval in the CF000 and CAF000 series, together with any appendices Documentation from the manufacturer This CERTIFIRE scheme aims to provide confidence that installed timber fire resisting door assemblies used with the appropriate building hardware, seals and glass and glazing systems will be capable of achieving the designated fire resistance level and also to demonstrate compliance with performance specifications. This document is intended for the certification of fire resisting doors and door assemblies of timber and wood based construction. It has been prepared and agreed by the organisations listed in Annex G and is in accordance with the requirements of BS EN ISO/ IEC Doors and door assemblies of other types of construction are covered by other Technical Schedules Individual components can have a significant influence on the fire resistance of doors and door assemblies. This Technical Schedule (TS) incorporates criteria to help ensure that the doors will provide the necessary fire resistance when correctly fitted with other CERTIFIRE approved components. For application in the UK, and in other jurisdictions which still accept British Standards, certification based upon BS tests will continue to be available against the requirements of this TS as long as regulations permit or until WCL and/or the industry decide to cease certification.

6 Page 6 of 64 1 SCOPE 1.1 This Schedule defines the technical requirements, via testing and appraisal, of fire resisting door assemblies with leaves of essentially non-metallic construction, including, where relevant, those for smoke leakage control. 1.2 This Schedule is intended to cover door assemblies which are designed solely for pedestrian use. It is not intended to cover metal pedestrian doors or industrial type door assemblies which are covered by TS 12 and TS 30 respectively. 1.3 Items of building hardware, intumescent and smoke seals, glazing systems and glass fitted to doors and door assemblies certificated under this TS are required to be CE Marked and/or CERTIFIRE certificated in their own right as specified in the relevant Technical Schedule. 1.4 This Schedule is based on British Standard tests and is designed to help products satisfy UK regulatory requirements and those of other jurisdictions where British Standards are specified or are accepted. 1.5 Tests conducted in accordance with European Standards may also be used to support certification to satisfy UK classifications. This evidence will be used directly to provide a classification. The results will not be translated into times to failure under a British Standard test. 1.6 The Schedule provides for the certification of fire door leaves manufactured by Prime Door Manufacturers (PDMs), fire door blanks manufactured by Blank Manufacturers (BM s) and for the certification of doors manufactured by a PDM and BM and further processed by an approved Licensed Door Processor (LDP) company under the relevant procedures. These procedures are given in Annex B and C. 1.7 The detailed scope of a system appraisal is given in the Certificate of Approval and the Certificate will identify any limitations applying to the use and interchangeability of the individual components.

DEFINITIONS Assessment The evaluation of proposed changes to the tested specimen(s) which will establish that such modifications can, with a reasonable degree of certainty, be considered to give a fire resistance performance equivalent to that required by the Test Standard, when installed in practice. All of the principles herein are for guidance only as they require that an appraiser exercises expert judgement; therefore these changes may only be undertaken by a CERTIFIRE approved assessor Building Hardware Items such as hinges, handles, locks, door coordinators, panic and emergency exit devices, escutcheons, letterplates, kick plates, closing devices, electrical components, wiring, etc., which are, or can be, used in the door assembly. Blank Manufacturers (BM) The manufacturer of a basic timber door blank in an unfinished condition that requires trimming to size and excludes lippings and decorative facings. Composite Leaves Doors with core and internal framing (if used) of non-cellulosic material and fitted with non-metallic faces and edges. Factory Production Control (FPC) The permanent internal control of production exercised by the manufacturer. All the elements, requirements and provisions adopted by the manufacturer shall be documented in a systematic manner in the form of written policies and procedures. This production control system documentation shall ensure a common understanding of quality assurance and enable the achievement of the required product characteristics and the effective operation of the production control system to be checked. (Definition ref. Construction Products Directive) Fire Door Assembly The bringing together and fitting of all the components necessary to provide the entity able to achieve a fire resistance performance against the appropriate test Standard

10 Page 10 of 64 Fire Door Blank A product which forms the principal construction of a fire door leaf but which requires significant further work by an approved Licensed Door Processor to transform it to the finished item. This may typically involve: cutting to size; the application of lippings; the application of cosmetic face veneers; the provision of apertures for glazing. Fire Door Leaf A hinged, sliding or detachable component of a fire resisting door assembly, which provides closure of the internal frame opening. The door leaf is limited in size, configuration and application as identified in the certification provided by the Prime Door Manufacturer. GDC Multi-layered, solid chipboard blank. Licensed Door Processor (LDP) A joinery firm, licensed by CERTIFIRE, which takes specified certificated fire door blank from a BM or certificated fire door from a PDM, and conducts one or more of the following processes on the product: Sizing of blank (blanks only) Lipping of blank Application of cosmetic face Trimming of doors (where permitted by the certification) The cutting of aperture(s) for glazing, air transfer grilles, letterplates, etc. The glazing of apertures The manufacture of door frames, with or without hardware The LDP may additionally install doors. This is not covered by the CERTIFIRE scheme but is covered by FIRAS the requirements which are not included in this document. Pedestrian Door assemblies Door assemblies up to a maximum size of 2.5m by 2.5m or 6.25m 2 and not exceeding a mass of 160 kg which are primarily intended for the passage of, or access by, pedestrians and associated goods. Prime Door Manufacturer (PDM) The manufacturer of a basic timber fire door leaf finished to a condition that includes lippings and facings and which requires only a frame, hardware and intumescent materials. Additionally the door may be manufactured with a glazed aperture. TT Timber door leaf hung in a timber frame without any intumescent sealing materials incorporated in the leaf to frame junction. ITT As TT but with intumescent sealing materials incorporated in the leaf to frame junction. ITM Timber door leaf hung in a metal frame with intumescent sealing materials incorporated in the leaf to frame junction. 4 GENERAL REQUIREMENTS The general requirements for the certification of doors are given in TS00 which should be read in conjunction with this TS.

11 Page 11 of 64 5 CLASSIFICATION 5.1 Certification of hinged and pivoted fire door assemblies in accordance with the requirements of this Schedule is primarily to provide approvals designed to satisfy the current UK classification requirements. 5.2 For an approval to satisfy current UK classifications (as at August 2014) tests shall normally be conducted in accordance with the British Standards referenced in the appropriate clauses below. 5.3 Tests conducted in accordance with European Standards may also be used to support an approval to satisfy current UK classifications. Note that this evidence will be used directly to provide a classification. The results will not be translated into times to failure under a British Standard test. 6 FIRE RESISTANCE TEST REQUIREMENTS 6.1 The general requirements for fire testing are given in TS The submitted test evidence shall be sufficient to cover each configuration in accordance with 6.3 to 6.8 and Table 1. Where glazed vision panels are required to be fitted within the door assembly appropriate test evidence shall be made available. 6.3 Where separating elements are required to be fire resisting from both sides, normally two specimens shall be tested (one from each direction) unless the element is fully symmetrical. However, in some cases it is possible to appraise door assemblies whereby the fire resistance of an asymmetrical door assembly tested in one direction can apply when the fire exposure is from the other direction. 6.4 If the appraisal is possible the rules given in 6.5, 6.6 and Table 1 shall apply. The rationale behind the rules is given in Annex A. 6.5 The rules governing the applicability of tests carried out in one direction to fire exposure from the other direction are given in Table 1 below. They are based on the following assumptions: a) That the door leaves are themselves of symmetrical construction with the exception of the edges e.g. double rebated doors. b) That there is no change in the number of leaves or their mode of operation e.g. single action or double action. c) That the assembly is symmetrical. 6.6 Table 1 below lists the type of door assembly for which rules can be generated and gives the direction in which it should be tested to cover the opposite direction. The separate columns for the integrity and insulation criteria reflect the ability to make different rules for integrity-only doors as opposed to those which are required to satisfy both criteria. A yes means that it is possible to identify the direction of test which covers the opposite direction. A no indicates that it is not possible to identify the direction which will cover the opposite direction.

12 Page 12 of 64 Type of door assembly Hinged or pivoted, timber leaf, timber frame Hinged or pivoted, timber leaf, metal frame (no transom) TABLE 1 Direction to be tested to cover opposite direction Integrity Insulation Opening into furnace Yes Yes Opening into furnace Yes No 6.7 Additionally, the performance of a door assembly can be influenced by the supporting construction into which it was installed during the fire test and, therefore, this shall be considered in accordance with Annex A, Clause A4 of this Schedule. 6.8 It is important that the type, amount and position of intumescent door edge seal is carefully considered since the appraisal will limit interchangeability. The Technical Schedule for intumescent seals, TS35, should be consulted for more detailed information. 7 SMOKE LEAKAGE TEST REQUIREMENTS (OPTIONAL) 7.1 Where fire resisting door assemblies are also intended for use where restricted ambient temperature smoke leakage is also required (i.e. assemblies requiring a suffix S as defined in Approved Document B to the Building Regulations) they may additionally be certified for such use provided they meet the requirements of this section. 7.2 A CERTIFIRE approved smoke seal shall be used. If the scope of certification of the seal covers use with the door in question no further test data is required. If the scope does not cover the application, further testing with the door under evaluation shall be conducted in accordance with The door assembly shall be successfully tested in accordance with the procedures given in CERTIFIRE Technical Schedule TS21 (The Contribution of Edge Seals to the Control of Smoke Leakage via Door Assemblies). The size and arrangement of the test specimen(s) shall be as given in the Schedule contingent upon the design detail being evaluated and subject to CERTIFIRE agreement. The tests shall include smoke leakage (BS 476: Part 31.1 or BS EN ) and opening/closing force measurement. The cyclic test requirements of TS21 shall also be undertaken. 7.4 Single action and double action configurations shall be subject to separate evaluation as shall the seal type used (i.e. wiping or compression). 8 ASSESSMENT OF PRODUCTS The CERTIFIRE assessment report shall determine the scope of acceptability of the door assemblies and will be in line with the direct assessment principles given in Annex A using the available test evidence as given above.

13 Page 13 of 64 9 CERTIFICATE CONTENTS The certificate and its annexes shall identify the product and any variations in the design. It shall also specify the field of application and the basis of the approval together with any limitations on use of the product. The certificate will give: The certificate number The certificate holder s name The fire resistance period Ambient smoke control, where relevant, denoted by suffix S The maximum size of door leaves for the different configurations An example of a certificate is given in Annex D. 10 IDENTIFICATION AND LABELLING 10.1 The Fire Door Leaf shall be provided with a tamper evident label fixed to the door leaf. Note: Fire Door Blanks shall carry no reference to CERTIFIRE or to CERTIFIRE approved products Other forms of individual identification may be permissible, e.g. inkjet printing, QR codes, micro-chipping, etc., at the discretion of CERTIFIRE The label should preferably be fitted on the top edge of the door towards the closing edge. If it is not possible to fit it there it shall be affixed to a vertical edge, normally the hanging edge. It shall not be fitted to the lower edge of the door Double-leaf assemblies require a label on both doors 10.5 Labels are available from CERTIFIRE or via a CERTIFIRE designated authority The label shall be clearly marked so that the scope of certification can be easily established. The labels shall be sequentially numbered. The marking shall include: The CERTIFIRE logo The certificate number A unique serial number* Optionally the manufacturer s or certificate holder s name. Note if the manufacturer s or certificate holder s name is not applied, no other name or reference shall be identified on the label or door The classification code * Where doors are mass produced, serial numbers may apply to batches of identical doors, manufactured on the same day Where door incorporate a factory glazed aperture an additional, non-sequential label shall be applied identifying specifically that this operation has been undertaken at the PDM manufacturing facility. Alternatively, where appropriate, an alternative version of the standard label, with the unique serial number, can be used identifying the presence of factory glazed aperture. This alternative version of the standard label shall only be applied where factory glazing has been undertaken at the PDM manufacturing facility and must not be applied to unglazed doors.

14 Page 14 of The product shall be despatched with a Data Sheet that explains clearly any special provisions needed for the product to provide its rating and shall give clear installation instructions for the door assembly. The contents of the Data Sheet shall be agreed between the manufacturer and CERTIFIRE. The purpose of the Data Sheet is to ensure as far as possible that information is available at the point of installation. This is satisfied by affixing a copy of the Data Sheet to each door. It is recognised, however, that where a number of doors of the same type is supplied from the Prime Door manufacturer or Licensed Door Processor direct to one site, issuing multiple copies of the sheets is both wasteful and unnecessary. In such cases it is permissible for one information sheet to be supplied with each batch/delivery of doors. In addition, for single leaf, single action latched doors of maximum size 926 mm by 2040 mm a simplified information sheet to a specification agreed with WCL may be supplied. In all other cases the full Data Sheet shall be supplied attached to each door The full Data Sheet shall contain the following: The certificate number Identification of any components required to produce the fire resisting assembly but not supplied by the manufacturer e.g. hardware requirements Details of appropriate supporting constructions and fixing methods including sealing requirements Technical support contact details An example of a Data Sheet is given in Annex F. 11 INSTALLATION 11.1 The correct installation of the door assembly or assembly is crucial if the element is to achieve its designed fire performance in the event of a fire. It is therefore strongly recommended that the supplier of the door assembly or assembly takes precautions to ensure that it is installed by a competent person The door assembly shall be fitted strictly in accordance with the installation instructions. 12 AUDIT PROCEDURES 12.1 Audit Fire Test Prime Door Manufacturers (PDM) and Blank Manufacturers (BM) only Each certificated door design shall be subjected to an audit test at 5-yearly intervals or after the manufacture of every 250,000 doors, whichever is the more frequent. Once a certificated door design passes a 250,000 door audit test the audit frequency is reduced to every 350,000 and then 500,000 doors following a successful audit at 350,000 doors, or 5-yearly intervals, whichever is the more frequent. If the certificated door design fails at 350,000 or 500,000, then it reverts back to 250,000 doors manufactured but only does this after a successful re-test of the failure Doors shall be sourced through the manufacturer s normal distribution/stockist outlets where possible Where sourcing by this means is not possible, i.e., if the PDM does not supply through distributors or stockists, doors may be selected at random from the manufacturer s own stock providing there are sufficient numbers from which to select.

15 Page 15 of Where this method is not possible, e.g. for doors made specifically for contract, WCL or the CERTIFIRE approved designated auditing body will either: o o Place orders directly with one of the manufacturer s customers, selected at random. Manufacturers to whom this applies shall provide a list of regular customers to WCL, or Witness manufacture of doors for test The cost of purchase of doors for audit testing and associated costs such as delivery to the test laboratory, will be charged by WCL to the manufacturer at cost Audit tests normally will be conducted on a 926 x 2040 mm, latched, unglazed, singleleaf, single-action door. Where the scope does not extend to this size of door leaf, the maximum width and height permitted shall be tested Two doors may be tested simultaneously either from the same manufacturer or from two different manufacturers Tests shall not be the subject of a formal report as required by the test standard. A short form report containing sufficient information for WCL s purposes shall be produced. A full report is available at additional cost For door leaves supplied without a frame, building hardware or intumescent seals an additional charge will be made. Complete door assemblies may be sourced via an aperture and frame company certificated to process the relevant doors which is the preferred route The door assembly tested shall be to the design certificated and be at a minimum leaf size of 2040 mm by 926 mm (see ) The test shall be conducted in accordance with BS 476: Part 22: 1987 or EN 1634: Part 1 (as appropriate) Factory Surveillance Visits The general requirements for inspection and surveillance of FPC are given in TS Manufacturers, including Licensed Door Processors, shall be subject to an annual FPC surveillance visit by a WCL auditor The manufacturer is responsible for: a. Providing details of their Quality Management System, and in particular if it changes; b. Making available copies of surveillance and reassessment reports from the Certification Body. c. Maintaining the manufacture of certificated products within their Quality Management System scope; d. Supplying a current Quality Management System certificate (where applicable) and scope to WCL The inspection shall be orientated to the production of doors in the same way as inspection and surveillance of FPC for CE marking.

16 Page 16 of The inspection shall be separate from and additional to those conducted by the ISO 9000 certification body (where applicable). If WCL is the ISO 9000 body or is the certification body for Attestation of Conformity for CE marking, the requirements of both will be covered concurrently. (Note: the frequency of surveillance visits required by the Quality Management System and FPC for CE marking will generally be not less than annually.) 12.3 Consequences of Failure It is accepted that door assemblies can fail to reach the required performance due to the failure of other components and this will be taken into account when determining the action necessary as a consequence of a failed fire test Audit test that achieve the required classification period shall considered to be a pass Audit test failures shall be investigated immediately by the manufacturer and WCL and agreed corrective action taken in line with the table below. Result Corrective action Timescale > or = required fire resistance None required. Next audit test due in line with TS10. period 100% to 85% of required fire resistance period <85% of the required fire resistance period The reason for the reduced performance shall be determined, the fault rectified and procedures amended to prevent re-occurrence. Suspension of certification, product recall or a press announcement will be at the discretion of WCL and will relate to the severity and mode of failure. The certification will be suspended until the reason for the performance has been determined. The probable number of defective doors shall be determined and dialogue between the certificate holder and CERTIFIRE initiated in order to discuss notifying the market and to consider a product recall. The product shall be retested and the door specification and manufacturing procedures reviewed. Providing the reason is able to be determined, there is no need for further tests. If there is no obvious reason for the performance, amendments must be made to the certification within 3 months of the test or further testing conducted to maintain the original scope. The scale of the problem and destination of doors likely to be deficient shall be determined within three weeks. Retest(s) must take place within 3 months otherwise certification will be limited or withdrawn. Steps to notify the market and/or to organise a product recall shall take place within two weeks of the retest. Procedure review shall be conducted within 3 months of the original test Note that a single retest after a failed audit fire test may not be sufficient to revalidate the door and a more extensive test programme may be required to revalidate some or all of the previously certificated scope The consequences of deficiencies in the FPC shall normally result in the issue of a non-compliance report and agreed remedial actions dependent on the severity of the non-compliance.

17 Page 17 of Failure to comply with the required actions shall result in withdrawal of certification Licensed Door Processor The LDP premises shall be subject to FPC surveillance by WCL as detailed in Section 12.2 above.

18 Page 18 of 64 Summary ANNEX A Assessment Methods for Fire Resistance Performance This section covers the acceptable construction parameters that may be appraised under the scope of Technical Schedule TS10. It does not consider the appraisal of the door assemblies for purposes other than maintaining the fire resistance performance achieved in a test or tests. Unless otherwise stated in the following text, the construction of the door assembly shall be the same as that tested. The number of leaves and the mode of operation (e.g. hinged or pivoted, single or double action) shall not be changed. All of the principles herein are for guidance only as they require that an appraiser exercises expert judgement; therefore these changes may only be undertaken by a CERTIFIRE approved assessor. All the following assume that the test evidence upon which the judgement is based was successful ; i.e. more than the required classification period has been achieved. While this may not be necessary, approvals based on specimens that failed to achieve their required integrity rating will require the application of careful judgement, based upon substantial experience of fire testing the construction in question. Failed tests can be considered if the failure is not related to the appraised detail. A1. Specific restrictions on materials and construction Construction parameter Latching mode Configuration Overpanels - Flush Overpanels - Transom Meeting Stiles Intumescent Seals Possibility of change A test on an unlatched door may be used to approve doors installed in the latched mode, but not vice versa. For appraisal purposes evidence will also be required on the unlatched doors being tested with a latch installed (of the relevant size and specification), but disengaged. A test on a single action pair of doors may be used to approve single leaf door assemblies. CERTIFIRE may choose to place limitations on the allowable degree of distortion (which will be 15mm) of double door leaves, under test conditions, before applying this guideline. A test on a door assembly with a flush overpanel may be used to approve a door assembly without an overpanel but not vice versa. A test on a door assembly with a rebated-edge overpanel may be used to approve a door assembly with a square-edge overpanel but not vice versa (single-action, double-leaf doors, without a rebated top edge, will require a surface-mounted stop). A test on a door assembly with an overpanel with a transom will not cover an overpanel without transoms, but may be used to approve a door assembly without an overpanel. A test on rebated meeting stiles can be used to approve plain meeting stiles but not vice versa. The substitution of intumescent door edge seals can only be carried out by the application of CERTIFIRE TS11

19 Page 19 of 64 Building Hardware The substitution of building hardware can only be carried out by the application of the assessment methods found within the relevant CERTIFIRE Technical Schedule for that item of hardware, where one exists; otherwise this will be on the basis of expert judgment. Any CE marked latch, lock or hinge, may be used, subject to it being approved for use on timber based door assemblies to the required classification period, and also subject to the specification constraints identified within the Data Sheet. Smoke Seals The substitution of smoke control door edge seals can only be carried out by the application of CERTIFIRE TS21 Cellulosic based door frames General Density Section size Stop size Material MDF door frames cannot be approved for FD30 (or E30) door assemblies without specific test evidence to demonstrate satisfactory performance. Softwood and MDF door frames cannot be approved for FD60 (or E60) door assemblies without specific test evidence to demonstrate satisfactory performance. Timber door frames should not be approved for door assemblies to provide performance in excess of FD60 without specific test evidence to demonstrate satisfactory performance. Cannot use frame of density less than tested (density of softwood and hardwood is defined as the minimum value associated with the species as identified in BS EN 350-2). See note on species below Can be increased and may be reduced subject to expert judgement Can be increased. May be decreased based on expert judgement. For 30 minutes a successful test with MDF or chipboard will permit the use of solid softwood or hardwood (minimum 510 kgm 3 for solid timber), but not vice versa. A successful test on MDF will not permit the use of chipboard or vice versa. For FD60 and above, the type of material shall not change from that tested e.g. timber, MDF, chipboard, etc. Configuration Species Fixings Stop fixing method Cannot change. Ash & Iroko shall be specifically tested for FD60 and above. Expert judgement required. Pins and screws and integral or loose stops are all interchangeable.

20 Page 20 of 64 Door core Material type Number of pieces Density Lippings Jointing Species Fixing method/type Manufacturer Thickness The core type shall not change from that tested (e.g. flaxboard, chipboard, laminated timber, etc.). May increase from that tested providing a joint was tested. Expert judgement required on maximum number of pieces Can be increased (density of timber cores is defined as the minimum value associated with the species as identified in BS EN 350-2). See note on species below. Can increase in size, up to 25 mm, and density. See note on species below. Where lippings are included these shall not be omitted without specific test evidence. Expert judgement required Ash & Iroko shall be specifically tested for FD60 and above. Expert judgement required May be changed providing the same specification of material(s) is used The thickness of the core shall not be reduced by more than 1mm, but may be increased. The door leaf thickness and / or density may be increased provided the total increase in mass is not greater than 25%. Door rails & stiles Material type Jointing method Density Section size Species Fixing method/type The type of material shall not change from that tested e.g. timber, MDF, chipboard, etc. Finger joints are acceptable in place of butt joints but not vice versa. Mortice & tenon and dowel joints may be interchangeable based on expert judgement. As door frame. Can be increased. May be reduced subject to expert judgement. The size identified shall reflect the section size tested, including any trimming required as part of the manufacturing process. As door frame. Expert judgement required.

21 Page 21 of 64 Timber facings Decorative finishes Decorative laminates, PVC and timber veneers up to 2 mm thickness may be added to the faces and edges of timber door leaves. Decorative laminates, PVC and veneers in excess of 2 mm thickness shall be tested as part of the test specimen. For all products tested with decorative laminate faces the only variations possible shall be within similar types and thickness of material (e.g. for colour, pattern, manufacturer). Constructional face (Skins) Constructional face density Constructional face thickness Paint finishes Hardboard, chipboard, HDF or MDF may be substituted with plywood. Hardboard, HDF or MDF may be substituted with chipboard MDF may be substituted with Hardboard and HDF May be increased but not reduced. May be increased but not reduced (any increase in thickness must not result in a reduction in core thickness of more than 1 mm in total). Where the paint finish is not expected to contribute to the fire resistance of the door alternative paints are acceptable and may be added to door leaves or frame products for which unfinished specimens were tested. Where the paint finish contributes to the fire resistance of the door (e.g. intumescent paints) then no change shall be permitted. Adhesives Manufacturer Type May be changed providing the same specification of material(s) is used, e.g. PVA from one manufacturer may be substituted for PVA from another. Shall not be changed e.g. PVA, UF, PUR, etc. Panel doors Material type Density Thickness Panel construction Intumescent content The type of material for each component shall not change from that tested e.g. timber, MDF, chipboard, etc. Can be increased. Ash & Iroko shall be specifically tested for FD60 and above. Can be increased but not reduced. May be substituted with other successfully tested panel constructions Shall only be as tested

May increase the number of panels providing all structural members remain as tested. May decrease the number of panels providing at least the maximum size panel has been tested successfully. A2 Permissible size variations General Doors of sizes different to those of the tested specimens may be permitted within certain limitations but the variations are dependent on the length of time that the performance criteria are satisfied, in conjunction with the relevant associated distortion of the door leaves. a) Door assemblies are able to be approved at sizes smaller than that tested in line with direct application from EN Door assemblies may be approved at sizes larger than that tested in line with direct application from EN , or in accordance with the following principles. The following formula shall only be applied to door assemblies achieving an overrun of performance. Where: t/2 x % overrun = percentage increase in Deflection 2 door leaf dimensions t = Door leaf thickness (metres) Deflection = Maximum recorded deflection during required integrity period (metres). % overrun = Overrun relative to required integrity performance based on 1st mode of failure at door leaf perimeter (i.e. excluding door leaf core burn through, glazing etc.). Number inputted in decimal form (i.e. a 10% overrun should be inputted as 0.10) b) Where the proposed door assemblies are to include the same number of door leaves as the tested specimen, the maximum deflection recorded during the required integrity period should be utilised. c) Where double-leaf evidence is to be utilised for the purposes of assessing to single leaf configurations, it may be necessary to calculate whichever is the greater of the maximum deflection at the head and jambs, or the overall aggregate deflection of the door leaf (i.e. deflection at mid-height relative to head) shall be calculated to establish the maximum deflection shall be used when identifying the maximum recorded deflection. The maximum deflection permitted is 15 mm.

23 Page 23 of 64 A3 A4 A5 d) Where double leaf assemblies with equal leaves are being considered, whichever is the greater of the maximum deflection at the head and jambs, or maximum disproportionate distortion at the meeting stiles leaf to leaf (based on either an equal or unequal leaf test) shall be used when identifying the maximum recorded deflection. e) Where double leaf assemblies with unequal leaves are being considered based on an unequal leaf test, whichever is the greater of the maximum distortion at the head and jambs, or maximum disproportionate distortion at the meeting stiles leaf to leaf shall be used when identifying the maximum recorded deflection. f) Where double leaf assemblies with unequal leaves are being considered based on an equal leaf test, whichever is the greater of the maximum deflection at the head and jambs, or the overall aggregate deflection of the door leaf (i.e. deflection at mid-height of the meeting edges relative to head) shall be used when identifying the maximum recorded deflection. g) The increase for each door leaf may be applied on height or width, or a proportion of both, provided neither dimension is increased by a greater percentage than that calculated for the area. h) In no case, irrespective of the above calculation, shall the door leaf dimensions be increased by more than 500 mm (height) and 250 mm (width). No limitation on area. Asymmetrical door assemblies As EN Standard supporting constructions As EN Glazing Any CERTIFIRE approved glazing system previously tested in a timber door leaf may be substituted in another timber based door leaf assuming that the door leaf into which it is proposed to be fitted has previously been tested with an aperture of the proposed dimensions incorporated (height/width and area) subject to the conditions given in the table below Tested Door Leaf Construction Framed Flaxboard core Acceptable Assessable Constructions Framed flaxboard or framed chipboard core (of equal or higher density), softwood and hardwood lamel core and GDC. Softwood lamels core Hardwood lamels core Framed Chipboard core GDC Joinery type Solid timber Joinery type Particleboard Softwood and hardwood lamel core (of equal or higher density). Hardwood lamel core (of equal or higher density). Framed chipboard or framed flaxboard core (of equal or higher density), softwood and hardwood lamel core and GDC. All GDC, framed flaxboard, framed chipboard, softwood and hardwood lamel cores. Softwood or hardwood of Higher density. Softwood or hardwood. Where either Ash or Iroko is to be used for FD60 and above, this shall be tested specifically. Expert judgement is required for all unrecognised species and these may require supplementary test evidence

24 Page 24 of 64 Glass may be approved for use in timber door assemblies in accordance with CERTIFIRE TS25 and using the principles below: Construction parameter Aperture linings within tubeboard cored leaves Aperture lining within all door leaves Bead dimensions Possibility of change Any system within tubeboard can only be assessed if actually tested in that material, otherwise a timber liner will always be required. The timber liner is to be a minimum 6 mm thick and of a specification at least equal (in terms of material and density) to that of the door leaf core within which the glazing system was originally tested. Where the original glazing system was lined with softwood/hardwood or intumescent material, the proposed system shall also be lined with similar material regardless of the door leaf construction into which it is to be installed. The only exception is where the proposed door leaf has a solid timber core or higher density than the original liner timber material in which case the softwood/hardwood liner may be omitted. Bead parameters will be identified as follows: Aperture size Edge cover The actual size of the hole within the door leaf or panel, including any timber lining, but excluding any intumescent lining, where applicable. Increased sizes are permitted in accordance with TS25, section A.5, or as identified below. Dimension from the top of the bead to the extreme edge of the glass (ignoring any protruding glazing system).

Total area is < 50% of the permissible area calculated using the method identified within TS25, section A5. 2. Door leaf overrun associated with the glazed panel is > 25% of required classification period. 3. Leaf distortion at the leading edge is low, i.e. < 40% of the effective rebate depth. 4. Door leaf tested incorporating the glazed aperture is a minimum 926 x 2040 mm. 5. Glass and glazing system required either formed part of the original tested assembly, or is CERTIFIRE approved to the required size (height, width and area) for use within timber door leaves. 6. Door leaf edge to aperture edge margin shall be a minimum of 150 mm Changes in position are allowable providing the structural members remain as tested and the apertures are at least 90 mm from the edge of the leaf to the aperture (aperture as defined above), unless proven by test. Splayed beads shall not cover the use of square beads, but the opposite may be allowable subject to expert judgement. Bolections may be added to flush beads but not vice versa. Bolection returns shall be included in the minimum bead height/width dimensions where required. Changes are allowable in line with TS25 Alternative glass types are only acceptable if proven with the specific system Mass of alternative glasses to be taken into account Glazing may be provided within door leaves (ONLY FOR FD30) which have not previously included a glazed aperture but the following details shall be taken into account: Overall door leaf distortion during the full test period Interruption of stiles and rails (i.e. not to occur) Up to maximum of 5% of the total leaf area or 0.1 m 2, whichever is less. Not within 200 mm of leaf edge for flush doors Core material to be considered Unless tested, both leaves in a double leaf door assembly shall be glazed similarly. It is acceptable to replace any panels with a CERTIFIRE approved glazing system. Size constraints may apply.

26 Page 26 of 64 ANNEX B Procedure for Fire Door Blank Manufacturers B.1 These procedures detail how components known as fire door blanks are accommodated within the CERTIFIRE system for the approval of timber fire door assemblies. B.2 Fire Door Blank Manufacturers Where a company manufactures or imports blanks and makes them available to CERTIFIRE approved Licensed Door Processors, the company shall, for the purposes of certification, be considered a Prime Door Manufacturer (PDM). It shall be eligible to submit the door design for approval under the CF Series of certificates. Both the company, as the PDM, and the door design shall fully comply with the requirements of TS10 for timber doors. The certificate shall be in the name of the Prime Door Manufacturer. Door blanks, by definition, require further processing in order to transform them into the leaf of a fire resisting door assembly. It is of prime importance that such a component does not reach the open market as a certified door and that any further processing is only carried out by an authorised Licensed Door Processor. The blanks shall be manufactured under a CERTIFIRE approved quality management system which complies with the requirements of TS00. The blank manufacturing site(s) will be subject to general requirements for inspection and surveillance of FPC as identified in Section 12. Blanks shall be subjected to audit testing, sampled at the manufacturing site for the blank. Audit frequency will be as defined in Section 12. The blanks shall carry no reference to CERTIFIRE or to CERTIFIRE approved products. The approved Licensed Door Processor scope of activity as embodied in the CERTIFIRE certificate shall expressly define the blanks able to be processed and in addition the specific processes able to be performed. All intended processes shall be covered within the scope of the company s quality management system. The approved Licensed Door Processor shall fix a label in the CAF series, additionally the LDP shall specifically identify the CF certificate number for the blank used (either on the same label or on a separate label). The PDM shall not supply blanks to the open market with CF series labels fixed. If the approved Licensed Door Processor intends to market the processed door under its own branding, as opposed to that of the PDM, or requires additional scope beyond that permitted in the PDM s certificate, it then becomes, for CERTIFIRE purposes, a Prime Door Manufacturer and is required to comply with the requirements for such and to attach labels in the CF series.
