The quality declarations to be issued will be denoted as KOMO attest-with-product certificate. Requirements and methods of determination related to the Building Decree are listed in Chapter 3. Chapters 4 up to and including 10 contain requirements not related to the Building Decree. The certification bodies lay down additional requirements together with the requirements laid down in this assessment directive, in the sense of general procedure requirements of certification and attestation, as laid down in the certification and/or attestation regulations of the relevant body. The technical area covered by this AD includes: E6 Doors, windows, shutters, blinds, gates with window frames, for all applications and concerning all wooden constructions. This assessment directive replaces AD 0803 Wooden eterior doors, dated , including amendment sheet dated The quality declarations that have been issued on the basis of that assessment directive keep their validity until Subject and area of application This assessment directive and the quality declarations relate to wooden eterior doors, to be applied in user functions as described in the Building Decree. The wooden eterior doors may, among other things, be applied in frames as referred to in AD If necessary, the application area will be further described in the quality declaration, including any limitations and/or application conditions. A wooden eterior door is understood to be: a. a wooden door separating the interior climate of a construction from its eterior climate, and of which the most important objective is the passing through of pedestrians, and to which BD Article 4.32 does not apply. b. a wooden door for other user functions (including garage doors (total surface area < 6.25 m 2 ), shed doors, etc), installed in a frame, for application in a separation construction, whereby BD Articles 3.2, 3.3, 3.4, 5.3 and 5.4 do not apply. This means that the eterior door forms a part of the isolated shell or lies completely outside of this. The doors referred to under a and b are fully processed. In this AD, wooden eterior doors are classified in 3 concepts, i.e.: I Basic product II Construction phase durable product III Industrial end product Classification of eterior door types The following are distinguished: single doors, double doors, and doors that are composed of top and bottom doors. The following classification is used: a. solid wooden doors, composed of stiles and lintels, whether or not provided with one or more light openings and/or with sandwich and/or solid wooden panels; b. flat doors, either completely or for the major part as assembled constructions; c. plywood doors, for the major part composed of veneer, whether or not provided with a light opening and whether or not provided with a special finishing layer.

For the adhesives to be applied, please refer to Section Sealing of cross-cut ends All cross-cut ends that are eposed directly to the outdoor climate during the user phase and/or eecution phase have to be protected against water penetration. To achieve this, the coating system used by the manufacturer is to be tested on the water permeability requirements according to SKH Publication and the whole door must pass the capillary seams test according to Section If it is not demonstrated that the system meets the requirements, the cross-cut ends are to be sealed using a product, which, according to the basis for assessment for sealers for the timber

20 Wooden eterior doors Page 20 of 55 industry (SKH Publication 04-01), has been demonstrated to be suitable for this application. Sealing of cross-cut ends of timber is defined as follows: The treatment of the cross-sections of timber (including edge covers, glass openings, letter-bo slots, key holes, nosing sills) or the edges of sheet material (including the edges of panels, etc) to protect the material against the penetration of moisture. 5.7 Repairs Small irregularities in timber are to be filled with a repair agent or filler that complies with the requirements as stated in section Refer to SKH Publication for permitted products. For the permitted small irregularities, refer to the Appendi General Quality Requirements for Frame Timber, Window Timber and Door Timber in SKH Publication No repairs are allowed on those faces that will be permanently visible when using a transparent finish. Repairs are however allowed in rebates that are not visible. 5.8 Milling in/milling around To determine the location of hinges and the hole for the door handle (unless otherwise agreed upon), please refer to Figures 1 and 2 of Appendices 1 and 2. For the milling in of burglary-resistant locks and hinges, please refer to the SKH Publication and the processing instructions of the manufacturer/suppliers of these products. The position of the millings-in is indicated in mm (+/- 1 mm). On the closing side, doors are superficially planed towards the stop edge. The angle of planing is to be 3 o ± 0.5 o from a door width of 600 mm; in case of narrower doors, the angle of planing is 4.5 o ± 0.5 o. 5.9 Glazing Glazing of doors must be in accordance with NEN-EN and NEN-EN-ISO 14439; only glazing from the inside is permitted. Note that the glass plus one-sided sealing must fall within the rebate depth. Window panes are to be glazed according to the performance requirements of the NEN Letter-bo slots Letter-bo slots or letterboes shall comply with NEN Visual assessment of a door panel After mounting and topcoating, the door panel must comply with SKH Publication Visual Assessment of a Door Panel Supplementary conditions Concept I Primer system The primer system shall comply with the requirements laid down in AD The requirements for the primer system, as included in AD 0814, are considered to be met if the primer system is applied according to the code of practice as included in Appendi 5, or if it meets the performance listed in Appendi 4.

21 Wooden eterior doors Page 21 of Glazing of assembled flat doors To prevent penetration by water or the capillary effect to the door panel during the construction phase, assembled flat doors are glazed e factory by or under responsibility of the certificate holder. Assembled flat doors that are demonstrably construction-phase proof can be glazed on the building site under responsibility of the door manufacturer. A flat door is demonstrably construction-phase proof if after 24 cycles, according to the accellerated weathering test in Section (rather than the 6 cycles described in Section 9.1.5), no capillary seams are observed from the glass opening Protection at the building site of assembled flat doors Protection at the building site, by means of processing instructions, is to be realised in consultation with the client Supplementary conditions Concept II Undercoat system The wooden eterior doors have to be provided with an undercoat system. The undercoat system shall comply with the requirements laid down in AD The requirements for the primer system, as included in AD 0817, are considered to be met if the primer system is applied according to the code of practice as included in Appendi 5, or if it meets the performance listed in Appendi Glazing of assembled flat doors To prevent penetration by water or the capillary effect to the door panel during the construction phase, assembled flat doors are glazed e factory by or under responsibility of the certificate holder.
