2 This Certificate of Approval relates to the fire resistance of Pyrocet glass when used in timber screens and door leaves and also in steel screens and door leaves, for periods of and 90 minutes integrity, as defined in BS 476: Part 22: 1987 subject to the undermentioned conditions. This product is approved on the basis of: i) Initial type testing ii) An appraisal against TS25 iii) Certification of quality management system to ISO 9001: 2000 vi) Inspection and surveillance of factory production control This Certificate of Approval must be read in conjunction with CERTIFIRE Technical Schedule TS25, Fire Resistant Glass, Glazing Systems and materials. This certificate covers Pyrocet Fire Resisting Glass used in the following systems: Timber screens for periods of 30 minutes integrity Steel doors and screens for periods of 30 minutes integrity Steel screens for periods of 60 minutes integrity Steel screens for periods of 90 minutes integrity General Requirements Where the glass is installed in a timber or steel framed screen, the orientation of the screen shall be no more than ±10º from the vertical. There is no restriction to the direction of exposure for the glass i.e. the glass is symmetrical. Orientation may, however, be restricted by the requirements of a non-symmetrical framing system. Where the glass is used in double-glazed units there may be restriction to the direction of exposure, as detailed in the relevant sections of this approval. Pyrocet glass shall not be fitted into partitioning systems such that any part of the glass is higher than 4000mm from finished floor level. The edge cover to each pane shall be as follows: a) all steel systems 15mm maximum and 10mm minimum b) all timber systems at 13mm maximum and 10mm minimum The glazing beads in any timber based system shall have a chamfer of Page 2 of 10 Signed

5 Pyrocet Glass in steel door leaves for periods of 30 minutes integrity 1. CERTIFIRE approved steel doorset 2. Ceramic fibre gasket, 15 mm by 3 mm 3. 6 mm Pyrocet. Glass to be set on calcium silicate setting blocks to determine the correct edge cover For this application the following conditions shall apply: 1. The doorset, including door frame and associated building hardware, should have achieved at least 30 minutes integrity when tested, or subsequently assessed by one of the laboratories approved by CERTIFIRE as acceptable for this purpose, to BS 476: Part 22: If the proposed doorset is to be used in double-leaf configuration, the test or assessment evidence should be applicable to double-leaf configurations. 3. Likewise, if the proposed doorset is to be used in the unlatched configuration, the available evidence should be applicable to unlatched doorsets. 4. The proposed doorset should also have included a glazed aperture or apertures of the intended size, shape, area and number. 5. When used to glaze CERTIFIRE approved doorsets which have smaller apertures than allowed in this certificate, the aperture sizes specified in the doorset certificate shall take precedence.

9 Glass - alternatives The following details show acceptable variations from the standard 6mm thick Pyrocet glass: The glass may be coated with a Versalite coating for periods of 30 and 60 minutes integrity. The glass may be body tinted in the following colours, for 30 and 60 minutes integrity: a) bronze b) blue c) green d) grey The glass may be screen printed or etchlike applied for 30 and 60 minutes integrity. Glazing System/Materials - alternatives Where possible, the above applications describe generic systems that have achieved the relevant period of integrity when tested in conjunction with Pyrocet glass. There are a number of systems available which are also suitable for use with Pyrocet glass, which may not have specific test evidence in conjunction with Pyrocet. These systems are those listed in the CERTIFIRE Product Register as suitable for use with Pyrocet and up to the maximum sizes listed for the specific glazing system. When the glazing system is determined as suitable using this method, and the system shows sizes smaller than allowable by this certificate, the aperture sizes specified in the system certificate shall take precedence.

There are a number of alternative framing systems available which are also suitable for use with Pyrocet glass, which may not have specific test evidence in conjunction with Pyrocet. These systems are those listed in the CERTIFIRE Product Register as suitable for use with modified toughened glass and up to the maximum sizes listed for the specific system. When the framing system is determined as suitable using this method, and the system shows sizes smaller than allowable by this certificate, the aperture sizes specified in the framing system certificate shall take precedence. This approval relates to on going production. Product and/or its immediate packaging is identified with the manufacturer s name, the product name or number, the CERTIFIRE name or name and mark, together with the CERTIFIRE certificate number and application when appropriate.
