21、by January 2012, and conflicting national standards shall be withdrawn at the latest by January 2012. This document includes Amendment 1, approved by CEN on 2011-05-21.

BS EN 15254-4:2008+A1:2011EN 15254-4:2008+A1:2011 (E)5 1 Scope This European Standard provides guidance and, where appropriate, defines procedures for variations of certain parameters and factors associated with
25、 the design of fire resistant glazed elements which have been tested in accordance with EN 1364-1, and classified according to EN 13501-2. Extended application of fire resistant glazed elements shall be based on test evidence. This standard only applies to vertically installed fire resistant glazed
26、elements. This standard does not apply to doorsets and openable windows according to EN 1634-1. Glass block assemblies and paver units and channel-shaped glass as defined in EN 1051-1 and EN 572-7 are excluded. There is currently insufficient information available to enable rules for extended applic
27、ation to be developed for these products. NOTE Some partition walls use a combination of fire resistant glass, non-translucent and other opaque products. The extended application in this case only covers the glass when it replaces these products see clause 8.2. 2 Normative references The following r

31、rposes of this document the terms and definitions given in EN 357:2004 and EN 13501-2, together with the following apply. 3.1 fire resistant glass !glass product group (see 3.8), i.e. monolithic, multiple layers or insulating glass unit, that when used in a fire resistant glazed assembly, can have i
32、ts performance determined and classified in accordance with EN 13501-2“ NOTE 1 The glass can be classified for the purposes of CE marking according to the glass product group determined by the glass manufacturer and tested as a virtual assembly. Classification of fire resistant glass is a mandated r
33、equirement within the European Community. NOTE 2 The term “insulating” when used as an insulating glass unit according to EN 12791, should not be confused with the term “insulation” used in EN 135012 classification standard for fire resistant glazed element.

34、+A1:2011 (E)6 3.2 glazing system fire resistant glass and glazing materials used in the fire resistance test to glaze the glass into its framing system, e.g. glazing strips, beads and bead fixings, setting blocks, gaskets, sealant (see Figure B.1) 3.3 glazing materials all materials used to glaze th
35、e fire resistant glass into its frame, e.g. glazing strips, beads and bead fixings, setting blocks, gaskets and sealant (see Figure B.1) 3.4 framing system frame profile and fixings to the supporting structure (e.g. wall) (see Figure B.1) 3.5 reference test fire resistance test in accordance with EN
36、 1364-1, on which the extended application is based and the results, which are used as the main source of data for the extended application NOTE 1 This test may also be used as the initial type test to support CE marking of fire resistant glass or as a market application test. NOTE 2 The reference t
37、est provides the main source of data to determine the following: fire performance classification (integrity E, integrity with radiation EW or integrity with insulation EI); maximum pane area and dimensions for the fire resistant glass; maximum dimensions of the fire resistant glazed element for each
38、 type of frame material. The reference test may also provide other data to assist in determining the following: permitted dimensional changes to the framing system; changes to the glazing system. 3.6 overrun time time of fire resistance in minutes beyond the classification time achieved in the refer
39、ence test, which is the subject of the extended application. The overrun time in the reference test only applies to dimensional changes to the glass and the glazed element. It does not apply to changes to the glazing beads, materials and glazing strips 3.7 previously existing test data test data gen
40、erated by fire resistance tests that have been undertaken by an accredited and/or Notified Test Laboratory in accordance with European and/or former and current national standards based on the temperature-time curve identical to the one specified in EN 1363-1 (and defined in ISO 834). Previously exi
41、sting test data is acceptable even though the test may not have been carried out using the plate thermometer. This data can only be used as described in this standard NOTE Previously existing test data is acceptable provided that there has been no change to the product since this data was generated.
42、 3.8 glass product group different fire resistant glasses combined in a group, defined and produced by the same manufacturer and described in their product description together with a complete list of all components used in the assembly NOTE The manufacturers product description should contain all r
43、elevant properties required for CE marking.

It shall be based on the reference test and supported
44、 by previously existing test data where appropriate 3.11 fire performance classification classification of the fire resistant glazed element in accordance with EN 13501-2 with respect to integrity E, radiation W and insulation I NOTE In previously existing test data the fire resistance is given by t
45、ime to failure (not by fire performance classification above) in terms of integrity, integrity and insulation. The test data may also contain information concerning the measurement of radiation. 4 Principles 4.1 General principles Extended application is a prediction of the expected fire resistance
46、of fire resistant glazed elements. It may be based on interpolation between or extrapolation from test data. The fundamental consideration shall be that the fire resistant glazed element after extension would achieve the required fire performance if it were to be tested according to EN 1364-1. The s
47、pecific principles and methodology governing the extended application for fire resistant glazed elements are given in Figure 1. Fire resistant glazed elements function as an integral system in which the individual components (glass panes, glazing materials, frames and frame fixings) are combined in
48、such a way that they are effective in meeting the defined fire resistance criteria. However, in this document fire resistant glazed elements are separately characterised as the glazing system and the framing system (see Figure B.1). 4.2 Use of test evidence 4.2.1 General The applicant for the extend
49、ed application shall either be the “owner” (i.e. sponsor) of all reference test and previously existing test data being submitted for the extension, or have written permission from the owner to use the submitted test evidence. 4.2.2 Use of previously existing test data Previously existing test data may be used to support extended application, for instance to evaluate the influence of a particular component (e.g. glazing material) or aspect of the des
