This European standard provides guidance and, where appropriate, defines procedures for variations
of certain parameters and factors associated with 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 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 application 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.
