BS EN 15998 This document specifies the testing methodology to be used for glass products that are claiming fire resistance. The methodology covers type testing as defined in the relevant glass product standard. NOTE This document provides guidance with the declaration of the characteristic, Safety in case of fire – Resistance to fire (for glass for use in a glazed assembly intended specifically for fire resistance) for the CE marking. The same methodology can also be used to determine the performance classification for market applications (see Annex B).The methodology covers all glass product types that may require testing and classification for fire resistance. Fire resistance testing covers end use applications, for example: doors; -一partitions, walls (including curtain walling); 一floors, roofs;一ceilings.According to any of the product standards for glass in building the characteristic“Safety in case of fire – Resistance to fire (for glass for use in a glazed assembly intended specifically for fire resistance)” can be determined and classified in accordance with EN 13501-2. Therefore the testing shall be undertaken on a complete fire resistant glazed assembly. This requires the glass product manufacturer to specify all the details of the glass and glazed assembly to be tested.The glass product manufacturer rarely, if ever, supplies all the components of the glazed assembly. The glazed assembly as tested is therefore known as a“virtual assembly” as it will not exist until all components come together, e.g. on site. When claiming a performance for the essential characteristic“Safety in case of fire一Resistance to fire {for glass for use in a glazed assembly intended specifically for fire resistance)” for the glass product, the glass product manufacturer shall ensure that all details of the tested glazed assembly are given.The data are available in the classification report as detailed in EN 13501-2.
