Fire performance of external cladding systems - Part 1 - Test method for non-loadbearing external ..

Summary

This British Standard describes a method of assessing the behaviour of non-loadbearing external cladding systems, rainscreen overcladding systems and external wall insulation systems when applied to the face of a building and exposed to an external fire under controlled conditions. The fire exposure is representative of an external fire source or a fully developed ( post-flashover ) fire in a room, venting through an opening such as a window aperture that exposes the cladding to the effects of external flames.

This British Standard does not cover the performance of glazed window openings or the detailing at such openings which are covered by separate tests. This British Standard does not apply to curtain walling systems or systems that include glass panels, the fire testing of which will be covered by further parts of this standard.
