BS 8414-1:2020

This part of BS 8414 provides a test method for determining the fire performance characteristicsof non?loadbearing external cladding systems, rainscreen overcladding systems and external wallinsulation systems when fixed to, and supported by, a masonry substrate and exposed to an externalfire under controlled conditions. The peak fire exposure is intended to be representative of anexternal fire source or a fully developed (post-flashover) fire in a room venting from an aperture thatexposes the cladding to the effects of external flames.
