BS 8414-1:2002

This part of BS 8414 has been produced to provide a test method for assessing the fire performance of:

• non-load-bearing external cladding systems
• rainscreen overcladding systems
• external wall insulation systems at full-scale when applied to the face of a building and exposed to an external fire under controlled conditions.

The fire exposure conditions have been developed to be 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.
