BS 4569:1983

This British Standard describes a test, the result of which is expressed as pass or fail, which is suitable for pile fabrics and simulated fur fabrics, except floor coverings, and is intended solely for determining whether the pile of these fabrics will promote the rapid spread of flame with which it is in transient contact. The method is applicable to raised fabrics if required and to assemblies having a pile on the surface.

IMPORTANT NOTE. The result of this laboratory test relates to the behaviour of the test specimens as supplied under the particular conditions of test, and does not take into consideration the effects of ageing, washing, soiling, etc. that may be encountered during the life of a product. It has to be recognized that this test cannot give a full assessment of fire properties in all situations, for instance a pass result does not guarantee freedom from surface flash after heating e.g. by exposure to radiant heat. NOTE The titles of the publications referred to in this standard are listed on the inside back cover.

Gives the procedure, with results expressed as pass or fail, for determining whether a pile fabric will promote rapid spread of flame in the form of surface flash.
