STANDARD METHOD OF FIRE TESTS FOR THE EVALUATION OF THERMAL BARRIERS

Abstract

This method of fire tests for qualifying a thermal barrier for protecting foam plastic insulation or metal composite materials (MCM), herein referred to as a thermal barrier, is applicable to building construction materials, products, or assemblies intended to be used to protect foam plastic insulation or MCM from direct fire exposure.

The performance of the thermal barrier is evaluated by its ability to limit the temperature rise on its unexposed surface and by the ability of the thermal barrier to remain intact in order to provide protection from ignition of the foam plastic insulation or MCM during a standard fire exposure.

This method of fire tests does not evaluate thermal barriers used in or on upholstered furniture or mattresses.

This standard does not purport to address all safety problems or considerations associated with its use.
