NFPA 275 Standard Method of Fire Tests for the Evaluation of Thermal Barriers Used Over Foam Plastic Insulation
NFPA 275 泡沫塑料热障的评估试验方法标准
1.1 Scope.
1.1.1* This method of fire tests for a thermal barrier for foam plastic insulation (herein referred to as thermal barrier) is applicable to building construction materials, products, or assemblies intended to be used to protect foam plastic insulation from direct fire exposure.
1.1.2 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 during a standard fire exposure.
First edition! Evaluate thermal barriers accurately with fire tests conducted according to NFPA 275.
Developed in response to building industry and public fire safety needs, NFPA 275 Standard Method of Fire Tests for the Evaluation of Thermal Barriers Used Over Foam Plastic Insulation presents a method for evaluating the fire performance of thermal barriers used over foam plastic insulation to reduce the probability of ignition or delay its occurrence.
Intended for reference by model building codes, NFPA 275's requirements address building construction materials, products, or assemblies used to protect foam plastic insulation from direct fire exposure. (Softbound, 9 pages, 2009)</P)< span>
