4、otection provided by the clothing by other flammability testmethods.This test method shall not be used to evaluatematerials where flame resistance is the primary form ofprotection offered by the protective clothing.1.1.2 This test method provides a means for comparing easeof ignition and burning beh
5、avior of materials which includeplastic or elastomeric films,coated fabrics,flexible laminates,multilayer-material systems,or other protective clothing mate-rials that are not designated for offering flame resistance astheir primary form of protection.1.2 This test method measures and describes the
6、response ofmaterials,products,or assemblies to heat and flame undercontrolled conditions,but does not by itself incorporate allfactors required for fire hazard or fire risk assessment of thematerials,products,or assemblies under actual fire conditions.1.3 The values stated in SI units or other units
7、 shall beregarded separately.The values stated in each system may notbe exact equivalents;therefore,each system must be usedindependently,without combining values.1.4 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the use
