1.1 This test method establishes a small-scale laboratory screening procedure for comparing the ignition resistance and burning characteristics of materials used in protective clothing where flame resistance is not the primary form of protection provided by the clothing.
1.1.1 It is more appropriate to evaluate materials used in applications where flame resistance is the primary form of protection provided by the clothing by other flammability test methods. This test method shall not be used to evaluate materials where flame resistance is the primary form of protection offered by the protective clothing.
1.1.2 This test method provides a means for comparing ease of ignition and burning behavior of materials which include plastic or elastomeric films, coated fabrics, flexible laminates, multilayer-material systems, or other protective clothing materials that are not designated for offering flame resistance as their primary form of protection.
1.2 This test method measures and describes the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products, or assemblies under actual fire conditions.
1.3 The values stated in SI units or other units shall be regarded separately. The values stated in each system may not be exact equivalents; therefore, each system must be used independently, without combining values.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
