1.1 This test method covers the determination of the ignition loss of cured reinforced resins. This ignition loss can be considered to be the resin content within the limitations of 4.2. 1.2 The values stated in SI units are to be regarded as the standard. 1.3 This standard is used to measure and describe the response of composite material to heat under controlled conditions, but does not by itself incorporate all of the factors required for fire hazard or fire assessments of the composite materials under actual fire conditions. 1.4 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of whoever uses this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Note 1—There is no known ISO equivalent to this standard.
