Significance and Use
This test method can be used to obtain the ignition loss of a cured reinforced resin sample. This test method can also be used to examine the fiber architecture of pultruded structural shapes.
If only glass fabric or filament is used as the reinforcement of an organic resin that is completely decomposed to volatile materials under the conditions of this test and the small amount of volatiles (water, residual solvent) that are potentially present are ignored, the ignition loss can be considered to be the resin content of the sample.
This test method does not provide a measure of resin content for samples containing reinforcing materials that lose weight under the conditions of the test or containing resins or fillers that do not decompose to volatile materials released by ignition.
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.
