Scope of standard 1.1 This test method covers the determination of the volatiles content, in weight percent of composite material prepregs. This standard focuses on composites with thermosetting resins that tend to lose a few percent of the matrix mass when heated due to loss of both retained water and low molecular weight matrix constituents that volatilize during heating. 1.2 Use of this test method is limited to maximum temperature of circulating air ovens (approximately 300°C). 1.3 Use of this test method is limited to temperatures below which the matrix flows from the reinforcement. 1.4 The values stated in SI units are to be regarded as standard. 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 the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in Section 8. |
