1.1 本试验方法包括测定固化增强树脂的燃烧损失。该燃烧损失应视为树脂含量在以下限制范围内: 4.2 . 1.2 以国际单位制表示的数值应视为标准。 1.3 本标准用于测量和描述复合材料在受控条件下对热的响应，但其本身并不包括在实际火灾条件下对复合材料进行火灾危险或火灾评估所需的所有因素。 1.4 防火测试本身就很危险。在进行这些测试时，应采取适当的人员和财产保护措施。 1.5 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 注1: 没有已知的ISO等效于本标准。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 本试验方法用于获得固化增强树脂样品的点火损失。 注2: 燃烧增强聚合物复合材料的有机基质的基本概念也被证明是一种有用的方法，可以目视检查某些增强材料的纤维结构或层压板结构。 4.2 如果仅使用玻璃纤维或长丝作为在本试验条件下完全分解为挥发性材料的有机树脂的增强材料，并且忽略了可能存在的少量挥发物（水、残留溶剂），则燃烧损失应视为样品的树脂含量。 4.2.1 对于含有在试验条件下减重的增强材料或含有不分解为燃烧释放的挥发性材料的树脂或填料的样品，本试验方法不提供树脂含量的测量。

1.1 This test method covers the determination of the ignition loss of cured reinforced resins. This ignition loss shall 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 the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Note 1: There is no known ISO equivalent to this standard. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 4.1 This test method is used to obtain the ignition loss of a cured reinforced resin sample. Note 2: The basic concept of burning off of the organic matrix of a reinforced polymer composite has also been shown to be a useful method for enabling a visual examination of the fiber architecture or laminate structure of some reinforcements. 4.2 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 shall be considered to be the resin content of the sample. 4.2.1 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.
