1.1 本试验方法涵盖了非金属垫片材料柔韧性的测定。它设计用于测试从片状物品或成品垫片上切下的试样，以供商业使用。通常归类为橡胶化合物的材料被排除在外，因为它们包含在分类中 D2000 . 1.2 以国际单位制表示的值应被视为标准。括号中给出的值仅供参考。 1.3 本标准并不旨在解决与其使用相关的所有安全问题（如果有的话）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践，并确定监管限制的适用性。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 =====意义和用途====== 4.1 本试验方法旨在测量非金属垫片材料在安装切割垫片之前和期间承受搬运的能力。

1.1 This test method covers the determination of the flexibility of non-metallic gasket materials. It is designed for testing specimens cut from sheet goods or from the gasket in the finished form, as supplied for commercial use. Materials normally classified as rubber compounds are excluded since they are covered in Classification D2000 . 1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.3 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. 1.4 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 designed to measure the ability of non-metallic gasket materials to withstand handling, as would be encountered before and during installation of cut gaskets.
