1.1本试验方法涵盖非金属垫片材料柔韧性的测定。其设计用于测试从成品板材或垫片上切下的样本，供商业使用。通常归类为橡胶化合物的材料不包括在内，因为它们包含在分类中 D2000 . 1.2以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。 1.3 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和健康实践，并确定监管限制的适用性。 ====意义和用途====== 本试验方法旨在测量非金属垫片材料承受搬运的能力，如安装切割垫片之前和期间所遇到的。

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 and health practices and determine the applicability of regulatory limitations prior to use. ====== Significance And Use ====== 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.
