1.1 这些试验方法适用于由烯烃聚合物或烯烃聚合物与第节中定义的其他聚合物的混合物制成的柔性闭孔材料 3. . 1.2 这些测试方法仅涵盖测试程序。规范中概述了产品要求 D4819 . 1.3 除非另有明确规定，经买方和供应商之间的协议，所有测试均应按照本标准中规定的测试方法进行。 1.4 以国际单位制表示的数值应视为标准。 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: 本标准和ISO 7214涉及相同的主题，但技术内容不同。 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====== 5.1 测试程序提供了获取数据的标准方法，用于研究和开发、质量控制、规范下的验收和拒收以及特殊目的。 5.2 通过这些试验方法获得的数据适用于特定试验条件下的材料，并且不一定与在其他环境或使用条件下获得的数据相同。

1.1 These test methods apply to flexible closed cell materials made from olefin polymers or blends of olefin polymers with other polymers as defined in Section 3 . 1.2 These test methods cover test procedures only. Product requirements are outlined in Specification D4819 . 1.3 Unless specifically stated otherwise, by agreement between the purchaser and supplier, all tests shall be performed in accordance with the test methods specified in this standard. 1.4 The values stated in SI units are to be regarded as the 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Note 1: This standard and ISO 7214 address the same subject matter, but differ in technical content. 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 ====== 5.1 The test procedures provide a standard method of obtaining data for research and development, quality control, acceptance and rejection under specifications, and special purposes. 5.2 The data obtained by these test methods are applicable to the material under conditions of the particular test and are not necessarily the same as obtained in other environments or use conditions.
