1.1 这些测试方法涵盖了厚度不超过2.4 mm（95密耳）的用于电绝缘的均质有机聚合物薄膜的测试。 1.2 这些测试方法不一定适用于与涂层、另一种薄膜或其他类型基材（如织物或纸张）组合的薄膜测试。 1.3 以国际单位制表示的数值是标准值。括号中的值仅供参考。 1.4 以下章节介绍了这些程序: 程序 小节 条件作用 6. 和 7. 介电击穿电压和介电强度 21 到 26 可提取物 65 到 70 热封强度 59 到 64 介电常数和损耗因子 42 到 47 电阻法测量 腐蚀金属 38 到 41 取样 5. 收缩 48 到 53 应变消除 13 到 20 表面电阻率 27 到 31 拉伸性能 12 厚 8. 到 11 体积电阻率 32 到 37 吸水率 53 到 58 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: 这些试验方法类似于IEC 60674-2。 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====== 6.1 薄膜的许多电学和物理性质随温度和湿度的变化而显著变化。塑料薄膜的性能变化非常快；因此，在进行测试时，样本需要处于规定的调节环境中。当在不同的环境中进行试验时，请注意这些条件以及暴露在新环境中的时间。

1.1 These test methods cover the testing of homogeneous organic polymer films not over 2.4 mm (95 mils) thick that are to be used for electrical insulation. 1.2 These test methods are not necessarily applicable to testing films in combinations with a coating, another film, or with other types of substrate, such as fabrics or papers. 1.3 The values stated in SI units are the standard. The values in parentheses are provided for information only. 1.4 The procedures appear in the following sections: Procedure Sections Conditioning 6 and 7 Dielectric Breakdown Voltage & Dielectric Strength 21 to 26 Extractables 65 to 70 Heat-Seal Strength 59 to 64 Permittivity and Dissipation Factor 42 to 47 Resistance Method for Measuring the Tendency to Corrode Metals 38 to 41 Sampling 5 Shrinkage 48 to 53 Strain Relief 13 to 20 Surface Resistivity 27 to 31 Tensile Properties 12 Thickness 8 to 11 Volume Resistivity 32 to 37 Water Absorption 53 to 58 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: These test methods are similar to IEC 60674–2. 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 ====== 6.1 Many electrical and physical properties of films vary significantly with changes in temperature and humidity. Properties of thin plastic films can change very rapidly; therefore, the specimen needs to be in the stated conditioning environment when the test is being performed. When the test is performed in a different environment, note these conditions and the time of exposure to this new environment.
