1.1 本标准是评估用于电介质应用的导热电气绝缘板材料性能的测试方法汇编。 1.2 这种材料是薄的、顺应性的薄片，通常通过将导热颗粒填料与有机或硅酮粘合剂混合而成。为了增加物理强度，这些材料通常用机织物或非织造布或介电膜加固。 1.3 这些试验方法适用于厚度约为0.02至6 mm的导热板材。 1.4 以国际单位制表示的数值应视为标准值。 注1: 没有与本标准等效的IEC出版物或ISO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。 另请参见 18.1.2 和 19.1.2 . 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====== 4.1 这些测试方法有助于确定导热板电气绝缘是否符合制造商和用户共同制定的规范要求。 4.2 这些测试方法对于质量评估非常有用。试验方法的结果可用于仪器设计。

1.1 This standard is a compilation of test methods for evaluating properties of thermally conductive electrical insulation sheet materials to be used for dielectric applications. 1.2 Such materials are thin, compliant sheets, typically produced by mixing thermally conductive particulate fillers with organic or silicone binders. For added physical strength these materials are often reinforced with a woven or nonwoven fabric or a dielectric film. 1.3 These test methods apply to thermally conductive sheet material ranging from about 0.02 to 6-mm thickness. 1.4 The values stated in SI units are to be regarded as standard. Note 1: There is no IEC publication or ISO standard equivalent to this 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. See also 18.1.2 and 19.1.2 . 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 ====== 4.1 These test methods are useful to determine compliance of thermally conductive sheet electrical insulation with specification requirements established jointly by a producer and a user. 4.2 These test methods have been found useful for quality assessment. Results of the test methods can be useful in apparatus design.
