1.1 本指南确定了用于评估聚四氟乙烯制造的未烧结挤压薄膜或胶带的测试方法。 1.2 以国际单位制表示的数值，详见 IEEE/ASTM SI 10 ，将被视为标准。 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）。本标准的使用者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: 在拉伸性能、比重和介电常数的测量方面，该试验方法等效于ISO 12086-2:2006。这些内容见ISO 12086-2:2006第8.2.2、10.6和8.1.1节。在任何其他测量或章节中，它不等同于ISO 12086-2:2006。 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。

1.1 This guide identifies test methods to use in evaluating unsintered extruded films or tapes manufactured from polytetrafluoroethylene. 1.2 The values stated in SI units as detailed in IEEE/ASTM SI 10 , are to be regarded as standard. 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. Note 1: This test method is equivalent to ISO 12086-2:2006 in the measurement of tensile properties, specific gravity, and dielectric constant. These are in ISO 12086-2:2006, sections 8.2.2, 10.6 and 8.1.1. It is not equivalent to ISO 12086-2:2006 in any other measurement or section. 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.
