1.1 本规范涵盖FEP树脂的熔融加工成型和挤出材料。本规范不包括回收的FEP材料。这些FEP树脂是四氟乙烯和六氟丙烯的共聚物，或含有不超过2的改性FEP树脂 % 按其他含氟单体的重量计。 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。括号中给出的值仅供参考。 注1: 尽管本规范和ISO 12086-1和ISO 12086-2在方法或细节上有所不同，使用其中一种方法获得的数据在技术上是等效的。 1.3 以下预防性警告仅适用于试验方法部分第节 11 ，符合本规范。 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。 1.4 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。

1.1 This specification covers melt processable molding and extrusion materials of FEP resin. This specification does not cover recycled FEP materials. These FEP resins are copolymers of tetrafluoroethylene and hexafluoropropylene or modified FEP resins containing no more than 2 % by weight of other fluoromonomers. 1.2 The values stated in SI units as detailed in IEEE/ASTM SI-10 are to be regarded as the standard. The values given in parentheses are for information only. Note 1: Although this specification and ISO 12086-1 and ISO 12086-2 differ in approach or detail, data obtained using either are technically equivalent. 1.3 The following precautionary caveat pertains only to the test methods portion, Section 11 , of this specification. 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. 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.
