1.1 本规范涵盖标称厚度为0.025 mm（0.001 in.）的由聚四氟乙烯制成的未烧结、着色、挤压薄膜或胶带至0.51毫米（0.020英寸），哪些是 ≥ 99 % 在引入颜料之前，先在成分中加入纯聚四氟乙烯。 注1: 对于非烧结非着色产品，请参阅规范 D6585 . 1.1.1 目前尚未确定使用回收聚四氟乙烯生产未烧结挤出薄膜或胶带。当商业可用工艺和材料可用时，本规范将进行修订，以包括回收材料。 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。 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2: 尽管本规范和ISO 13000-1（1997）和ISO 13000-2（1997）在方法或细节上有所不同，使用其中任何一种方法获得的与特定特性相关的数据在技术上是等效的。 注3: 本规范旨在作为规范的补充 D6585 ，因为本文所涵盖的材料因其添加剂的不同而差异很大，足以保证一套独立的要求。 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 unsintered, pigmented, extruded films or tapes manufactured from polytetrafluoroethylene, in nominal thicknesses from 0.025 mm (0.001 in.) to 0.51 mm (0.020 in.), which are ≥ 99 % virgin PTFE in composition prior to introducing pigments. Note 1: For unsintered non-pigmented products refer to Specification D6585 . 1.1.1 The use of recycled PTFE for production of unsintered extruded films or tapes has not been identified at this time. When commercial usable processes and materials are available, this specification will be revised to include recycled materials. 1.2 The values stated in SI units are detailed in IEEE/ASTM SI-10 are to be regarded as the standard. The values given in parentheses are for information only. 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 2: Although this specification and ISO 13000-1 (1997) and ISO 13000-2 (1997) differ in approach or detail, data obtained relating to specific properties, using either are technically equivalent. Note 3: This specification is intended to be a complement to Specification D6585 , as the materials covered herein vary significantly enough due to their additives to warrant a stand-alone set of requirements. 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.
