1.1 本规范规定了最小厚度为0.794 mm的模压板的材料、尺寸和工艺以及物理和电气性能的要求和测试方法( 1. / 32 英寸。）由规范中定义的PTFE树脂模塑材料制造 D4894 . 1.2 本规范还规定了由成型材料制成的成型基本形状的要求。本规范适用于平行于所施加成型压力方向的尺寸小于等于300 mm（12 in.）的产品，以及垂直于所施加成型压力方向的尺寸大于等于12.7 mm（0.5 in.）的产品。 1.3 以国际单位制表示的数值应视为标准。 1.4 以下预防性警告仅适用于试验方法部分第节 7. ，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。 需要特别注意 13.2 , 13.3 , 13.6 , 13.8 和A1。 注1: 没有已知的ISO等效于本标准。 1.5 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 establishes requirements and methods of test for the material, dimensions, and workmanship, and the physical and electrical properties of molded sheet in minimum thicknesses of 0.794 mm ( 1 / 32 in.) manufactured from PTFE resin molding materials defined in Specification D4894 . 1.2 This specification also establishes requirements for molded basic shapes made from molding materials. This specification is for products 300 mm (12 in.) or less in a dimension parallel to and 12.7 mm (0.5 in.) or greater in the dimension perpendicular to the direction of the applied molding pressure. 1.3 The values stated in SI units are to be regarded as the standard. 1.4 The following precautionary caveat pertains only to the test method portion, Section 7 , 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. Special attention is called to 13.2 , 13.3 , 13.6 , 13.8 , and A1. Note 1: There is no known ISO equivalent to this standard. 1.5 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.
