1.1 本规范涵盖厚度为1.5μm（0.06密耳）至355μm（14.0密耳）的双轴定向聚对苯二甲酸乙二醇酯薄膜和片材的要求。对于本规范，聚对苯二甲酸乙二醇酯薄膜和片材应定义为源自对苯二甲酸和乙二醇的材料，并且应至少包含90 % 聚对苯二甲酸乙二醇酯均聚物。本规范不适用于涂层、共挤、着色、着色或金属化薄膜或片材。 1.2 聚对苯二甲酸乙二醇酯材料是热塑性的，可重复加工和回收。 2. 本规范允许使用聚对苯二甲酸乙二醇酯塑料材料，前提是满足生产商和最终用户的任何特定要求。 1.3 以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。 注1: 目前还没有与本规范等效的ISO。 注2: 薄膜定义为厚度为 ≤ 250微米（0.010英寸）。 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 specification covers requirements for biaxially oriented polyethylene terephthalate film and sheeting in thicknesses from 1.5 μm (0.06 mil) to 355 μm (14.0 mil). For this specification, polyethylene terephthalate film and sheeting shall be defined as the material derived from terephthalic acid and ethylene glycol and shall consist of at least 90 % polyethylene terephthalate homopolymer. This specification does not apply to coated, coextruded, tinted, pigmented, or metallized film or sheeting. 1.2 Polyethylene terephthalate materials, being thermoplastic, are reprocessable and recyclable. 2 This specification allows for the use of those polyethylene terephthalate plastic materials, provided that any specific requirements as governed by the producer and end user are met. 1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only. Note 1: There is no known ISO equivalent to this specification. Note 2: Film is defined as sheeting having a thickness of ≤ 250 microns (0.010 in.). 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.
