1.1 本标准提供了一个分类系统，用于将厚度为1.5μm至355μm的双向取向聚对苯二甲酸乙二醇酯薄膜和片材的性能制成表格。对于该分类系统，聚对苯二甲酸乙二醇酯薄膜和片材应定义为从对苯二甲酸和乙二醇衍生的材料，并应包含至少90%的聚对苯二甲酸乙二醇酯均聚物，典型熔融温度范围为225℃ °C至250 °C。 本规范不适用于涂层、共挤、着色、着色或金属化薄膜或片材。该分类（根据 D8065/D8065M )旨在最终取代规范 D5047 （参考。 附注3 ). 注1: 电影是用术语定义的 D883 作为标称厚度不超过250µm的薄板的可选术语。 注2: 为了符合规范的原始范围 D5047 该分类还包括厚度不超过355µm的板材。 注3: 强烈建议将该分类系统用于所有新的应用和规范，并且胶片规范应参考规范 D5047 迅速撤回或转换为该分类系统。 1.2 聚对苯二甲酸乙二醇酯材料是热塑性材料，可再加工和回收。本规范允许使用这些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 在所有情况下，如果该分类系统的规定与特定薄膜产品的当前参考ASTM规范相冲突，则应以后者为准（见 附注3 ). 1.4 该分类系统适用于商业产品，因此，对生产薄膜时使用的制造参数没有控制。使用该分类系统开发规范文件的人员应负责识别用于单元分类和后缀要求的关键参数和值。 1.5 单位- 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.6 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4: 没有已知的ISO等效于本标准。 1.7 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。 ====意义和用途====== 4.1 该分类系统的目的是提供一种充分识别聚对苯二甲酸乙二醇酯薄膜和片材的方法，并提供一种通过使用简单的线路调用来指定这些薄膜和片材的方法- out名称。

1.1 This standard provides a classification system for tabulating the properties for biaxially oriented polyethylene terephthalate film and sheeting in thicknesses from 1.5 μm to 355 μm. For this classification system, 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 with a typical melting temperature range of 225 °C to 250 °C. This specification does not apply to coated, coextruded, tinted, pigmented, or metallized film or sheeting. This classification (in accordance with D8065/D8065M ) is intended to eventually replace Specification D5047 (ref. Note 3 ). Note 1: Film is defined in Terminology D883 as an optional term for sheeting having a nominal thickness no greater than 250 µm. Note 2: In order to conform to the original scope of Specification D5047 , this classification also includes sheeting up to and including thicknesses of 355 µm. Note 3: It is strongly recommended that this classification system be used for all new applications and specifications and that the specification of films referencing Specification D5047 be expeditiously withdrawn or converted to this classification system. 1.2 Polyethylene terephthalate materials, being thermoplastic, are reprocessable and recyclable. 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 In all cases where the provisions of this classification system would conflict with a currently referenced ASTM specification for a particular film product, the latter shall take precedence (see Note 3 ). 1.4 This classification system applies to commercial products and, as such, there is no control over the manufacturing parameters employed in producing the film. It shall be the responsibility of those developing the specification documents utilizing this classification system to identify the critical parameters and values to be used for the cell classifications and suffix requirements. 1.5 Units— The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.6 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 4: There is no known ISO equivalent to this standard. 1.7 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. ====== Significance And Use ====== 4.1 The purpose of this classification system is to provide a method of adequately identifying polyethylene terephthlate films and sheeting and to provide a means for specifying these films and sheeting by the use of a simple line call-out designation.
