1.1 本规范涵盖非刚性、无支撑氯乙烯塑料薄膜和片材，其中组合物的树脂部分至少含有90 % 氯乙烯。其余10个 % 可以包括一个或多个与氯乙烯共聚的单体，或由与聚氯乙烯或其共聚物机械共混的其他树脂组成。 1.2 此处覆盖的氯乙烯塑料薄膜和片材的薄膜厚度应为0.075至0.25 mm（3至10 mils），片材的厚度应大于0.25 mm。 薄膜和薄片应包括满足本规范要求所需的稳定剂和增塑剂。本规范涵盖了透明、半透明或不透明的薄膜和薄板，这些薄膜和薄板是普通的、印刷的、压花的或表面处理的。 1.3 以国际单位表示的数值应视为标准值。 1.4 以下安全隐患警告仅适用于试验方法部分，第节 10 本规范中的: 本标准并不旨在解决与其使用相关的所有安全问题（如有）。 本标准的使用者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1: 没有已知的ISO等同于本标准。 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 covers nonrigid, unsupported vinyl chloride plastic film and sheeting in which the resin portion of the composition contains at least 90 % vinyl chloride. The remaining 10 % can include one or more monomers copolymerized with vinyl chloride, or consist of other resins mechanically blended together with poly(vinyl chloride) or copolymers thereof. 1.2 The vinyl chloride plastic film and sheeting covered herein shall be 0.075 to 0.25 mm (3 to 10 mils) in thickness for film and greater than 0.25 mm in thickness for sheeting. The film and sheeting shall include the stabilizers and plasticizers necessary to meet the requirements of this specification. This specification covers transparent, translucent, or opaque film and sheeting that is plain, printed, embossed, or otherwise surface treated. 1.3 The values stated in SI units are to be regarded as the standard. 1.4 The following safety hazards caveat pertains only to the test methods portion, Section 10 , 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. 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.
