1.1 塑料薄膜耐化学品性的试验方法包括测量薄膜浸入化学品后的重量损失。 注1: 没有已知的ISO等同于本标准。 注2: 根据术语，薄膜定义为标称厚度不大于0.25 mm（0.010 in.）的薄板 D883型 . 1.2 以国际单位表示的数值视为标准值。以其他单位表示的值是仅供参考的标称值。 1.3 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。 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。 =====意义和用途====== 4.1 本试验方法旨在作为一种快速经验试验，以确定塑料薄膜中的增塑剂或其他可提取成分在浸入家庭常用液体中时的损失。

1.1 This test method for resistance of plastic films to chemicals covers the measurement of the weight loss of film after immersion in chemicals. Note 1: There is no known ISO equivalent to this standard. Note 2: Film is defined as sheeting having nominal thickness not greater than 0.25 mm (0.010 in.), in accordance with Terminology D883 . 1.2 The values stated in SI units are to be regarded as standard. The values stated in other units are nominal values given 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. 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. ====== Significance And Use ====== 4.1 This test method is intended to be a rapid empirical test to determine the loss of the plasticizer or other extractable components from the plastic film when immersed in liquids commonly used in households.
