1.1 本指南涵盖了室内环境中用于单元化、加固和码垛的拉伸膜的选择、规格和使用的推荐指南。这可能包括在仓库、封闭集装箱（如卡车拖车或铁路货车）和相关转运站中的储存或运输，或两者兼有。本指南不涵盖与户外暴露相关的性能问题。 1.1.1 拉伸膜的性能特性可能会受到极端温度的负面影响。 1.2 以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 1.3 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。 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 本指南用于用户选择、规范和应用拉伸膜材料。买方和卖方之间可以使用它来达成采购规范。

1.1 This guide covers recommended guidelines for the selection, specification, and use of stretch films for unitizing, reinforcing, and palletizing for indoor environments. This can include storage or transport, or both, in warehouses, closed containers such as truck trailers or rail boxcars, and associated transfer terminals. This guide does not cover the performance issues associated with outdoor exposure. 1.1.1 Performance characteristics of stretch film may be negatively affected by extreme temperatures. 1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 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 guide is for user selection, specification, and application of stretch film materials. It may be used between the buyer and seller to arrive at purchase specifications.
