1.1 本试验方法涵盖了确定外部绝缘和饰面系统（EIF）、具有水阻隔涂层的EIF和水阻隔涂层本身的冻融效果的程序。 1.2 以国际单位制或英寸-磅单位表示的数值应单独视为标准值。每个系统中规定的值可能不是精确的等效值；因此，每个系统应相互独立使用。将两个系统的值合并可能会导致不符合标准。 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制定适当的安全、健康和环境实践，并在使用前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====== 5.1 在确定EIF的耐久性时，抗冻融性是一个因素，EIF具有阻水屏障涂层，并且本身具有阻水屏障涂层。

1.1 This test method covers procedures for determining the effect of freezing and thawing of exterior insulation and finish systems (EIFS), an EIFS with water-resistive barrier coatings, and water-resistive barrier coatings by itself. 1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the 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 to 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 ====== 5.1 Resistance to freezing and thawing is a factor when determining the durability of EIFS, an EIFS with water-resistive barrier coatings, and water-resistive barrier coatings by itself.
