1.1 本试验方法通过两个不同的程序评估外部绝缘和饰面系统（EIFS）或其单个组件的拉伸粘附性能:程序A，干燥处理和试样测试；和程序B，试样的湿处理和测试。 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- 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====== 5.1 保持EIFS组件之间以及与基板之间的足够拉伸附着力对于系统的长期性能至关重要。 5.2 通过本试验方法获得的拉伸粘附性能并不代表EIFS墙体组件的风荷载或其他结构和水分相关特性。使用本试验方法的拉伸粘附性能被用作评估基材和比较粘合剂的因素之一。

1.1 This test method evaluates the tensile-adhesion performance of an exterior insulation and finish System (EIFS) or its individual components by two different procedures: Procedure A, Dry Conditioning and Testing of Specimens; and Procedure B, Wet Conditioning and Testing of Specimens. 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 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 Maintenance of adequate tensile adhesion of EIFS components to each other, and to the substrate are essential for long term performance of the system. 5.2 The tensile-adhesion properties obtained by this test method are not purported to be representative of wind load or other structural and moisture related properties of the EIFS wall assembly. Tensile-adhesion properties using this test method are used as one of the factors in evaluating substrates and to compare adhesives.
