1.1 本试验方法涵盖了垂直于喷涂在刚性背衬上的耐火材料（SFRM）表面的内聚力/粘附力或粘结强度（拉伸）的测量程序。这些耐火材料包括喷射纤维材料和胶结材料。试验方法适用于第节所述的实验室和现场程序 7. . 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。每个系统中规定的值不一定是精确的等效值；因此，为了确保符合标准，每个系统应独立使用，并且两个系统的值不应合并。 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》中确立的国际公认的标准化原则制定的。 ====意义和用途====== 4.1 该测试方法的目的是确定SFRM的特性，该特性可用于提供其原位可用性的指示。应用于结构构件和组件的SFRM的满意性能取决于其承受施工期间和结构使用寿命期间可能发生的各种影响的能力，以及其在火灾条件下的满意性能。 4.2 关于已安装的含石棉喷涂耐火材料的内聚力/粘附力测试，请参考实践 第1494页 .

1.1 This test method covers a procedure for measuring the cohesion/adhesion or bond strength (tensile) perpendicular to the surface of sprayed fire-resistive material (SFRM) applied to rigid backing. These fire-resistive materials include sprayed fibrous and cementitious materials. The test method is applicable to both laboratory and field procedures as indicated in Section 7 . 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 are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. 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 The intent of this test method is to determine a property of SFRM that may be used to provide an indication of its in-place serviceability. Satisfactory performance of SFRM applied to structural members and assemblies depends upon its ability to withstand the various influences that may occur during construction and during the life of the structure, as well as upon its satisfactory performance under fire conditions. 4.2 For cohesion/adhesion testing of installed asbestos-containing sprayed fire-resistive materials, refer to Practice E1494 .
