1.1 本试验方法涵盖了一个测量喷涂耐火材料对钢材腐蚀的程序。 1.2 这些SFRM包括与结构构件直接接触的喷涂纤维材料和胶结材料。 1.3 此测试方法仅适用于实验室程序。 1.4 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。 1.5 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。 1.6 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====== 5.1 本试验方法旨在确定直接应用的SFRM的相对腐蚀性能，以提供可用性指示。 应用于结构构件和组件的SFRM的满意性能取决于其承受结构使用寿命期间发生的各种影响的能力，以及其在火灾条件下的满意性能。 5.2 该试验方法评估了SFRM引起的钢的相对腐蚀，并确定SFRM的存在是否会增加、减少或对钢的腐蚀特性没有影响。

1.1 This test method covers a procedure for measuring the corrosion to steel induced by sprayed fire-resistive material. 1.2 These SFRMs include sprayed fibrous and cementitious materials applied directly in contact with the structural members. 1.3 This test method is applicable only to laboratory procedures. 1.4 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. 1.5 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. 1.6 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 It is the intent of this test method to determine relative corrosive properties of direct applied SFRM that provides an indication of serviceability. Satisfactory performance of SFRM applied to structural members and assemblies depends upon its ability to withstand the various influences that occur during the life of the structure, as well as upon its satisfactory performance under fire conditions. 5.2 This test method evaluates the relative corrosion of steel induced by SFRM and determines whether the presence of SFRM increases, decreases, or has no effect on the corrosion characteristics of steel.
