1.1 这些试验方法包括确定结构组件中使用的喷涂耐火材料（SFRM）的厚度和密度的程序。其中包括喷射纤维和水泥类型。试验方法适用于实验室和现场程序，如第节所示 7. . 1.2 这些测试方法要求按照制造商发布的说明应用SFRM。用于将SFRM应用于实验室测试的仪器、材料和程序应与测试方法中所述的任何测试组件的构造所用的相同 第119页 和 电子84 . 1.3 这些测试方法无意建立性能水平。 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 SFRM的某些特性，即厚度和密度是基本的。这些测试方法旨在提供确定这些特性的程序。

1.1 These test methods cover procedures for determining thickness and density of sprayed fire-resistive material (SFRM) used in structural assemblies. These include sprayed fiber and cementitious types. The test methods are applicable to both laboratory and field procedures, as indicated in Section 7 . 1.2 These test methods require the application of SFRM in accordance with the manufacturers’ published instructions. The apparatus, materials, and procedure used to apply the SFRM for laboratory tests shall be the same as is used for the construction of either of the test assemblies described in Test Methods E119 and E84 . 1.3 There is no intent in these test methods to establish levels of performance. 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 Certain properties, namely thickness and density, of SFRM are basic. It is the intent of these test methods to provide procedures to determine these properties.
