1.1 本规程涵盖了要求耐化学性的区域内广播或泥浆广播整体地板表面的试样制备方法和测试程序。 1.2 这些地板表面通过各种应用方法进行应用，包括刮板、滚筒、镘刀、缺口镘刀和计量耙，将其应用于适当制备的混凝土基底上。表面在固化时结合到基底上，以提供60密耳（1.5mm）或更大的标称厚度。 1.3 以英寸磅为单位的数值应视为标准。括号中给出的值是国际单位制的数学转换，仅供参考，不被视为标准。 1.4 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。 1.5 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 由于样品的制备方式与现场应用的方式相同，因此试样可被视为特定表面应用的代表。这种方法包括使用刮板、滚筒、镘刀、缺口镘刀和量规耙。 4.2 这些系统以多种方式变化，包括层数或应用步骤、表面光洁度和成分变化。 4.3 在实施该实践过程中获得的结果应作为比较类似应用表面的指南。 尚未尝试将在实际服务时可能影响此类应用程序性能的所有各种因素纳入该实践。

1.1 This practice covers methods for preparing test specimens and testing procedures for broadcast or slurry-broadcast monolithic floor surfacings in areas where chemical resistance is required. 1.2 These floor surfacings are applied by various application methods including squeegees, rollers, trowels, notched trowels, and gage rakes onto suitably prepared concrete substrates. The surfacings bond to the substrate upon curing to provide a nominal thickness of 60 mils (1.5 mm) or greater. 1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.4 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. 1.5 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 Because the sample is prepared in a manner as it would be applied in the field, the test specimens may be considered representative of the application of a specified surfacing. Such methods include application by squeegees, rollers, trowels, notched trowels, and gage rakes. 4.2 These systems vary in several ways, including the number of layers or application steps, the surface finish, and variation in composition. 4.3 The results obtained in carrying out this practice should serve as a guide in comparing similarly applied surfacings. No attempt has been made to incorporate into this practice all of the various factors that may affect the performance of such applications when subjected to actual service.
