1.1 该试验方法适用于现场和实验室，用于量化制备混凝土表面轮廓的深度。也可用于未经处理的混凝土表面。 1.2 以国际单位制表示的数值应视为标准值。国际单位制后括号中给出的值仅供参考，不被视为标准值。 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====== 4.1 涂层和衬里与混凝土表面的适当结合需要适当清洁，并经常需要对混凝土进行粗糙处理以增加表面积。粗糙度也称为表面轮廓，可通过喷砂清理、酸蚀或各种冲击/翻松电动工具施加到混凝土中。由此产生的表面轮廓深度会影响涂层/衬里的附着力和性能。涂料/衬里制造商或设施所有者，或两者都经常指定在产品安装之前对混凝土表面进行清洁和粗化。本文描述的程序使用户能够直接从多个位置的制备混凝土表面定量确定轮廓。该程序类似于试验方法B中所述的程序 D4417 ，解决了喷砂清理钢表面表面轮廓的测量。

1.1 This test method is suitable for both field and laboratory use to quantify the depth of surface profile of prepared concrete. It may also be used on unprepared concrete surfaces. 1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered 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 ====== 4.1 Proper bonding of coatings and linings to concrete surfaces requires proper cleaning and frequently requires the concrete to be roughened to increase the surface area. The roughness, also known as surface profile, can be imparted into concrete by abrasive blast cleaning, acid etching or various impact/scarifying power tools. The resulting surface profile depth can influence coating/lining adhesion and performance. Coating/lining manufacturers or facility owners, or both, frequently specify cleaning and roughening of the concrete surface prior to product installation. The procedure described herein enables the user to quantitatively determine the profile directly from the prepared concrete surface in multiple locations. The procedure is similar to that described in Method B of Test Methods D4417 , which addresses measurement of surface profile on abrasive blast cleaned steel surfaces.
