1.1 这些测试方法包括在现场、车间和实验室测量喷砂清理表面轮廓的技术描述。这些试验方法未涵盖适用于实验室使用的其他技术。 1.2 方法B也适用于测量使用电动工具产生的轮廓。 注1: 本标准中的方法B程序适用于平面。根据曲面的半径，结果可能具有更大的可变性，值和平均值较低。 1.3 SSPC标准SSPC-PA 17为确定是否符合表面轮廓要求提供了额外指南。 1.4 以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。 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。 1.6 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====== 5.1 表面轮廓高度已被证明是钢上各种涂层性能的一个因素。因此，应在涂覆涂层之前测量表面轮廓，以确保制备的表面符合保护涂层制造商或涂层作业规范规定的轮廓要求。 注2: 峰值计数/峰值密度已被证明是应用于钢的各种涂层性能的一个因素。根据罗珀、韦弗和布兰登的研究 6. ，峰值计数的增加可以提高某些涂层与制备钢的附着力，并在涂层在使用中受损时提供更大的抗腐蚀咬边能力。 注3: 光学显微镜方法作为表面轮廓测量方法a和B的参考方法。轮廓深度指定基于平均最大轮廓的概念( h 最大值）；该值通过平均给定数量（通常为20）的标准测量显微镜视野中的最高峰到最低谷测量值来确定。之所以这样做，是因为有证据表明，任何一个小区域的涂层性能主要受该区域最高表面特征的影响，而不是受平均粗糙度的影响。 7.

1.1 These test methods cover the description of techniques for measuring the profile of abrasive blast cleaned surfaces in the field, shop, and laboratory. There are other techniques suitable for laboratory use not covered by these test methods. 1.2 Method B may also be appropriate to the measurement of profile produced by using power tools. Note 1: The Method B procedure in this standard was developed for use on flat surfaces. Depending on the radius of the surface, the results could have greater variability with lower values and averages. 1.3 SSPC standard SSPC-PA 17 provides additional guidance for determining conformance with surface profile requirements. 1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 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 The height of surface profile has been shown to be a factor in the performance of various coatings applied to steel. For this reason, surface profile should be measured prior to coating application to ensure conformance of a prepared surface to profile requirements specified by the manufacturer of a protective coating or the coating job specification. Note 2: The peak count/peak density has been shown to be a factor in the performance of various coatings applied to steel. According to research performed by Roper, Weaver and Brandon 6 , an increase in peak count can improve the adhesion of some coatings to the prepared steel, as well as provide greater resistance to corrosion undercutting once the coating becomes damaged in service. Note 3: Optical microscope methods serve as a referee method for surface profile measurement methods A and B. Profile depth designations are based on the concept of mean maximum profile ( h max); this value is determined by averaging a given number (usually 20) of the highest peak to lowest valley measurements made in the field of view of a standard measuring microscope. This is done because of evidence that coating performance in any one small area is primarily influenced by the highest surface features in that area and not by the average roughness. 7
