ISO 8503-2:2012描述了一种评估轮廓等级的视觉和触觉方法，该轮廓由ISO 8504-2中描述的一种喷砂清理程序产生。 该方法使用ISO表面轮廓比较器在现场评估涂漆或其他保护处理前的表面粗糙度。 该方法适用于使用抛丸磨料或粗砂磨料进行喷砂清理的钢表面，但仅适用于ISO 8501？1的Sa 2？和Sa 3级，其中整个受试表面显示整体喷砂清理外观。 适用于用金属或非金属材料清洁过的表面- 金属磨料。

ISO 8503-2:2012 describes a visual and tactile method for assessing the grade of the profile which is produced by one of the abrasive blast-cleaning procedures described in ISO 8504？2. The method uses ISO surface profile comparators for assessing, on site, the roughness of surfaces before the application of paint or other protective treatments. The method is applicable to steel surfaces which have been blast-cleaned by use of either shot abrasives or grit abrasives, but is only applicable to grades Sa 2？ and Sa 3 of ISO 8501？1 where the entire surface under test shows an overall blast-cleaned appearance. lt is applicable to surfaces which have been cleaned with either metallic or non-metallic abrasives.
