标准摘要
[中文适用范围]： ISO 8503 的这一部分描述了一种视觉和触觉方法，用于评估由 ISO 8504-2 中描述的喷砂清理程序之一产生的型材的等级。 该方法使用 ISO 表面轮廓比较器在涂漆或其他保护处理之前现场评估表面的粗糙度。 注：在适当的情况下，ISO 表面轮廓比较器可用于评估其他喷砂清理基材的粗糙度轮廓，此外，它们的使用不仅限于要涂漆的表面。 该方法适用于使用喷丸磨料或砂粒磨料喷砂清理的钢表面，但仅适用于 ISO 8501-1 的 Sa 2½ 和 Sa 3 级，其中整个测试表面显示出整体喷砂-清洁的外观。 它适用于已用金属或非金属磨料清洁过的表面。 [外文原描述]： 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 2½ 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.
