Overview

This part of DIN EN ISO 8503 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. Where appropriate, surface profile comparators can also be used for assessing the roughness profile of other abrasive blast-cleaned substrates. In addition, their use is not restricted solely to surfaces that are to be painted. The method is applicable to steel surfaces which have been blast-cleaned by use of either shot abrasives or grit abrasives. It is only applicable to grades Sa 2 1/2 and Sa 3 of ISO 8501-1 where the entire surface under test shows an overall blast-cleaned appearance. The method is applicable to surfaces which have been cleaned with either metallic or non-metallic abrasives. The underlying International Standard has been prepared by Technical Committee ISO/TC 35 "Paints and varnishes", in collaboration with Technical Committee CEN/TC 139 "Paints and varnishes", the secretariat of which is held by DIN (Germany). The committee responsible for this standard is NA 002-00-10-04 UA "Oberflächenvorbereitung und -prüfung" ("Surface preparation and testing") at DIN.
