Scope and field of application
This part of IS0 8503 describes a visual and tactile method for assessing the grade of the profile that has been produced by one of the abrasive blast-cleaning procedures described in IS0 8504-2.
The method uses IS0 surface profile comparators for assessing, on site, the roughness of surfaces before the application of paint or other protective treatments.
NOTE - Where appropriate, IS0 surface profile comparators may be used for assessing the roughness profile of other abrasive blast-cleaned substrates and, in addition, their use is not restricted solely to surfaces that are to be painted.
The method is applicable to steel surfaces that have been blast-cleaned by use of either shot abrasives or grit abrasives but is only applicable for grades Sa 2 l/z and Sa 3 of IS0 8501-I when the entire surface under test shows an overall blastcleaned appearance.
It is applicable to surfaces that have been cleaned with either metallic or non-metallic abrasives.
