Document: ISO 8502-9:1998
This part of ISO 8502-9: 1998 describes a field method for assessing the total surface density of various water-soluble salts (mainly chlorides and sulphates) on steel surfaces before and / or after surface preparation.
Individual surface densities of chlorides, sulfates, etc. cannot be determined by this method. With this method, only the presence of ionic contaminants is assessed. They represent most of the pollution.
