ISO 8502-9:1998
Preparation of steel substrates before application of paints and related products - Tests for the assessment of surface cleanliness - Part 9: Field method for the conductometric determination of water-soluble salts
This part of ISO 8502 describes a field method for the assessment of the total surface density of various water-soluble salts (mostly chlorides and sulfates) on steel surfaces before and/or after surface preparation.
The individual surface densities of chlorides, sulfates, etc., cannot be determined by this method.
This method assesses ionic contaminants only. These represent the greater part of the contamination.
