Preparation of steel substrates before application of paints and related products - Tests for the assessment of surface cleanliness - Part 2: Laboratory determination of chloride on cleaned surfaces
This part of ISO 8502 describes a method for assessment of chloride-containing salts that are readily soluble in water and are present on a steel surface. The method is also applicable to previously coated surfaces. It is normally to be used in a laboratory using washings sampled from surfaces on site. The method is applicable to the assessment of salts that have been introduced by the cleaning procedure, orthat have deposited on the surface before or after the cleaning.
