This document specifies a field method for the assessment of the surface density of various water-soluble salts on steel surfaces, before and\/or after surface preparation, by conductometric determination. The individual surface densities of the salt composition like chlorides, sulphates, sodium, etc, cannot be determined by this method.<\/p>\n
This method assesses only contaminants that forms an electrolyte (ions) when in contact with water. These represent the greater part of the contaminants.<\/p>\n
