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.
This method assesses only contaminants that forms an electrolyte
(ions) when in contact with water. These represent the greater part
of the contaminants.
