<p>This Technical Report provides information on the effect of water-soluble chloride and sulfate contamination levels</p>
<p>on steel surfaces, before the application of paint or related products to surfaces prepared in accordance with</p>
<p>standard mechanical or blast-cleaning surface preparation methods.</p>
<p>NOTE The tolerance for water-soluble salt contamination may be different for different paint types.</p>
<p>This information may be used when evaluating the adequacy of surface preparation prior to painting.</p>
<p>This document is concerned only with measured levels of salt contamination based upon either laboratory or field</p>
<p>testing. The levels of soluble chloride and sulfate discussed in this document are to be compared using soluble</p>
<p>surface densities of the species as determined after extraction in accordance with ISO 8502-6 (the Bresle method),</p>
<p>or other methods giving equivalent results. Total soluble-salt contamination may be determined by conductometric</p>
<p>testing, but such testing will not determine the nature and concentration of the specific salts present, e.g. whether</p>
<p>chloride or sulfate is present, or its concentration.</p>
<p>This document does not define specific levels of cleanliness or methods of salt removal.</p>
