<p>This document describes methods of scribing coated steel or test-pieces for corrosion tests, where the coating system is applied at dry film thicknesses of less than 500 μm. It is intended as a guideline only, being based on the results of a collaborative trial with no subsequent corrosion testing having been carried out to determine the suitability of the introduced scribe marks for such tests.</p>
<p>This document covers the scribing of metallic panels or test pieces (chemically treated or not) made from:</p>
<p>— steel;</p>
<p>— galvanized steel;</p>
<p>— aluminium alloys;</p>
<p>— magnesium alloys.</p>
<p>It does not cover the scribing of electroplated metal or clad aluminium panels.</p>
