ISO 17872:2007 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 micrometres. 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.
ISO 17872:2007 covers the scribing of metallic panels or test pieces made from
- chemically treated steel,
- aluminium or aluminium alloy, and
- chemically treated aluminium.
It does not cover the scribing of galvanized or electroplated metal or clad aluminium panels.
