This part of ISO 4628 specifies a method for assessing delamination and corrosion around a scribe or other artificial defect on a coated panel or other coated test specimen, caused by a corrosive environment. This part of ISO 4628 does not cover evaluation of pitting corrosion or pit depth. NOTE 1 Examples of corrosive environments are artificial atmospheres such as salt spray, as used in the test method specified in ISO 9227,[7] and sea water immersion as used in the test method specified in ISO 15711.[8] Natural environments can also be used. NOTE 2 The extent of other defects can also be determined at the same time as delamination and corrosion. Methods are given as follows: — blistering in accordance with ISO 4628-2;[2] — rusting in accordance with ISO 4628-3;[3] — cracking in accordance with ISO 4628-4;[4] — flaking in accordance with ISO 4628-5;[5] — filiform corrosion in accordance with ISO 4628-10.[6]
