Abstract
1 Scope 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](/search?q=ISO%C2%A09227), [7] and sea water immersion as used in the test method specified in [ISO 15711](/search?q=ISO%C2%A015711). [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](/search?q=ISO%C2%A04628-2); [2]
— rusting in accordance with [ISO 4628-3](/search?q=ISO%C2%A04628-3); [3]
— cracking in accordance with [ISO 4628-4](/search?q=ISO%C2%A04628-4); [4]
— flaking in accordance with [ISO 4628-5](/search?q=ISO%C2%A04628-5); [5]
— filiform corrosion in accordance with [ISO 4628-10](/search?q=ISO%C2%A04628-10).<s...
