Status: active
Page Count: 14
ICS Code (Paints and varnishes): 87.040
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,and sea water immersion as used in the test method specified in ISO 15711. 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;

- rusting in accordance with ISO 4628-3;

- cracking in accordance with ISO 4628-4;

- flaking in accordance with ISO 4628-5;

- filiform corrosion in accordance with ISO 4628-10.
