This International Standard gives a method of evaluating the condition of decorative and protective metallic andinorganic coated panels or articles which have been exposed to corrosive environments for test or for otherpurposes.It is applicable to test panels or components exposed to natural atmospheres, in mobile or static conditions, orsubjected to accelerated tests.NOTE 1Examples of such tests are given in the Bibliography.This International Standard recognizes that the protection rating can be assessed objectively in accordance withclause 6. However, the assessment of appearance depends on many subjective factors (see 6.2).NOTE 2The edges of test panels or components may be protected, e.g. by tape or wax (paraffin), if this is an agreed part ofthe test and is recorded in the test report. This is essential if the specimens are cut from larger pieces and have exposeduncoated edges.
