Scope

This standard specifies methods for assessing the corrosion state of test panels or test pieces covered with decorative and protective metallic and inorganic coatings after exposure tests in corrosive environments or exposure for other purposes. The method specified in this standard is applicable to test panels or specimens exposed under dynamic or static conditions in the natural atmosphere, and also applicable to test panels or specimens subjected to accelerated tests. This standard recognizes that protection ratings can be made objectively as specified in Clause 6, whereas appearance ratings depend on a number of subjective factors (see 6.2).
