本标准规定了在腐蚀环境中进行过暴露试验或经其他目的的暴露后，装饰性和保护性金属和无机覆盖层所覆盖的试板或试件腐蚀状态的评定方法。本标准规定的方法适用于在自然大气中动态或静态条件下暴露的试板或试件，也适用于经加速试验的试板或试件。

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).
