本国际标准规定了两种加速腐蚀试验程序，即方法A和B，用于评估表面处理金属及其合金在大气环境中的腐蚀行为，无论是否涂有油漆。它还规定了使用的仪器。这两项测试涉及盐沉积和恒定绝对湿度下的干/湿条件。 方法A适用于: 金属及其合金（包括耐腐蚀合金） 方法B适用于: 金属及其合金 有涂层的金属及其合金[包括金属涂层（阳极或阴极），有机 涂料和转化涂料]

This International Standard specifies two accelerated corrosion test procedures, Methods A and B, for the evaluation of corrosion behaviour of surface-treated metals and their alloys with and without paint on them in atmospheric environments. It also specifies the apparatus used. The two tests involve salt deposition and dry/wet conditions at a constant absolute humidity. Method A applies to: metals and their alloys (including corrosion-resistance alloys) Method B applies to: metals and their alloys metals and their alloys with coatings [including metallic coatings (anodic or cathodic), organic coatings, and conversion coatings]
