ISO 2812-1:2017规定了确定涂层材料的单层或多层系统对液体（非水或糊状产品）影响的阻力的一般方法（包括在文本）。 这些方法使测试人员能够确定测试液体对涂层的影响，并在必要时评估对基材的损伤。

ISO 2812-1:2017 specifies general methods for determining the resistance of an individual-layer or multi-layer system of coating materials to the effects of liquids, other than water, or paste-like products (included implicitly in test liquids mentioned in the text). These methods enable the testers to determine the effects of the test liquid on the coating and, if necessary, to assess the damage to the substrate.
