This part of 2812 specifies spotting methods for determining the resistance of an individual layer or multilayer system of coating materials to the effects of liquids or paste-like products.
These methods enable the testers to determine the effects of the test substance on the coating and, if
necessary, to assess the damage to the substrate.
