Paints and varnishes - Determination of resistance to liquids - Part 4: Spotting methods
ISO 2812-4:2017 specifies spotting methods for determining the resistance of an individual-layer or multi-layer 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.
