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.
Abstract
Overview
ISO 2812-4:2017 - Paints and varnishes: Determination of resistance to liquids - Part 4: - specifies laboratory procedures to evaluate how individual-layer or multi-layer coating systems resist exposure to liquids and paste‑like substances. The standard defines spotting test procedures that reveal coating damage and, where needed, allow assessment of substrate attack. Typical test substances include fuels, automotive fluids, laboratory chemicals (with CAS numbers listed), and biological deposits (e.g., simulated bird droppings).
