Overview
In the automotive industry, multi-layer paint coatings are applied to car bodies for protection. Grit, roadmetal and other materials can damage these coatings in such a way that individual layers come off or the whole coating delaminates from the substrate. Stone chipping can be simulated by means of single- and/or multi-impact tests. This standard specifies a method for the evaluation of the resistance of automobile finishes and other coatings to the impact of a single, free-flying body projected onto the surface under test to simulate the impact of stones. The committee responsible for this standard is NA 002-00-07-09 AK "Automobilbeschichtungen" ("Automotive coatings") at DIN.
Please get in touch with the relevant contact person at DIN if you have problems understanding the content of the standard or need advice on how to apply it.
