Beschichtungsstoffe - Prüfung der Steinschlagfestigkeit von Beschichtungen - Teil 2: Einzelschlagprüfung mit geführtem Schlagkörper (ISO 20567-2:2017); Deutsche Fassung EN ISO 20567-2:2017
Overview
In the automobile industry, multi-layer paint coatings are applied to car bodies for protection. Grit, road-metal 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. ISO 20567-1 describes multi-impact testing, while this document and ISO 20567-3 describe single-impact tests. This document specifies a method to evaluate the resistance of automobile finishes and other coatings to the impact of a wedge-shaped body which is projected onto the surface under test to simulate the impact of stones. This responsible German standardization committee is Working Group NA 002-00-07-09 AK "Automobilbeschichtungen" ("Automotive coatings") at DIN Standards Committee Coatings and Coating Materials (NAB).
