Beschichtungsstoffe - Prüfung der Widerstandsfähigkeit bei schlagartiger Verformung (Schlagprüfung) - Teil 1: Prüfung durch fallendes Gewichtsstück, große Prüffläche (ISO 6272-1:2011); Deutsche Fassung EN ISO 6272-1:2011
Overview
This part of ISO 6272 describes a method for evaluating the resistance of a dry film of paint, varnish or related product to cracking or peeling from a substrate when it is subjected, under standard conditions, to a deformation caused by a falling weight, with a 20-mm-diameter spherical indenter. The method described can be applied - either as a pass/fail test, the test being carried out from a specified drop height and with a specified mass, so as to test compliance with a particular specification; - or as a classification test, to determine, by gradually increasing the drop height and/or the mass, the minimum mass and/or drop height for which the coating cracks or peels from its substrate. The Committee responsible for this standard is NA 002-00-07 AA "Allgemeine Prüfverfahren für Beschichtungsstoffe und Beschichtungen" ("General test methods for coating materials and coatings") at DIN.
