ISO 6272-1:20 11描述了一种用于评估油漆、清漆或相关产品的干膜在标准条件下使用直径为20mm的球形压头承受由下落重量引起的变形时对从基底上开裂或剥离的抵抗力的方法。 注意ISO 6272-1的标题和正文中使用了术语“冲击”和“抗冲击性”，但是所用设备的一个重要特征是它应该产生快速变形而不是真正的冲击。 可以应用所描述的方法 作为通过/失败测试，该测试从一个跌落高度和指定质量进行，以便测试是否符合特定规范； 或作为分类测试，通过逐渐增加跌落高度和/或质量来确定涂层从其基底破裂或剥离的最小质量和/或跌落高度。

ISO 6272-1:2011 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 to a deformation caused by a falling weight, with a 20-mm-diameter spherical indenter, dropped under standard conditions. NOTE The terms "impact" and "impact resistance" are used in the title and text of ISO 6272-1, but an important characteristic of the apparatus used is that it should produce rapid deformation rather than a true impact. The method described can be applied

• either as a pass/fail test, the test being carried out from one 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.
