ISO 6272-2:2011描述了一种用于评估涂料，清漆或相关产品的干膜在基材下遭受由重量下降引起的变形时从基材开裂或剥离的阻力的方法，在标准条件下下降，作用在一个小面积的球形压头。 注意术语“冲击”和“耐冲击性”用于ISO 6272-2的标题和文本，但使用的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影响。 由于该测试方法的可重复性差，当结果以数值表示时，该方法应限于仅在一个实验室进行测试。当使用排名代替数值时，实验室间协议得到改善

ISO 6272-2:2011 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, dropped under standard conditions, acting on a small-area spherical indenter. NOTE The terms "impact" and "impact resistance" are used in the title and text of ISO 6272-2, but an important characteristic of the apparatus used is that it should produce rapid deformation rather than a true impact. Because of the poor reproducibility of this test method, the method should be restricted to testing in only one laboratory when the results are expressed as numerical values. Interlaboratory agreement is improved when ranking is used in place of numerical values.
