ISO 6272-2:2011描述了一种评估油漆、清漆或相关产品的干膜在标准条件下下落，作用于小面积球形压头，使其受到下落重量引起的变形时，从基材上开裂或剥落的阻力的方法。 注:ISO 6272-2的标题和文本中使用了术语“冲击”和“抗冲击性”，但所用仪器的一个重要特征是，它应产生快速变形，而不是真正的冲击。 由于该试验方法的再现性较差，当结果以数值表示时，该方法应仅限于在一个实验室进行试验。当使用排名代替数值时，实验室间的一致性得到改善。

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.
