適用范圍：This part of ISO 6272 describes a method for evaluating the resistance of a dry film of paint, varnish or relatedproduct to cracking or peeling from a substrate when it is subjected to a deformation caused by a fallingweight, 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 this part of ISO 6272, but animportant 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 onelaboratory when the results are expressed as numerical values. Interlaboratory agreement is improved whenranking is used in place of numerical values.
