Scope

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.
