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, 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 this part of ISO 6272, but animportant 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 asto test compliance with a particular specification;- or as a classification test, to determine, by gradually increasing the drop height and/or the mass, theminimum mass and/or drop height for which the coating cracks or peels from its substrate.
