1 Scope This Part of GB/T 20624 describes a method for rapidly deforming, by impact with a spherical indenter of diameter 12.7 mm or 15.9 mm, a coating film and its substrate and evaluating the effect of such deformation. Note: The term “impact resistance” is included in the title and text of this Part, but one important characteristic of the apparatus used is that it should produce rapid deformation rather than a true impact. This test method should be restricted to testing in only one laboratory when numerical values are used because of the poor reproducibility of the method. Interlaboratory agreement is improved when ranking is used in place of numerical values. 2 Normative References The following normative documents contain provisions which, through reference in this text, constitute provisions of this Part of GB/T 20624.
