Over deze norm
1.1 This test method covers a procedure for determining the ability of a coating film and its substrate to resist shattering, cracking, or chipping when the film and substrate are distended beyond their original form by impact.
1.2 This test method does not measure impact resistance but uses rapid impact to improve Test Methods D522, another test method for flexibility. Since the impact of the coating is almost instantaneous, all of the problems associated with time variables in the mandrel tests are eliminated.
1.3 This test method is similar in content but not technically equivalent to Test Method D2794.
1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
