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.
