\-▐kō-ә-▐fi-shәnt\ n Method for reporting the result of an abrasion test using the falling sand abrasion tester, in which it is assumed that the abrasion resistance is proportional to the film thickness.
where:
W1 = grams of abrasive and holder before tests,
W2 = grams of abrasive and holder after test, and
T = thickness of coating in mils (0.001 in.) (0.025 mm)
