27、ss a material surface, or the material surfaceacross the abradant, that permits a return to its starting position.DISCUSSIONThe abrasion cycle is dependent on the programmed motions of the abrasion machine and the test standard used. It may consist of oneback-and-forth unidirectional movement such a
28、s for the flexing and abrasion test method; a circular movement such as for the rotary platform testmethod, or a combination of both such as for the inflated diaphragm test method. For the oscillatory cylinder abrasion method, an abrasion cycleconsists of one double-rub. See double-rub. D13.60 D4157
