26、USSIONThe complete movement for an abrasion cycle isdependent on the action of the abrasion machine and the test methodused. It may consist of one back-and-forth unidirectional movement orone circular movement, or a combination of both. D3885abrasion cycle, nfor the Martindale Abrasion Tester, 16 ru

D4966abrasion cycle, nin abrasion testing, one or more move-ments of the abradant across a material surface, or thematerial surface across the abradant, that permits a return toits starting position.DISCUSSIONThe abrasion cycle is depend
28、ent on the programmedmotions of the abrasion machine and the test standard used. It mayconsist of one back-and-forth unidirectional movement such as for theflexing and abrasion test method; a circular movement such as for therotary platform test method, or a combination of both such as for theinflat
