1.1 This test method covers laboratory procedures for de-termining the sliding wear of ceramics, metals, and othercandidate wear-resistant materials using a linear, reciprocatingball-on-flat plane geometry. The direction of the relativemotion between sliding surfaces reverses in a periodic fashionsuch that the sliding occurs back and forth and in a straightline. The principal quantities of interest are the wear volumesofthe contacting ball and flat specimen materials; however, thecoefficient of kinetic friction may also be measured using themethod described. This test method encompasses both unlu-bricated and lubricated testing procedures. The scope of thistest method does not include testing in corrosive or chemicallyaggressive environments.
