scope:

This International Standard specifies requirements formultilayer materials for the manufacture of thin-walled plainbearings (half bearings, bushes, thrust washers). The multilayermaterial consists of a steel backing, the bearing layer (cast,sintered, roll bonded) and, possibly, an overlay. The chemicalcomposition refers to the original unprocessed material and isintended to be measured on representative samples. Testing resultson final bearings can be due to the influence of bearingproduction. Therefore, these results cannot be compared with datagiven in this International Standard. NOTE Environmental concernswill, in the future, restrict the use of some materials such aslead.
