scope:

This International Standard specifies requirements for multilayer materials for the manufacture of thin-walled plain bearings (half bearings, bushes, thrust washers). The multilayer materials consists of a steel backing, the bearing layer (cast, sintered, roll bonded) and, possibly, and overlay. The chemical composition refers to the original unprocessed material and is intended to be measured on representative samples. Testing results on final bearings can be due to the influence of bearing production. Therefore, these results cannot be compared with data given in this International Standard.

NOTE Environmental concerns will, in the future, restrict the use of some materials such as lead.
