Organization: ASTM
Publication Date: 1 November 1967
Status: inactive
Page Count: 7
ICS Code (Bearings in general): 21.100.01
scope:

This specification covers copper-base sintered metal powder, oil impregnated, bearings of two compositions and three types depending on density.

NOTE 1-The two compositions are intended to be equivalent so far as application is concerned, the different compositions representing the products supplied by different manufacturers for the same service.

NOTE 2-The values stated in U. S. customary units are to be regarded as the standard. The metric equivalents of U.S. customary units given in the body of the standard and in the appendix may be approximate.
