ASTM E238-84(2002) (R1984)

1.1 This test method covers a pin-type bearing test of metallic materials to determine bearing yield strength and bearing strength.

Note—The presence of incidental lubricants on the bearing surfaces may significantly lower the value of bearing yield strength obtained by this method.

1.2 The values stated in inch-pound units are to be regarded as the standard.

1.3 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

The data obtained from the bearing test are the bearing ultimate and yield strength. The data provide a measure of the load-carrying capacity of a material edge loaded with a close-fitting cylindrical pin through a hole located a specific distance from the specimen edge.

Bearing properties are useful in the comparison of materials and design of structures under conditions where the pin is not restricted.
