ASTM E238 Standard Method for Pin Type Bearing Testing of Metallic Materials

EUROLAB laboratory provides testing and compliance services within the scope of ASTM E238 standard. The ASTM E238 standard covers pin type bearing testing of metallic materials to determine bearing yield strength and bearing strength. The presence of residual oils on the bearing surfaces can significantly reduce the bearing yield strength value obtained by this method.

ASTM E238 Standard Method for Pin Type Bearing Testing of Metallic Materials

ASTM E238 describes the determination of bearing strength and bearing yield strength of metallic materials by a pin-type bearing test. The bearing load is usually applied to the specimen via a tight-fitting cylindrical pin, which is harder and stronger than the test specimen.

Bearing strength is defined as the maximum bearing stress a material can withstand. Bearing yield strength is the bearing stress at which a material exhibits a certain limiting deviation from the proportionality of bearing stress to bearing strain. Bearing properties are useful in comparing the design of materials and structures under pin unrestricted conditions.

The data provide a measure of the load-bearing capacity of an edge of material loaded with a tight-fitting cylindrical pin through a hole located some distance from the specimen edge. EUROLAB is equipped to perform variations of this test at temperatures up to 2500 °F.

Bearing properties are useful in comparing the design of materials and structures under pin unrestricted conditions. Before performing ASTM E238, it is important to read the entire specification in the relevant ASTM publication.

Values ​​stated in inch-pound units should be considered standard. Values ​​in parentheses are mathematical conversions to non-standard SI units, provided for informational purposes only.

This standard does not purport to address all, if any, safety concerns associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory restrictions prior to use.
