Full Description

1.1This test method covers the determination of wear rate and coefficient of friction for self-lubricated materials in rubbing contact by a testing machine2 that utilizes a thrust washer specimen configuration.

Note 1:This machine may also be used to measure coefficient of friction.

1.2The values in SI units are to be regarded as the standard. In cases where materials, products, or equipment are available only in inch-pound units, SI values in parentheses are for information only.

1.3This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.4This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
