This test method is used for the calibration of a block-on-ring testing machine by measuring the friction and wear properties of a calibration fluid under the prescribed test conditions.

The user of this test method should determine to his or her own satisfaction whether results of this test procedure correlate with field performance or other bench test machines. If the test conditions are changed, wear values can change and relative ratings of fluids can be different.

1.1 This test method covers the calibration and operation of a block-on-ring friction and wear testing machine.

1.2 The values stated in either SI (metric) units or inch-pound units to be regarded separately as standard. Within the text the inch-pound units are shown in brackets. The values stated in each system are not exact equivalents; therefore each system must be used independently of the other. Combining values of the two systems may result in noncomformance with the standard.

1.3 This 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 and health practices and determine the applicability of regulatory limitations prior to use.
