Full Description

1.1This test method covers evaluating the lubricity of diesel fuels using a pump rig test and Stanadyne Model DB4427-4782 pumps.

Note 1:Other pumps may be used if a correlation between pump performance factors and fuel lubricity has been developed.

1.2This test method is applicable to any fuel used in diesel engines, including those which may contain a lubricity enhancing additive.

1.3The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.4This 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.
