ASTM D1404-99

1.1 This test method describes a procedure for the detection and estimation of deleterious particles in lubricating grease.

1.2 This test method is applicable to all lubricating greases. It can also be used to test other semi-solid or viscous materials. Grease fillers, such as graphite and molybdenum disulfide, can be tested for abrasive contaminants by first mixing them into petrolatum or grease known to be free of deleterious particles.

1.3 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system shall be used independently of the other. Combining values from the two systems could result in nonconformance with the standard.

1.4 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.
