Organization: ASTM International
Publication Date: 1 November 2005
Status: inactive
Page Count: 8
significance And Use:

Apparent viscosity versus shear rate information can be useful in predicting pressure drops in grease distribution systems under steady-state flow conditions at constant temperature.

scope:

1.1 This test method covers measurement, in poises, of the apparent viscosity of lubricating greases in the temperature range from 54 to 38C (65 to 100F). Measurements are limited to the range from 25 to 100 000 P at 0.1 s1 and 1 to 100 P at 15 000 s1.

Note 1

At very low temperatures the shear rate range may be reduced because of the great force required to force grease through the smaller capillaries. Precision has not been established below 10 s1.

1.2 This standard uses inch-pound units as well as SI (acceptable metric) units. The values stated first are to be regarded as standard. The values given in parentheses are for information only. The capillary dimensions in SI units in and are 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.
