5.1 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. |

| 1. Scope | ||||||
|
1.1 This test method covers measurement, in poises, of the apparent viscosity of lubricating greases in the temperature range from −54 to 38°C (−65 to 100°F). Measurements are limited to the range from 25 to 100 000 P at 0.1 s−1 and 1 to 100 P at 15 000 s−1. 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 1.3 WARNING—Mercury has been designated by
many regulatory agencies as a hazardous material that can cause
central nervous system, kidney and liver damage. Mercury, or its
vapor, may be hazardous to health and corrosive to materials.
Caution should be taken when handling mercury and mercury
containing products. See the applicable product Material Safety
Data Sheet (MSDS) for details and EPA’s
website—http://www.epa.gov/mercury/faq.htm—for additional
information. Users should be aware that selling mercury and/or
mercury containing products into your state or country may be
prohibited by law.
1.3.1 In addition, temperature measuring devices such as liquid-in-glass thermometers, thermocouples, thermistors, or platinum resistance thermometers that provide equivalent or better accuracy and precision, that cover the temperature range for ASTM thermometer 49C, may be used. 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. |
