Organization: ASTM
Publication Date: 1 July 2014
Status: inactive
Page Count: 7
ICS Code (Lubricants, industrial oils and related products): 75.100
scope:

This test method covers the measurement of the viscosity of drive line lubricants (gear oils, automatic transmission fluids, and so forth) with a constant shear stress viscometer at temperatures from -40 °C to 10 °C after a prescribed preheat and controlled cooling to the final test temperature. The precision is stated for test temperatures from -40 °C to -26 °C. 

The applicability of this particular test method to petroleum products other than drive line lubricants has not been determined. 

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

This standard uses the SI based unit of milliPascal second (mPa·s) for viscosity which is equivalent to centiPoise (cP). 

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.
