1.1 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 to 10°C after a prescribed preheat and controlled cooling to the final test temperature.

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

1.3 This test method uses the millipascal second (mPaμs) as the unit of viscosity. One millipascal second is equal to one centipoise.

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.
