1.1 This test method covers how to measure the apparent viscosity of used and soot-containing engine oils at low temperatures. 1.2 A shear rate of approximately 0.2 s-1 is produced at shear stresses below 200 Pa. Apparent viscosity is measured continuously as the sample is cooled at a rate of 3C per hour over the range of 5 to 40C. 1.3 The measurements resulting from this test method are viscosity, the maximum rate of viscosity increase (Gelation Index) and the temperature at which the Gelation Index occurs. 1.4 Applicability to petroleum products other than engine oils has not been determined in preparing this test method. 1.5 The values stated in SI units are to be regarded as standard. 1.6 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. |
