1.1This test method covers the measurement of the apparent viscosity of engine oil at low temperatures.
1.2A shear rate of approximately 0.2 s-1 is produced at shear stresses below 100 Pa. Apparent viscosity is measured continuously as the sample is cooled at a rate of 1 °C/h over the range −5 °C to −40 °C, or to the temperature at which the viscosity exceeds 40 000 mPa·s (cP).
1.3The 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.
1.4Applicability to petroleum products other than engine oils has not been determined in preparing this test method.
1.5The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.6This 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.7This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
