Historical Standard: ASTM D5293-99ae1 Standard Test Method for Apparent Viscosity of Engine Oils Between -5 and -35 o C Using the Cold-Cranking Simulator
SUPERSEDED (see Active link, below)
ASTM D5293
1. Scope
1.1 This test method covers the laboratory determination of apparent viscosity of engine oils by cold cranking simulator (CCS) at temperatures between -5 and -35 o C at shear stresses of approximately 50 000 to 100 000 Pa and shear rates of approximately 10 5 to 10 4 s -1 and viscosities of approximately 500 to 25 000 mPas. The range of an instrument is dependent on the instrument model and software version installed. These results are related to engine-cranking characteristics of engine oils.
1.2 A special procedure is provided in Annex A1 for highly viscoelastic oils.
1.3 Procedures are provided for both manual and automated determination of the apparent viscosity of engine oils using the cold-cranking simulator.
1.4 A special manual procedure is provided in Annex A1 for highly viscoelastic oils.
1.5 The values stated in SI units are to be regarded as the 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. Specific warning statements are given in 7.1, 7.2, 7.3, and 7.5 and Section 8.
