Scope

1.1 This standard specifies the laboratory measurement method for the apparent viscosity of engine oil.
1.2 This standard is applicable to engine oil with a shear stress of approximately 50,000 Pa to 100,000 Pa, a shear rate of 105 s-1 to 104 s-1, and a viscosity of 500 mPa·s to 25,000 mPa·s within the temperature range of -5 ℃ to -35 ℃. The measurement range of the instrument depends on the model of the instrument and the installed software version. This standard provides both manual and automatic steps for measuring the apparent viscosity of engine oil using a cold start simulator (CCS).
1.3 Appendix A is a dedicated step for measuring high viscoelastic samples.
1.4 This standard uses units of the International System of Units (SI).
1.5 This standard involves certain hazardous materials, operations, and equipment, but does not provide recommendations for all safety issues related to them. Therefore, it is necessary for users to establish appropriate safety and protective measures and determine the applicability of relevant regulatory restrictions before using this standard.
