Scope: 1.1 This standard specifies the laboratory measurement method for the apparent viscosity of engine oil. 1.2 This standard is applicable in the range of -5°C to -35°C, the shear stress is about 50 000 Pa to 100 000 Pa, and the shear rate is 10⁵s^-1 to 10 ⁴s^-1, engine oil with a viscosity between 500 mPa·s and 25 000 mPa·s. 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 procedures for determining the apparent viscosity of engine oils using a cold start simulator (CCS). 1.3 Appendix A is a dedicated procedure for the determination of highly viscoelastic samples. 1.4 This standard adopts [SI] International System of Units. 1.5 This standard involves certain hazardous materials, operations and equipment, but does not make recommendations on all safety issues related to this. Therefore, it is necessary for users to establish appropriate safety and protective measures and determine the applicability of relevant regulatory limitations before using this standard.
