Principles of method if other than guideline:

Viscosity is a measure of the resistance of a fluid which is being deformed by either shear stress or tensile stress. The Kinematic viscosity is the dynamic (absolute) viscosity divided by the density. The API gravity is equivalent to the density of the product at a specified temperature, in this case 15 ºC. The test sample DE11657 (10 mL) was loaded into a plastic syringe then 8 mL of sample was flushed through the machine (Anton PAAR Stabinger SVM 3001 Viscometer). The ‘viscosity index’ method was run and an extra 1 mL of sample was flushed through the machine, as instructed, before the measurements began. The viscosity and density of the sample was measured at 40 and 100 ºC, respectively then the API gravity at 15 ºC was automatically calculated.

GLP compliance:

no
