Test Guidance
The viscosity of the test substance was determined according to ASTM D445-97 Standard Test Method for Kinematic Viscosity of Transparent and Opaque liquids (the Calculation of Dynamic Viscosity).
Method and materials
Viscosities were measured on 235 different QC batches at two temperatures,

The mean values obtained were:
Viscosity at 100°C is 7.16 cSt
Viscosity at 40°C is 52.2 cSt
