Viscosity Cup Standard Calibration Oils
In order to check a viscosity cup’s calibration or to certify it for ISO purposes, it is imperative that viscosity cup standard calibration oils are used. Standard oils have a specified drain time, dependent upon the viscosity cup type (Ford, Shell, Zahn, etc) and the orifice size or cup number used.

Standard Calibration Oils
Silicone standard oils are used to check viscosity measurements. The values are given for 6 different temperatures between 20°C and 27°C (68°F and 80°F).
