IP 267-1984 (2004) Determination of the viscosity of motor vehicle fluids at low temperatures. The Brockfeldt Viscosity meter is a standard method for determining the viscosity of motor vehicle fluids (e.g. lubricating oils, hydraulic oils, etc.) at low temperatures. The standard specifies the measurement of the apparent viscosity of liquids at low shear rates using the Brockfeldt Viscosity meter in the Temperature range of -40 ° C to + 5 ° C. It is applicable in the viscosity range of 500 mPa · s to 1,000,000 mPa · s. Through this method, the flowability and lubrication performance of motor vehicle liquids in low temperature environments can be evaluated, which provides an important basis for the quality control and formulation optimization of lubricating oils.
