Scope

This standard specifies the test method for determining the dynamic viscosity of lubricants at low shear rates using a Brockfeldt viscometer under appropriate torque conditions. This standard applies to the viscosity range of 500 mPa s~900 000 mPa s, and the temperature range is the allowable temperature range of the Brock Felt viscometer.
