GB/T 26930.11-2014 "Carbonaceous materials used in the production of primary aluminium—Coal tar pitch—Part 11: Determination of dynamic viscosity" specifies the method for determining the dynamic viscosity of coal tar pitch used in the production of primary aluminium using a rotational viscometer. This method is applicable to liquid pitch within a specified temperature range. By measuring the torque required for the rotor to rotate at a defined shear rate, the dynamic viscosity of the coal tar pitch is calculated.
