GB/T 18856.4-2008
Test methods for coal water mixture - Part 4: Determination of apparent viscosity

GB/T 18856.4-2008 specifies the method for determining the apparent viscosity of coal water mixture, primarily using a rotational viscometer. This method measures at a specific shear rate and is used to evaluate the fluidity and pumpability of the coal water mixture, which is a key quality indicator for its use as a fuel.
