Hard coal - Determination of Hardgrove grindability index

ISO 5074:2015 specifies the method for determining the grindability index of hard coal using the Hardgrove machine. It also specifies the procedure for calibrating the test machine and for preparing the standard reference coal samples. NOTE In this International Standard, the term "hard coal" is used as an indication of maturity or rank in the coalification sequence and is not related to the physical properties of the coal.
