This Standard sets out methods for the size analysis of higher rank coal (i.e. coal as defined in AS 2096 as having a gross specific energy of 21 MJ/kg or greater on an ash-free, moist basis and a gross specific energy of 27 MJ/kg or greater on a dry, ash-free basis).Very fine coal (less than 45 mm) may be sized using microscopic, sedimentation or surface area measurement methods which are outside the scope of this Standard.
