Provides three methods for the determination of the bulk density of crushed higher rank coal and coke.

This Standard sets out the following three methods for the determination of the bulk density of crushed higher rank coal and coke: (a) Uncompacted box method, for coal less than 45 mm nominal top size (see Note to Clause 4.2.3(a)).(b) Measuring cylinder method, for coal typically less than 63 mm as used in pulverized fuel fired boilers and cement kilns.(c) Uncompacted box method for coke.
