This International Standard provides description of a cone procedure for determining an uncompacted bulk
density of crushed coal less than 37 mm in size, such as is charged into coke ovens. It focuses on the
uncompacted bulk density of coal resulting from flowing the material into a measuring container (box) in the
absence of compacting forces.
This International Standard does not cover procedures for determining a compacted coal bulk density nor to the
testing of fine or powdered coal (for boiler or utility application) nor to the determination of bulk density of coal in
storage piles.
