This document specifies a cone procedure for determining an uncompacted bulk density of crushed coal up to −45 mm nominal top size, as it is handled in industrial practices. 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. The determination of the bulk density of coal charged into coke ovens is a typical example.
This document also provides a method for determining the bulk density of dry powdered coal at −63 micrometres for boiler or utility application. It does not cover the determination of bulk density of coal in storage piles.
BSI recommends this version of standard for organisations operating in or with the UK. The ISO edition is available here if required.
