3.1 coke bulk density
ρ 1
mass of a portion of a sample of coke divided by the volume of the container, which is filled by that portion under specified conditions
4 Principle
A weighed container of known volume is filled with coke and the increase in mass is determined.
5 Apparatus
5.1 Container, such as a wagon or skip, capable of holding at least 3 metric tonnes of the coke.
5.2 Machine, machine, capable of weighing the container and its contents to an accuracy of 0,2 %.
6 Procedure
Weigh the empty container (5.1) on the weighing machine (5.2). Measure the internal dimensions of the container to the nearest 1 cm and calculate its capacity. If the container is already fully charged, it should be weighed with the coke first, then be weighed empty and also be measured. With the container on a level surface, carefully charge the coke into it until pieces of coke project above the top of the container across the whole surface. Slide a straightedge across the top of the container and remove any pieces of coke, which obstruct its passage. Weigh the charged container.
