This Guide describes a method for the determination of the apparent relative density of bulk samples of coal and a method for coke.
Care should be taken when expressing results using this method as the moisture condition of the sample at the time of analysis may be variable due to preparation and handling conditions and be different to the moisture basis determined for other parameters.
The methods are as follows:
Coal This method is applicable to porous coals and single-lump samples that do not break down in water, and for coals that do not absorb water to a significant extent under the conditions of the test.
Coke The drainage method is used to take into account the difficulties in the determination of the apparent relative density of coke due to water draining out of large pores after immersion in water. This may be overcome by limiting the drainage period to a minimum of 10 s.
