Sets out a laboratory procedure to evaluate the dust/moisture relationship characteristic of a coal and a dust extinction moisture (DEM).

This Standard sets out a laboratory procedure for the dust testing of higher rank coals. The procedure defines a means of evaluating the dust/moisture relationship characteristic of a coal and a dust extinction moisture (DEM).NOTE: In this Standard an experimental dust number of 10 has been used in the example given in Appendix A.
