ActiveDetermination of apparent relative density of coal
煤的视相对密度测定方法
Application Summary AI generated
This standard specifies the method for determining the apparent relative density of coal, which is the ratio of the mass of a coal sample to the mass of an equal volume of water at a specified temperature. It is applied in the coal mining and processing industries for resource evaluation, reserve calculations, and quality control, particularly when assessing coal for combustion, coking, or conversion processes. The method is used in laboratory testing contexts to ensure accurate measurement of coal density for commercial and technical specifications.
