This Standard sets out a method for the liberation of the chlorine from coal and coke by high-temperature combustion, and its subsequent determination by titrimetry.NOTE: The presence of residual halogen-bearing organic float-and-sink liquids in coal samples will affect the determination of chlorine.This Standard is applicable to coal and coke containing less than 0.3% chlorine.
