ISO/TS 18806:2014 specifies two methods (high temperature combustion and bomb combustion) for the determination of chlorine in solid mineral fuels. It is applicable to hard coals, brown coals, coke, and tailings.

The chlorine in the digestion solution can be determined using different methods, e.g. an ion-selective electrode, coulometric or potentiometric titration, spectrophotometry, or ion chromatography. In this Technical Specification, the ion chromatographic separation with conductivity detection is described.

The method is applicable to determine the chlorine content higher than 0,005 per cent mass fraction.
