Solid mineral fuels — Determination of total cadmium content of coal
ISO 15238:2016 specifies a procedure for the determination of the total cadmium content of coal.
This procedure has not been validated with coals that spontaneously ignite. Prior to use with such sample types, users should validate the method.
Solid mineral fuels — Determination of phosphorus content — Reduced molybdophosphate photometric met...
ISO 622:2016 specifies a reduced molybdophosphate photometric method for the determination of the total phosphorus content of hard coal, lignites and coke. Two methods for taking the phosphorus into solution are specified, namely extraction from the coal or coke ash with acid or by repeated oxidation of the coal or coke, by acid, to remove carbonaceous matter.
