This Technical Specification describes the determination of S, Cl, F and Br in solid recovered fuels of various origin and composition after combustion in oxygen atmosphere. S and Cl can be alternatively determined by direct automatic analysis (see Bibliography for examples of available methods). Other methods could also be used provided that it is demonstrated that they give the same results.
This method is applicable for concentrations over 0,025 g/kg, depending on the element and on the determination technique.
Insoluble halides and sulphate present in the original sample or produced during the combustion step are not completely determined by these methods.
This Technical Specification provides recommendations concerning standardised methods for determination of halides and sulphate in the solution obtained after combustion.
