The procedure is applicable to the analysis of all types of water, including sea water and most industrial effluents. A sulfate concentration in the range of 10 mg/l to 5000 mg/l can be determined using the specified test portion. It is possible to determine higher concentrations after dilution of the laboratory sample. Includes principle, reagents, apparatus, sampling and sample preparation, procedure, expression of results, interferences, special cases, notes on procedures and test report.
