Application Summary AI generated

This standard specifies three methods for determining sulphur content in limestone and dolomite: pipe furnace combustion with iodic acid potassium titration, high-frequency combustion with infrared absorption, and barium sulfate gravimetry. It is applied in the mining and mineral processing industries for quality control and chemical analysis of these carbonate rocks, which are used as raw materials in cement, steelmaking, glass, and construction. The standard ensures accurate sulphur measurement to assess material suitability and environmental compliance during production and processing.
