This standard describes a method for the determination of sulfur content in tungsten concentrates. It is applicable to the determination of sulfur content in tungsten concentrates and contains two methods: high-frequency induction infrared absorption method and combustion-iodometry method. Method 1 is applicable to the determination in the range of 0.10% to 4.00%, and Method 2 is applicable to the determination in the range of 1.00% to 10.00%.
