Scope

This standard specifies the determination of sulfur content by barium sulfate gravimetric method and combustion-potassium iodate titration method. This standard applies to the determination of sulfur content in limestone and dolomite, and also applies to the determination of sulfur content in metallurgical lime. The first barium sulfate gravimetric method, the measurement range: the sulfur content is greater than 0.10%; the second combustion-potassium iodate titration method, the measurement range: the sulfur content is 0.01% to 0.50%; Appendix A (standard appendix) combustion-iodine titration method, measuring range: the sulfur content is greater than 0.010%.
