Scope

This part of GB/T 3286 specifies the determination of sulfur content by tube furnace combustion-potassium iodate titration method, high-frequency combustion infrared absorption method and barium sulfate gravimetric method. This section applies to the determination of sulfur content in limestone and dolomite, and the determination of sulfur content in metallurgical lime. The measurement range (mass fraction) of tube furnace combustion-potassium iodate titration method and high-frequency combustion infrared absorption method is 0.01%~0.5%; the measurement range (mass fraction) of barium sulfate gravimetric method is that the sulfur content is greater than or equal to 0.10%; appendix B tube furnace combustion - iodine titration measurement range (mass fraction) sulfur content is not less than 0.01%.
