This section drafted in accordance with GB/T 1.1-2009 given rules. This Part replaces GB/T 3286.7-1998 "limestone, dolomite Chemical analysis methods Determination of sulfur content", and GB/T 3286.7- Compared to 1998, the main technical changes are as follows. --- The standard name changed to "limestone, dolomite Chemical analysis methods - Part 7. Determination of sulfur content tube furnace combustion - iodate Potassium titration method, high-frequency combustion infrared absorption method and barium sulfate gravimetric method "; --- Increased frequency combustion infrared absorption method; --- Original barium sulfate gravimetric method, a tube furnace combustion - potassium iodate titration method in the standard order of the exchange; --- Barium sulfate gravimetric method and tube furnace combustion - iodometric titration measurement range, respectively, greater than or equal to 0.10% and 0.01% ~ 0.5%; --- Normative references canceled the reference standard reign, and adds some reference standards; --- Tube furnace combustion - potassium iodate titration method increases calculated using the same reference material/titre standard sample method; --- Carried out jointly between laboratory precision test statistics obtained by the repeatability limit (r) and reproducibility limit R instead of "allowable difference."
