Foreword

This Part replaces GB/T 8704.3-1997 "determination of sulfur content for chemical analysis of ferrovanadium The infrared absorption method and combustion - neutralization titration method." This portion of the GB/T 8704.3-1997 comparison, the main changes are. --- The method of one of the sample weight 0.500g, 0.200g two tranches adjusted to a file 0.200g; --- The method of one of the iron from the flux amount was adjusted to 0.50g 0.20g; --- The method of one of the first, second gear allows for the consolidation difference sulfur content of 0.005% to 0.015%, 0.002% allowable difference; --- The second method of determination by the scope of < 0.120% to 0.005% and 0.120%. This part is proposed by the China Iron and Steel Association. This part of pig iron and ferroalloy by the National Standardization Technical Committee. This section is drafted.
