ISO/TC 155/WG 6 - Revision of Carbon and Sulfur determination standards

This document specifies an infrared absorption method after combustion in an induction furnace for the determination of the carbon content in ferronickels in the range of 0,004 % to 2,5 %. The method is applicable to normal production operations. It uses commercially available equipment, which is calibrated using steel and/or ferronickel certified reference materials (CRMs).

This document specifies an infrared absorption method after combustion in an induction furnace for the determination of the sulfur content in ferronickels in the range of 0,002 % to 0,12 %. The method is applicable to normal production operations. It uses commercially available equipment, which is calibrated using steel and/or ferronickel certified reference materials (CRMs).
