BS EN ISO 7526:2020 - TC

This standard BS EN ISO 7526:2020 - TC Tracked Changes. Ferronickels. Determination of sulfur content. Infrared absorption method after induction furnace combustion is classified in these ICS categories:

• 77.100 Ferroalloys
• 77.120.40 Nickel, chromium and their alloys

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).
