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).

ISO 8049:2016 defines a method of sampling for analysis of ferronickel lots in the form of shot as specified in ISO 6501 in those cases where lots are constituted either heat by heat or by taking from blended stock.
The purpose is to determine the contents of the various elements
- either from slugs by physical analysis methods (such as X-ray fluorescence or emission spectral analysis), or
- from chips by dry methods (carbon, sulfur) or chemical analysis (other elements).

Applies to ferronickel lots in ingot or piece form with a view to obtaining a representative laboratory sample for the determination of the chemical composition of the lot. A choice is to be made between a first procedure that can be applied at the producer's plant during casting or a second procedure that can be applied to lots as delivered at the buyer's premises. Includes two alternatives for sample taking (drilling and milling). Each party is entitled to participate in sampling operations.
