This document specifies the technical delivery requirements for the various forms of ferronickel
(ingots, pieces and shot) usually supplied for steel making and foundry use.

ISO 5446:2017 specifies requirements and conditions of delivery for ferromanganese usually supplied for steelmaking and foundry use.

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).

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).

ISO 6467:2018 specifies a potentiometric method for the determination of the vanadium content of ferrovanadium. The method is applicable to vanadium contents between 35,0 % and 85,0 % (mass fraction) in ferrovanadium.

ISO 5446:2017 specifies requirements and conditions of delivery for ferromanganese usually supplied for steelmaking and foundry use.

Measurement of GHG emissions in ferroalloy industry by a verified determination method. This standard is result of the acceptance of M/478 whereby six standards will be developed: one general standard and five sector-specific.

This International Standard 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).

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).

This International Standard specifies a flame atomic absorption spectrometric method for the determination of the Cobalt content of ferronickel in the range 0,025 to 2,5 % (mlm).

This International Standard specifies a gravimetric method for the determination of the nicke1 content of ferronickel in the range 15 to 60 % Hm).

This International Standard specifies a gravimetric method for the determination of Silicon in ferronickel in the range 0,2 to 4,0 % b7?lmL

This International Standard specifies a method for sampling of  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. As agreed between the purchaser and the supplier, a choice is to be made between two procedures:
- The first procedure can be applied at the procedur,s  plant during casting (description in clauses 3 and 5).
- The second procedure can be applied to lots as delivered at th...view more
