CEN/SS M14 - Nickel

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.

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.

Applies to cobalt contents in the range 0,025 to 2,5 % (m/m). Specifies principle, reagents, apparatus, sampling and samples, procedure, expression on results, special cases and test report.

Applies to nickel contents in the range 15 to 60 % (m/m). Specifies principle, reagents, apparatus and samples, procedure, expression of results and test report. Annex A is provided for the determination of nickel in combined filtrates by atomic absorption spectrometry. Annex B gives a statistical report of interlaboratory tests.

Specifies a method for the determination of silicon in ferronickel in the range 0,2 to 4,0 % (m/m). Gives principle, reagents, apparatus, sampling and samples, procedure, expression of results and test report.

Specifies the technical delivery requirements for various forms of ferronickel (ingots, pieces, shot) usually delivered to foundries and steel-melting shops. Specifies furthermore definition, information for ordering, control, dispatch and storage.

Applies to 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 blendes stock. The purpose is to determine the contents of the various elements either from slugs by physical analysis methods or from chips by dry methods or chemical analysis.

Applies to the determination of sulfur content of nickel and ferronickel in the range 0,001 to 0,3 % (m/m), and of nickel alloys in the range 0,001 to 0,1 % (m/m). Specifies principle, reagents and materials, apparatus, sampling and samples, procedure, expression of results, some notes and test report. Examples of compositions of nickel, ferronickel and nickel alloy are given in annex A.
