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.
