This document specifies a spectrophotometric method for the determination of the phosphorus content in nickel, ferronickels and nickel alloys between 0,000 5 % (by mass) and 0,05 % (by mass). Arsenic, chromium, hafnium, niobium, silicon, tantalum, titanium and tungsten interfere, but the interferences can be avoided by complexation or volatilization (for chromium). The lowest phosphorus content [0,000 5 % (by mass)] can only be reached in samples with low contents of these interfering 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 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 the buyer,s premises (description in clauses 4 and 5). It includes two alternatives for sample taking (drilling and milling).
Each party is entitled to participate in ( or be represented at) sampling operations.
