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.

This European Standard provides a harmonized methodology for calculating GHG emissions from the ferro-alloys industry based on the mass balance approach . It also provides key performance indicators over time of ferro-alloys plants. It addresses the following direct and indirect sources of GHG:
- Scope 1 - Direct GHG emissions from sources that are owned or controlled by the company, such as emissions result from the following sources:
- smelting (reduction) process;
- decomposition of carbonates inside the furnace;
- auxiliaries operation related to the smelting operation (i.e. aggregates, drying processes, heating of ladles, etc.).
- Scope 2 - Indirect GHG emissions from:
- the generation of purchased electricity consumed in the company’s owned or controlled equipment.
This European Standard is to be used in conjunction with FprEN 19694-1, which contains generic, overall requirements, definitions and rules applicable to the determination of GHG emissions for all energy-intensive sectors, provides common methodological issues and defines the details for applying the rules. The application of this standard to the sector-specific standards ensures accuracy, precision and reproducibility of the results and is for this reason a normative reference standard. The requirements of these standards do not supersede legislative requirements.

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).
