Steels and cast irons - Determination of chromium content - Flame atomic absorption spectrometric method (FAAS)
EN 10188:2024

This document specifies a flame atomic absorption spectrometric method (FAAS) for the determination of chromium content in steels and cast irons.
The method is applicable to non-alloy and low-alloy steels and cast irons with chromium contents between 0,002 % (by mass) to 2,0 % (by mass).
The method can be adapted to lower or higher chromium contents by changing the test portion or the dilution process, provided the criteria in 6.3.2 and 6.3.3 are still met.

These Directives require the characterization of these materials for Cadmium (Cd), hexavalent chromium (Cr (VI)), mercury (Hg), Lead (Pb), polybrominated biphenyls (PBB), polybrominated diphenyl ethers (PBDE) and the four phthalates DEHP, BBP DBP and DIBP. Nevertheless, the Directives do not reflect the correspondence between these elements/compounds and the normal composition of each material concerned. In other words, for every material there is an obligation to determine all the compounds listed, independently of the relevance of such controls.

Analysis of steels and irons - Internal laboratory procedure for checking the accuracy of an analytical method by using Certified Reference Materials
CEN/TR 10350:2013

The present statistical procedure describes how to check results for absence of bias by comparison of these analytical results with those obtained during the certification of CRMs. If the resulting data confirm the absence of bias, the method may be considered accurate when applied to all steels and irons whose composition ranges are adequately covered or bounded by the CRMs used. The resulting data give also an estimate of the repeatability and/or the intermediate precision ("intralaboratory reproducibility") for the CRMs used. The comparison of these analytical data with the repeatability data obtained during the certification may also be performed depending on the strict purpose of the method under consideration. For the purpose of this Technical Report, the use of existing CRMs is essential for the assessment of the trueness, but it may be only indicative for the other statistical data.

Calculation method of carbon dioxide emission intensity from iron and steel production — Part 2: Steel plant with electric arc furnace (EAF)

ISO 14404-2:2013 specifies calculation methods which companies using EAF to manufacture steel can use to evaluate the total annual carbon dioxide (CO2) emissions and the emission factor of CO2 per unit of steel production of the entire steel production process. ISO 14404-2:2013 is applied to the plants that produce mainly carbon steel. It includes boundary definition, material and energy flow definition, and emission factor of CO2. Besides direct source import to the boundary, upstream and credit concept is applied to exhibit the plant CO2 intensity. ISO 14404-2:2013 supports the steel producer to establish CO2 emissions attributable to a site. ISO 14404-2:2013 cannot be used to calculate benchmarks or to compare CO2 intensities of production processes that are operated inside the site.
