Steels - Determination of nitrogen (trace amounts) - Spectrophotometric method
SIST EN 10179:2024

This document specifies a spectrophotometric method for the determination of nitrogen in steels.
The method is primarily intended for the determination of total nitrogen in very low contents in non-alloy steels.
It can be used, however, for any low nitrogen ferrous alloy that is soluble in hydrochloric acid provided that the acid-resistant form of silicon nitride is not present. These highly resistant nitrides have been found only in samples of silicon steels manufactured without aluminium addition and then only in sheet material.
The method is applicable to nitrogen contents from 0,000 5 % (by mass) to 0,005 % (by mass).
The precision data of the present method are given in Annex A.

Steels and cast irons - Determination of chromium content - Flame atomic absorption spectrometric method (FAAS)
SIST 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 factor, provided the criteria in 6.3.2 and 6.3.3 are still met.
The precision data of the present method are given in Annex A.

Guidelines for the preparation of standard routine methods with wavelength-dispersive X-ray fluorescence spectrometry
SIST-TP CEN/TR 10377:2023

X-ray Fluorescence Spectrometry (XRF) has been used for several decades as an important analytical tool for production analysis. XRF is characterised by its speed and high precision over a wide concentration range and since the technique in most cases is used as an relative method the limitations are often connected to the quality of the calibration samples. The technique is well established and most of its physical properties are well known.
