ECISS/TC 20 - Methods of chemical analysis of ferrous products

This EURONORM specifies a method for the determination of calcium in steels by means of flame atomic absorption sptectrometry. The method is applicable to non-alloy and low-alloy steels with calcium contents greater than 0,0002 % (m/m).
NOTE The method has also been successfully applied to a highly alloyed steel with appropriate modification of the calibration solutions to contain the principal alloying elements in concentrations similar to those in the sample to be analysed (see Annex).

This EURONORM specifies a method for the determination of lead in steels by means of flame atomic absorption spectrometry.
The method is applicable to non-alloy and low-alloy steels with lead contents of 0,0003 to 0,5 % (m/m) (see Annex).

This EURONORM specifies a method for the determination of nickel in steels and irons by means of flame atomic absorption spectrometry.
The method is applicable to steels and irons with nickel contents of 0,003 to 2,0 % (m/m).

Specifies principle, reagents, apparatus, sampling, procedure, expression of results and test report. Annex A gives additional information on the international co-operative tests. Annex B represents the precision data graphically.

This EURONORM specifies a gravimetric method for the determination of total carbon in steels and irons after combustion in a stream of oxygen.
The method is applicable to carbon contents equal to or greater then 0,1% (m/m).

Corresponds part 1 (excluding the silicium contents). Specifies principle, reagents, apparatus, sampling, procedure, expression of results and test report. An annex gives additional information on the international co-operative tests.

The method is applicable to nickel contents between 0.5 % (m/m) and 30 % (m/m). Specifies principle, reagents, apparatus, sampling, procedure, expression of results and test report. Annex A gives additional information on the international co-operative tests, and Annex B represents the precision data graphically.

This method is applicable to copper contents between 0.02 % (m/m) and 5 % (m/m). Specifies principle, reagents, apparatus, sampling, procedure, expression of results and test report. Annex A gives additional information on the international co-operative tests. Annex B includes the graphical representation of precision data.

This document is a guideline to carry out the statistical evaluation of data from an inter laboratory test for method validation.
Its purpose is to detail the methodology of ISO 5725-1, -2 and -3:1994 standards for the treatment of registered data in the conditions used within the ECISS/TC 20 working groups.
NOTE   The present document is not a simplification of ISO 5725 standard, which is the only reference document.

This European Standard specifies a flame atomic absorption spectrometric method for the determination of titanium in steel and iron. The method is applicable to alloyed and non-alloyed steel and iron with titanium contents of 0,01% to 1% (m/m).

This document describes the classification, the method of sample preparation for each material, the certification main rules and certificate content of the EURONORM-CRMs.
It also lists the samples' presentation, the corresponding producer's organizations and the distributing sources.

This EURONORM specifies an electrometric titration method for the determination of manganese in steels and iron.
The method is applicable to non-alloy or alloy steels and to irons with manganese contents greater than or equal to 0,5% (m/m).

Introduction and procedures for preparation and classification of EURONORM-CRMs.
