European foreword
This document (CEN/TR 10317:2020) has been prepared by Technical Committee CEN/TC 459/SC 2
(former ECISS/TC 102) “Methods of chemical analysis for iron and steel”, the secretariat of which is
held by SIS.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes CEN/TR 10317:2014.
In comparison with the previous edition, CEN/TR 10317:2014, the following technical modifications
have been made:
— title changed;
— deletion of all references to COCOR and ECISS;
— updating of the addresses of some of the producers;
— Bibliography updated.
Introduction
In accordance with the definition in ISO Guide 30, a Certified Reference Material (CRM) as described in
this document is a “reference material (RM) characterized by a metrologically valid procedure for one
or more specified properties, accompanied by a certificate that provides the value of the specified
property, its associated uncertainty, and a statement of metrological traceability”.
Furthermore, it is accompanied by a certificate issued by the producing organization, after approval by
the participating laboratories and all the producing organizations listed below:
a) France:
1) ArcelorMittal Maizières Research SA (AMMZ) [former Institut de Recherches de la Sidérurgie
Française (IRSID)],
2) Centre Technique des Industries de la Fonderie (CTIF);
b) Germany: Iron and Steel CRM Working Group (AGZRM) comprising:
1) Bundesanstalt für Materialforschung und -prüfung (BAM),
2) Max-Planck-Institut für Eisenforschung (MPI),
3) Stahlinstitut VDEh;
c) Nordic Countries: Nordic CRM Working Group, (NCRMWG) comprising:
1) Oy Narema AB,
2) Jernkontoret.
NOTE Bureau of Analysed Samples Ltd (BAS) – United Kingdom – was a member of the EURONORM-CRM
Producer's Group from 1975 until 2013.
Since 1968, EURONORM-CRMs have been analysed by laboratories in most countries in the European
Union (EU) or former European Community (EC).
Pending their eventual replacement by EURONORM-CRMs, a number of former national CRMs
prepared, analysed and certified by laboratories in Germany, France and the United Kingdom
respectively, were accepted as EURONORM-CRMs after their accuracy had been checked by other
European laboratories. This procedure ceased in 1990.
1 Scope
This document describes the classification, method of sample preparation, certification main rules and
certificate content of the EURONORM-CRMs.
It also details the sample presentation of the various producers' organizations and the distributing
sources.
2 Classification of EURONORM-CRMs
EURONORM-CRMs, are classified into two main groups:
— cast and wrought materials: irons, steels, special alloys and ferro-alloys;
— non-metallic materials: raw materials (ores, concentrates, additives and refractories) and by-
products (slags, dusts and similar materials).
Besides this first generic classification, EURONORM-CRMs are grouped into the following categories:
a) From 001 to 099 – High purity irons and unalloyed steels
Normally no element has a content (mass fraction) greater than the limit values in the following
list:
1) silicon, limit value 1,0 %;
2) manganese, limit value 1,5 %;
3) chromium and nickel, limit value for each 0,5 %;
4) cobalt, copper and tungsten, limit value for each 0,3 %;
5) other elements, limit value for each 0,1 %;
6) boron, carbon, phosphorus, lead and sulphur, no limit value.
b) From 101 to 199 – Low alloy steels
The content of one or more elements is greater than the limit given for unalloyed steels but none
exceeds 5 %. The sum of these alloying elements remains under 10 %.
c) From 201 – 299 – Highly alloyed steels
The content of one or more elements is greater than 5 % or the sum of all these alloying elements is
at least 10 %. Nevertheless the iron content will normally be greater than 50 %.
d) From 301 to 399 – Special alloys
The iron content is less than 50 %.
e) From 401 to 499 – Pig irons and cast irons
f) From 501 to 599 – Ferro-alloys
g) From 601 to 699 – Ores, concentrates, sinters and miscellaneous materials
h) From 701 to 799 – Additives and refractories
i) From 801 to 899 – By-products, such as slags, dusts and similar materials
The expression “-1” after a CRM number refers to the first issue of this CRM and “-2”, “-3”, etc. refer to
replacement CRMs of generally similar composition, but not to a further bottling of the original CRM.
NOTE This classification is used as a simple and convenient method of differentiating between samples of
different types of materials. It has no other objective and does not replace existing European or International
product specifications for metallic materials.
3 Preparation of the samples
3.1 EURONORM-CRMs of cast and wrought materials
3.1.1 High purity irons, steels and special alloys
The material is obtained as cylindrical, square or rectangular billets or slabs. After the homogeneity has
been verified, it is machined dry (avoiding excessive heat generation) on a suitable lathe or milling
machine in order to produce short chips; the chips are screened so that the fines can be removed. Some
steel samples are produced by atomisation of the liquid metal.
The whole preparation process provides a batch of generally more than
