Foreword
This document (CEN/TR 10317:2013) has been prepared by Technical Committee 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 [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights.
This document supersedes CEN/TR 10317:2009.
In comparison with the previous edition of CEN/TR 10317:2009, the following significant technical changes
were made:
 Clause 2, definition of Certified Reference Material;
 in 5.1, change of the procedure how to carry out the four required determination.
Introduction
ln accordance with the definition in ISO Guide 30, Amendment 1:2008, a Certified Reference Material (CRM)
described in this CEN Technical Report is a "reference material 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 organisation on behalf of the Co-ordinating Committee
(COCOR) of ECISS after approval by the participating laboratories and all the producing organisations:
a) France:
1) ArcelorMittal Maizières [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) BAM Bundesanstalt für Materialforschung und -prüfung,
2) Max-Planck-Institut für Eisenforschung (MPI),
3) Stahlinstitut VDEh;
c) Nordic Countries: Nordic CRM Working Group, (NCRMWG) comprising:
1) Swerea KIMAB [former Swedish Institute for Metals Research (SIMR)],
2) Jernkontoret;
d) United Kingdom: Bureau of Analysed Samples Limited (BAS).
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 Technical Report describes the classification, method of sample preparation, certification main rules and
certificate content of the EURONORM-CRMs.
It also lists the sample presentation of the corresponding producer's organisations and the distributing
sources.
2 Classification of EURONORM-CRMs
EURONORM-CRMs, prepared under the auspices of ECISS, 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 mass content 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 0,10 %;
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 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 a 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 generatio
