Introduction
ln accordance with the definition in ISO Guide 30, Amendment 1:2008, a Certified Reference Material (CRM)
as 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 organization on behalf of the Co-ordinating Committee
(COCOR) of ECISS after approval by the participating laboratories and all the producing organizations:
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.
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 organizations 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
kSIST-TP FprCEN/TR 10317:2014
FprCEN/TR 10317:2014 (E)
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 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 100 kg. This is blended in a cylindrical
or cube shaped mixer before certification analysis.
Samples supplied in disc form are prepared from the most homogeneous parts of the rolled or forged material.
If the finely divided sample is prepared by atomisation of the liquid metal, disc samples may be prepared by
hot isostatic pressing of the powder. This process has been used where it is difficult to obtain homogeneous
solid material for spectroscopic analysis by casting or forging.
In all cases it is verified that the solid and finely divided samples are identical in chemical composition.
3.1.2 Pig irons and cast irons
The metal in the form of solid or hollow cylinders is descaled; its homogeneity is verified and then it is dry
machined on a lathe. The turnings are separated into three sieve fractions, the dust being continually drawn
off. Only the middle fraction is retained and homogenized before certification analysis and bottling.
Some iron samples are produced by crushing the solid material or by atomisation of the liquid metal.
3.1.3 Ferro-alloys
A bulk supply (usually more than 100 kg) of ferro-alloy material taken from production is crushed and ground
to a suitable particle size.
As there is the possibility with such material for the composition to vary with particle size, homogeneity checks
are carried out on several size fractions of the bulk material.
Only those size fractions which are sufficiently similar to each other with respect to chemical composition are
selected, and these are blended in a cube shaped or cylindrical mixer made of stainless steel to produce the
homogeneous product to be used to produce the CRM.
3.2 EURONORM-CRMs of non-metallic materials
3.2.1 Ores, Concentrates, Sinters and Miscellaneous Materials: Additives and Refractories
The material is selected in such a way that it has the best composition and storage properties. After drying,
crushing and grinding, it is screened to a suitable particle size and blended in a cube shaped or cylindrical
mixer made of stainless steel.
kSIST-TP FprCEN/TR 10317:2014
FprCEN/TR 10317:2014 (E)
The bulk sample is carefully stored in airtight containers. Where necessary a moisture absorber is placed
inside the container.
Throughout the whole preparation process the homogeneity is verified.
3.2.2 By-products, such as slags, dusts and similar materials
The same rules apply for the preparation of the samples as for materials listed under 3.2.1. The certification
analysis can only be carried out after a long stabilization period, during which the composition is verified by
means of numerous check analyses.
4 Certification
4.1 Main rules
The certification of these EURONORM-CRMs is performed following the established guidelines in ISO Guides
30, 31, 34 and 35 and the standard ISO 11459 (see Bibliography).
Chemical characterization of a candidate material is carried out in a certification interlaboratory comparison
with approximately 20 laboratories from industry and research in Europe.
Each laboratory is requested to analyse the elements to be determined four times under repeatability
conditions but on separate portions of the sample, using a suitable analytical method of its choice.
A statistical evaluation is carried out on all the individual values obtained for

1 Scope
This Technical Report 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, 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 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 %.
