1 Scope
1.1 This European Standard applies to cold rolled narrow strip in coils and cut lengths in thicknesses
up to 10 mm and of widths less than 600 mm, made from low carbon, unalloyed and alloyed steels in
accordance with Table 1.
These products are suitable for cold forming. They are also suitable for surface coating. On the other
hand, they are not suitable for hardening treatment followed by tempering.
1.2 This European Standard does not cover cold rolled flat products for which a separate standard
already exists, particularly the following products:
— cold rolled non-oriented electrical steel sheet and strip delivered in the fully processed state
(EN 10106);
— grain-oriented electrical steel sheet and strip delivered in the fully processed state (EN 10107);
— cold rolled electrical non-alloy and alloy steel sheet and strip delivered in the semi-processed state
(EN 10341);
— cold rolled narrow steel strip for heat treatment (EN 10132-1 to −4);
— cold rolled steel flat products with higher yield strength for cold forming (EN 10268);
— cold rolled low carbon steel flat products for cold forming (EN 10130);
— cold reduced blackplate in coil form for the production of tinplate or electrolytic
chromium/chromium oxide coated steel (EN 10205);
— cold rolled low carbon steel flat products for vitreous enamelling (EN 10209).

3 Terms and definitions
For the purposes of this document, the terms and definitions given in EN 10079 apply.
4 Classification and designation
4.1 This European Standard specifies the grades listed in Table 1. In the case of steel grade DC01, the
deoxidation method shall be left to the manufacturer’s discretion. Steel grades DC03, DC04, DC05, DC06
and DC07 shall be supplied fully killed.
4.2 Products manufactured from these steels may be ordered and supplied in different delivery
conditions (see Table 1) and with different surface characteristics (see 6.4 and Table 2).
4.3 For the purposes of the specifications of this European Standard, the selection of steel grade,
delivery condition and surface characteristics are of the responsibility of the purchaser.
NOTE 1 In case of narrow widths, strip complying with this European Standard can also be wound in layers
and supplied in the form of a bobbin wound coil.
NOTE 2 After uncoiling and shearing, strip can be supplied in cut lengths.
5 Designation
The symbol designation of the steel grades in this European Standard is in accordance with EN 10027-1
and the numerical designation is allocated in accordance with EN 10027-2.
The standard designation consists of the words narrow strip or cut lengths, followed in order by
!reference to European Standard EN 10140:2006 and the nominal dimensions of the product and for
the steel grade":
a) reference to this European Standard, EN 10139;
b) the symbol DC, followed by the grade designation (01, 03, 04, 05, 06 and 07);
c) the symbol for delivery condition (see Table 1);
d) the symbol for surface appearance (MA, MB or MC, see Table 2);
e) the symbol for surface finish where appropriate (RN, RL, RM or RR, see 6.4.3 and Table 2).

EXAMPLE 1 Designation of cold rolled narrow strip, 1,50 mm thick, having a normal tolerance on the nominal
thickness, a width of 200 mm, having a normal tolerance on the nominal width, slit edges (GK) and made from
steel grade DC04, in a lightly skin-passed condition (LC) with a smooth and uniform surface appearance (MB) and
a “matt” surface finish (RM):
Narrow strip EN 10140:2006 ― 1,50 × 200 ― GK
Steel EN 10139 ― DC04 + LC ― MB ― RM
EXAMPLE 2 Designation of cold rolled narrow strip, 2,00 mm thick, having a normal tolerance on the nominal
thickness, a width of 450 mm, having a normal tolerance on the nominal width, slit edges (GK) and made from
steel grade DC03, in the annealed condition (A), with a bright, metallically clean surface appearance (MA) and a
smooth surface finish (RL):
Narrow strip EN 10140:2006 ― 2,00 × 450 ― GK

6 Properties
6.1 Steel making process and chemical composition
6.1.1 The steel making process shall be left to the discretion of the manufacturer.
6.1.2 The chemical composition based on ladle analysis shall be as given in Table 1.
6.2 Choice of properties
The products covered by this European Standard shall comply with the specifications given in Table 1.
If agreed separately, they may be supplied with a special suitability for making a particular part; in this
case, a maximum percentage of processing scrap may be fixed by common agreement and acceptance
tests on the basis of the mechanical properties shall not apply.
6.3 Mechanical and technological properties
6.3.1 The mechanical and technological properties of the products are given in Table 1. These
properties are guaranteed for the periods specified in Table 1 with effect from the date that the
products are made available for delivery. The purchaser shall be informed of this date when the
products are to be made available, with a warning appropriate to the guarantee of mechanical
properties. Storage of grade DC01 products for more than 3 months may cause a change in the
mechanical properties likely to give rise to a reduction in the suitability for forming and drawing.
6.3.2 The usual test for checking the mechanical properties given in Table 1 is the tensile test.
However, if agreed at the time of ordering, hardness values may be specified instead of tensile test
properties, but not both.
6.3.3 The tensile test values shall apply to longitudinal test pieces.
