1 Scope
This European Standard specifies cold-rolled non-oriented electrical steel sheet and strip in nominal thicknesses
of 0,35 mm, 0,50 mm, 0,65 mm and 1,00 mm. In particular, it specifies general requirements, the magnetic
properties, geometric characteristics and tolerances, technological characteristics as well as the inspection
procedure.
This European Standard applies to materials supplied in the fully annealed condition intended for the
construction of magnetic circuits. It does not apply to semi-processed material.
These magnetic materials correspond to C.2.3.2.1 of IEC 60404-1:2000.

4 Classification and designation
4.1 Classification
The grades covered by this European Standard are classified according to the value of the maximum specific
total loss in watts per kilogram and according to the nominal thickness of the material (0,35 mm, 0,50 mm,
0,65 mm and 1,00 mm).
4.2 Designation
For the steel grades covered by this European Standard, the steel names are allocated in accordance with EN
10027-1. The steel numbers are allocated in accordance with EN 10027-2.
The steel name is comprised of the following in the order given:
a) capital letter M for electrical steel;
b) number of one hundred times the specified value of maximum specific total loss at 50 Hz, in watts per
kilogram and corresponding to the nominal product thickness, at 1,5 T;
c) one hundred times the nominal thickness of the material, in millimetres;
d) characteristic letter A for non-oriented electrical sheet or strip supplied in the fully processed state.
EXAMPLE Non-oriented electrical steel sheet or strip with a maximum specific total loss at 1,5 T of 2,50 W/kg at 50 Hz,
a nominal thickness of 0,35 mm, supplied in the fully processed state: M250-35A

specification of this standard (see 5.1).
5.3 Example of an order
18 t strip with 0,35 mm thickness in accordance with EN 10106, made of steel grade M270-35A, delivered in
coils with a width of 1 000 mm and a maximum mass of 3 500 kg, vertical coil axis (v), with specific inspection,
inspection report 3.1 in accordance with EN 10204:
18 t – strip – EN 10106 – M270-35A – 1000 mm – max. 3500 kg – v – 3.1
6 General requirements
6.1 Production process
The production process of the steel and its chemical composition are left to the discretion of the manufacturer.
6.2 Form of supply
For sheets the material is supplied in bundles and for strip the material is supplied in coils.
The mass of bundles of sheets or the mass and/or the external diameter of coils shall be agreed at the time of
enquiry and order.
The mass of the package unit shall be agreed at the time of enquiry and order.
The recommended value for the internal diameter of coils is 508 mm or 610 mm.
The direction of coils, horizontal (h) or vertical (v), shall be agreed at the time of enquiry and order.
Sheets that make up each bundle shall be stacked so that the side faces are substantially flat and
approximately perpendicular to the top face.
Strip shall be of constant width and wound in such a way that the edges are superimposed in a regular manner
and that the side faces of the coil are substantially flat. Coils shall be sufficiently tightly wound so that they do
not collapse under their own weight.
Strip may exhibit welds resulting from removing defective zones if agreed at the time of enquiry and order. If
necessary the marking of welds may be agreed at the time of enquiry and order. For coils containing welds,
each part of the strip shall be of the same grade.
The edges of parts welded together shall not be so much out of alignment as to affect further processing of
the material.

6.3 Delivery condition
The material may be supplied either without insulation or with insulation on one or both sides in accordance
with EN 10342. lf the material is supplied with insulation, the nature of the insulation, its thickness and
properties, the stacking factor and their verification shall be agreed at the time of enquiry and order (see
Annex A, Option 2) and in accordance with the values stated in Annex D, Table D.1.
6.4 Surface condition

1)
The surfaces shall be smooth and clean, free from grease and rust . Dispersed defects such as scratches,
blisters, cracks, etc. are permitted if the products are within the tolerances and if these defects are not
detrimental to the correct use of the supplied material.
When an insulation coating is present on the surface of the material, it shall be sufficiently adherent so that the
coating does not become detached during cutting operations. During the alternating bend test (see 8.4.3.2),
the coating shall not be detached after a bend of 90°. If the coating becomes detached during the test, the
piece from which the sample was taken shall be subjected to a shearing test. During this test, it shall not be
admissible for large pieces of the coating to become detached; however, slight chipping of this coating at the
shearing edges shall be tolerated.
6.5 Suitability for cutting
The material shall be able to be cut or punched at any point and in the usual shapes, thus ensuring accurate
working with the correct cutting tools.

7.1.1 General
The properties defined in 7.1.2 to 7.1.4 are applicable to products in the delivery conditions defined in 6.3.

7.1.3 Specific total loss
The specified values of maximum specific total loss shall be as given in Table 1. They reflect the aged
