4.1 Classification
The steel grades covered by this European Standard are classified according to the value of maximum specific
total loss in watts per kilogram and according to the nominal thickness of the material (0,23 mm, 0,27 mm, 0,30
mm, 0,35 mm).
4.2 Designation
4.2.1 For the steel grades covered by this European Standard, the steel names are allocated in accordance with

4.2.2 The steel names comprise the following in the order given :
a) capital letter M for electrical steel,
b) a number of one hundred times the specified value of maximum specific total loss at 50 Hz, in watts per
kilogram corresponding to the nominal product thickness, at 1,7 T,
c) one hundred times the nominal thickness of the product, in millimetres,

S for conventional grain oriented products ;
P for high permeability grain oriented products.

EN 10107:2005 (E)
6.2 Form of supply
The material is supplied in bundles in the case of sheets and in coils in the case of strip.
The mass of bundles of sheets or of coils shall be agreed at the time of enquiry and order.
The recommended value for the internal diameter of coils is approximately 508 mm.
Sheets which 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 manner 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 the removal of 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 the further processing of the
material.
6.3 Delivery condition
Grain-oriented products are usually supplied with an insulating coating on both sides. This coating generally
consists of a so called glass film composed essentially of silicates of magnesium on which has been deposited a
1)
second coating of inorganic constituents such as phosphates, normally as part of a thermal flattening operation .
6.4 Surface condition
2)
The surfaces shall be smooth and clean, free from grease and rust . Dispersed defects such as scratches,
blisters, cracks, etc., are permitted if they are within the limits of the tolerances on thickness and if they are not
detrimental to the correct use of the supplied material.
The insulation coating present on the surface of the material shall be sufficiently adherent so that it does not
become detached during cutting operations or heat treatment under conditions specified by the supplier.
NOTE If the product is to be immersed in a fluid, an agreement, initiated by the purchaser, should be reached to ensure
compatibility between the fluid and the coating.
6.5 Suitability for cutting
The material shall be able to be cut at any point and into the usual shapes thus ensuring accurate working with the
correct cutting tools.
7 Technical requirements
7.1 Magnetic properties
7.1.1 General
The properties defined in 7.1.2 and 7.1.3 are applicable to materials in the delivery conditions defined in 6.3.
7.1.2 Magnetic polarization
1) Other types of coating exist which are used only when particularly specified.
2) Not to be confused with some colouration of the insulating coating inherent in the manufacturing process.
