Overview
EN 10107:2022 is the CEN European standard that defines grain-oriented electrical steel strip and sheet delivered in the fully processed (final annealed) state. It applies to Goss‑textured, grain‑oriented electrical steels supplied as coils or sheets intended for the construction of magnetic circuits (e.g., transformer cores). The standard covers nominal thicknesses of 0.20 mm, 0.23 mm, 0.27 mm, 0.30 mm and 0.35 mm, and groups grades into three classes: conventional, high permeability, and magnetic domain refined high permeability (corresponding to Class C22 of IEC 60404‑1).
Key topics and technical requirements
- Grade classification and designation: Steel names follow the Mxxx‑yyS/P/R format (example: M120‑30S), where loss value, nominal thickness and grade type are encoded.
- Magnetic properties: Specifies measurement methods and acceptance levels for specific total loss (at 1.7 T, 50 Hz) and magnetic polarization (H = 800 A/m).
- Conventional and high‑permeability grades are linked to the Epstein frame method (EN 60404‑2).
- Magnetic domain refined grades use the Single Sheet Tester (SST) method (IEC 60404‑3) as reference; a conversion factor F = 0.925 is applied to SST loss results at 1.7 T to align with Epstein‑based values.
- Geometric characteristics & tolerances: Defines nominal thicknesses, widths, coil/sheet dimensions, flatness attributes (edge camber, edge wave, residual curvature) and tolerances (see clauses on geometric characteristics).
- Technological characteristics: Includes surface condition, suitability for cutting, insulation coating resistance, and behavior in forming/bending tests.
- Inspection and testing: Requirements for sampling, specimen preparation, test methods (Epstein, SST, insulation resistance, resistivity, stacking factor) and retest procedures.
- Delivery condition: Final annealed condition; options and purchaser-specified requirements (weld permissibility, coil mass limits, acceptance unit, test temperature, etc.).
Applications and who uses EN 10107:2022
- Transformer and inductor manufacturers selecting core material for low loss and high permeability.
- Steel producers and mill quality teams to specify production, surface treatment and testing for grain‑oriented electrical steel.
- Procurement and specification engineers to prepare orders that include mandatory data (steel grade, dimensions, inspection level).
- Test laboratories and quality inspectors performing Epstein or SST measurements and interpreting results (including SST→Epstein conversion).
- Design engineers assessing material suitability for magnetic circuits where loss, permeability and formability are critical.

North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Türkiye and the
United Kingdom.
Through its sub-committee SC 8 “Steel sheet and strip for electrical applications” (secretariat: DIN).
Introduction
The insertion of a third class of electrical steels for magnetic domain refined high permeability grades is
the main reason of this revision. Most of the technologies of magnetic domain refinement result in
material that does not withstand the stress relief annealing after cutting without changing the magnetic
properties (i.e. the specific total loss). In the case of this material, the Epstein method according to
EN 60404-2, requiring the annealing of the Epstein strip samples, is not suitable. Therefore, the Single
Sheet Tester (SST) method specified in IEC 60404-3 is employed.
The introduction of the SST as the reference measurement method for these magnetic domain refined
high permeability grades was preceded by intense discussions within IEC/TC 68.
The specific total loss measured by use of the SST specified in IEC 60404-3 tends to be larger than the
value measured by the use of Epstein frame in accordance with EN 60404-2. The magnetic polarization
at H = 800 A/m measured by use of the SST tends to be a little lower than the value measured by the use
of Epstein frame.
The significant difference between Epstein and SST loss results made it necessary to introduce a
Conversion Factor, F , applied to the SST results. This Conversion Factor is to create continuity in the
c
quality characteristics ratio of conventional grain-oriented electrical steel grades and of high
permeability grades (Epstein related loss values) to the magnetic domain refined high permeability
grades (SST related loss values), particularly over the transition zone between these grades. Otherwise,
it might be confusing to the users of this specification standard that the higher quality materials
measured by the SST method are listed with seemingly higher values of the specific total loss, compared
with the lower Epstein values measured on the lower quality grades.
Considerations of the widely spread grades of grain-oriented electrical steel led to the consented value
of F = 0,925 to be applied to the loss values at 1,7 T measured by the SST method.
c
The magnetic polarization for H = 800 A/m is the value taken from the SST measurement without
conversion to an equivalent Epstein value.
Consequently, the magnetic domain refined high permeability grades have been listed in a new
Table 3 as a new class of grain-oriented electrical steel strip and sheet.

Son champ d'application est clairement défini, spécifiant les classes d'acier pour des épaisseurs nominales de 0,20 mm, 0,23 mm, 0,27 mm, 0,30 mm et 0,35 mm. Cette précision permet aux fabricants et aux utilisateurs de mieux comprendre les spécifications et d'assurer une qualité constante dans leurs produits. L'une des forces majeures de cette norme est son approche exhaustive des exigences générales, des propriétés magnétiques, des caractéristiques géométriques, des tolérances et des caractéristiques technologiques, ainsi que des procédures d'inspection. Cela garantit non seulement que les matériaux répondent aux attentes en matière de performance, mais aussi que les processus de fabrication respectent des critères stricts de qualité. En outre, la classification des grades en trois catégories – grades conventionnels, grades à haute perméabilité et grades à haute perméabilité à domaine magnétique raffiné – souligne son importance dans l'industrie. Cette segmentation permet aux utilisateurs de choisir le type d'acier qui répond le mieux à leurs besoins spécifiques, en fonction des applications visées dans la construction de circuits magnétiques. La conformité avec la norme IEC 60404-1, en particulier avec la classe C22, souligne également la pertinence de la norme SIST EN 10107:2022 dans un contexte international, facilitant ainsi l’harmonisation des produits au niveau mondial. Cette norme est donc essentielle pour les professionnels du secteur, en leur fournissant une base solide pour la sélection et l'utilisation de l'acier électrique orienté au grain, garantissant la fiabilité et l’efficacité des équipements électromagnétiques.
