This European Standard specifies cold-rolled non-oriented electrical steel strip and sheet 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 IEC 60404 1:2000, C.2.3.2.1.

Overview

EN 10106:2015 is the CEN European standard for cold rolled non-oriented electrical steel strip and sheet delivered in the fully processed (fully annealed) state. It covers products in nominal thicknesses of 0.35 mm, 0.50 mm, 0.65 mm and 1.00 mm intended for use in the construction of magnetic circuits. The standard defines general requirements, magnetic performance criteria, geometric characteristics and tolerances, technological properties and the inspection/testing regime for ready-to-use electrical steel.

Key Topics

• Product scope and delivery condition
  • Cold-rolled, non-oriented electrical steel supplied in the fully processed (fully annealed) state. Semi-processed material is excluded.
• Classification and designation
  • Grades are classified by maximum specific total loss (W/kg at 50 Hz, 1.5 T) and nominal thickness. Example designation format: M250-35A.
• Magnetic properties
  • Requirements for magnetic polarization, specific total loss and loss anisotropy. Tests referenced to standard magnetic test methods.
• Geometric characteristics & tolerances
  • Thickness, width, length, edge camber, flatness (wave factor) and residual curvature requirements and sampling.
• Technological characteristics
  • Density, stacking factor, number of bends, internal stresses; relevant for lamination, stacking and forming.
• Inspection and testing
  • Sampling, specimen preparation and test methods (magnetic, geometrical and technological) plus retest and complaint procedures.
• Ordering information
  • Purchaser must specify quantity, product type (strip/sheet), EN number, steel name/number, dimensions, coil axis (horizontal/vertical), coil inner diameter (508 mm or 610 mm), mass limits, and inspection type.

Applications

EN 10106 products are used where uniform magnetic performance and predictable processing behaviour are critical:

• Electric motor stators and rotors
• Transformers and inductors (small/medium sizes)
• Generators and electromagnetic devices
• Any magnetic circuits requiring non-oriented electrical steel laminations Users: steel producers, laminators, motor and transformer manufacturers, procurement/specification engineers and test laboratories.

Related Standards

• IEC 60404-1 (correspondence C.2.3.2.1)
• EN 10251, EN 10280 (geometrical & magnetic measurement methods)
• EN 60404-2, EN 60404-13 (magnetic testing & stacking factor)
• EN 10021, EN 10204 (general delivery and inspection documents)

EN 10106 aids specification clarity for manufacturers and buyers, ensuring consistent magnetic performance, dimensional tolerances and inspection practices for fully processed non‑oriented electrical steel.
