Magnetic materials - Part 8 5: Specifications for individual materials - Electrical steel strip and sheet with specified properties and magnetic polarization
IEC 60404-8-5:2020+AMD1:2026 CSV defines the grades of electrical steel strip and sheet with specified mechanical properties and magnetic polarization. In particular, it gives general requirements, mechanical properties, magnetic polarization, geometric characteristics, tolerances and technological characteristics, as well as inspection procedures.
This document applies to electrical steel strip and sheet intended for the construction of poles and rims of rotating electrical machines.
The grades are grouped into two classes according to their manufacturing process:
They correspond to Class D21 of IEC 60404-1.
