CEN/TC 459/SC 8/WG 1 - Measurement of the coating properties of non­oriented electrical steel

This document describes the mechanical testing methods, relevant for self-bonding coating assemblies with non-oriented electrical steels. In particular, it describes the mechanical testing methods, sample preparation, calibration methods, necessary to obtain reliable results that can be considered a reference for quality evaluation.
This document applies only to self-bonding coatings of non-oriented electrical steels.

This document defines the grades of electrical steel strip and sheet with specified mechanical properties and magnetic polarisation. It specifies general requirements, mechanical properties, magnetic polarisation, geometric characteristics, tolerances and technological characteristics, as well as inspection procedures.
This document applies to electrical steel strip and sheet for the construction of poles and rims of rotating electrical machines.
The grades are grouped into two classes according to their manufacturing process:
-   hot-rolled grades;
-   cold-rolled grades.
NOTE   These materials correspond to EN 60404-1:2018, D.2.
