BS IEC 60404-8-5 defines the grades of electrical steel strips and sheets 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.
BS IEC 60404-8-5 applies to electrical steel strips and sheets intended for the construction of poles and rims of rotating electrical machines.
BS IEC 60404-8-5 on magnetic materials applied for the following:
Steel displays ferromagnetic properties as it is derived from iron.
BS IEC 60404-8-5 groups the steel grades into two classes according to their manufacturing process:
As a manufacturer, compliance with BS IEC 60404-8-5 can ensure that critical properties such as low core losses, high flux density and permeabilities are retained so as to meet the specific needs of the applications.
Best industry guidance on magnetic properties of steel as per BS IEC 60404-8-5 can be beneficial in making the right selection of materials used for efficient energy generation, transmission and consumption.
BS IEC 60404-8-5:2020 cancels and replaces the first edition published in 1989. The main changes compared to the previous edition are as follows
