This part of IEC 60404 defines the grades of cold-rolled non-oriented electrical steel sheet and strip 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, and technological characteristics, as well as the inspection procedure.
NOTE - This standard gives in annex A the magnetic properties at 50 Hz and 60 Hz of electrical sheet and strip of thickness 0,47 mm.
This 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 clause C21 of IEC 60404-1.
