This edition includes the following significant technical changes with respect to the previous edition:
— insertion of a third class of electrical steels for magnetic domain refined high permeability grades;
— introduction of the Single Sheet Testing (SST) method as reference measurement method for this
third class of material together with a conversion factor for transposition of the SST measurement
results to the Epstein measurement results;
— update of the electrical steel range to take account of the current offers and demands of grades.
Any feedback and questions on this document should be directed to the users’ national standards body.
A complete listing of these bodies can be found on the CEN website.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the

Through its sub-committee SC 8 “Steel sheet and strip for electrical applications” (secretariat: DIN).
Introduction
The insertion of a third class of electrical steels for magnetic domain refined high permeability grades is
the main reason of this revision. Most of the technologies of magnetic domain refinement result in
material that does not withstand the stress relief annealing after cutting without changing the magnetic
properties (i.e. the specific total loss). In the case of this material, the Epstein method according to
EN 60404-2, requiring the annealing of the Epstein strip samples, is not suitable. Therefore, the Single
Sheet Tester (SST) method specified in IEC 60404-3 is employed.
The introduction of the SST as the reference measurement method for these magnetic domain refined
high permeability grades was preceded by intense discussions within IEC/TC 68.
The specific total loss measured by use of the SST specified in IEC 60404-3 tends to be larger than the
value measured by the use of Epstein frame in accordance with EN 60404-2. The magnetic polarization
at H = 800 A/m measured by use of the SST tends to be a little lower than the value measured by the use
of Epstein frame.
The significant difference between Epstein and SST loss results made it necessary to introduce a
Conversion Factor, F , applied to the SST results. This Conversion Factor is to create continuity in the
c
quality characteristics ratio of conventional grain-oriented electrical steel grades and of high
permeability grades (Epstein related loss values) to the magnetic domain refined high permeability
grades (SST related loss values), particularly over the transition zone between these grades. Otherwise,
it might be confusing to the users of this specification standard that the higher quality materials
measured by the SST method are listed with seemingly higher values of the specific total loss, compared
with the lower Epstein values measured on the lower quality grades.
Considerations of the widely spread grades of grain-oriented electrical steel led to the consented value
of F = 0,925 to be applied to the loss values at 1,7 T measured by the SST method.
c
The magnetic polarization for H = 800 A/m is the value taken from the SST measurement without
conversion to an equivalent Epstein value.
Consequently, the magnetic domain refined high permeability grades have been listed in a new
Table 3 as a new class of grain-oriented electrical steel strip and sheet.
