FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

INTRODUCTION
Fe-based amorphous strip is regarded as a promising material to reduce energy loss in
transformer cores and, consequently, to help mitigate global warming.
The Fe-based amorphous strip is produced by a rapidly-solidifying, direct-casting process.
The strip is intended primarily for the construction of wound cores of transformers for
commercial power frequency (50 Hz and 60 Hz) applications.
After appropriate heat treatment, the strip exhibits a significantly lower value of specific total
loss in comparison with grain-oriented electrical steel strip for the same applications. It is
associated with low hysteresis loss due to low magnetic anisotropy and with low eddy current
loss due to high resistivity and reduced thickness.

---------------------- Page: 10 ----------------------
IEC 60404-8-11:2018 © IEC 2018 – 9 –
6.2 Form of supply
The strip is supplied in coil. It shall be a single-ply coil made by a continuous single strip
wound on a spool hub, or a multi-ply coil made by a number of strips simultaneously wound
on a spool hub.
The mass of the coils shall be agreed between the manufacturer and the purchaser at the
time of enquiry and order.
The recommended value for the internal diameter of spool hubs is approximately 406 mm.
The outside diameter of coils should be at least 600 mm and should not exceed 1 120 mm.
Strip shall be of constant width and wound in such a manner that the edges are superimposed
in a regular manner and the side faces of the coil are substantially flat.
Irregular deviations from flatness and/or the size and the number of voids or openings in the
coil shall be agreed between the manufacturer and the purchaser at the time of enquiry and
order.
Coils shall be sufficiently tightly wound in order that they do not loosen under their own weight.
In the case of multi-ply coils, strips may exhibit single-ply joints if agreed between the
manufacturer and the purchaser at the time of enquiry and order. The shape of strip ends at
the joint may be agreed between the manufacturer and the purchaser at the time of enquiry
and order.
The edges of parts jointed together shall not be so much out of alignment as to affect the
further processing of the strip.
6.3 Delivery condition
Fe-based amorphous strip is usually supplied without an insulating coating. An oxide layer is
formed naturally on the strip surface during the manufacture of the strip.
6.4 Surface condition
The surfaces shall be smooth and clean, free from grease and rust. No continuous indication
of oxide shall be visible along the surfaces or edges of the strip.
The surfaces and edges shall have no wrinkles, dimples, cracks, folds, flakes or other defects
that would make the strip unsuitable for the fabrication of wound cores. Dispersed
imperfections such as minor rusts, slight coloration, small pinholes, shallow dimples, etc. are
permitted if they are not detrimental to the correct use of the supplied strip.
The strip shall have no needle-like holes exceeding 7,0 mm in length. The strip shall have no
more than eight needle-like holes aligned in the direction of casting of the strip in any 25 mm
long segment.

7 Technical requirements
7.1 Magnetic properties
7.1.1 Reference condition
The properties defined in 7.1.2 and 7.1.3 shall apply only to test specimens in the reference
condition which is obtained by the following magnetic annealing.
The test specimens shall be subjected to magnetic annealing in a DC magnetic field directed
parallel to the direction of casting, at least 1 600 A/m in strength and at a temperature in
accordance with the specification of the manufacturer.
The magnetic annealing shall be maintained for 2 h at the temperature and maintained until
the temperature falls to 200 °C.
NOTE 1 The magnetic annealing releases stress and induces magnetic anisotropy in the casting direction.
NOTE 2 As a general guideline, the temperature for the magnetic annealing is below the onset of the
crystallization temperature, which can be determined by differential scanning calorimetry (DSC) at a heating rate of
20 K/min, between 140 °C and 170 °C.
The test specimen shall be kept flat during the magnetic annealing. The atmosphere of the
magnetic annealing shall be dry and inert.
A quick magnetic annealing may be performed at a higher temperature and for a shorter time
than the above treatments by agreement between the manufacturer and the purchaser at the
time of enquiry and order.
NOTE 3 In the case of a quick magnetic annealing, the magnetic properties of the test specimen can be poorer
than in the case of the reference condition.
7.1.2 Magnetic polarization
The specified minimum values of peak magnetic polarization for a peak magnetic field
strength of 80 A/m at 50 Hz or 60 Hz shall be as given in Table 1 and Table 2.
7.1.3 Specific total loss
The specified values of maximum specific total loss at 1,3 T and 1,4 T shall be as given in
