GUIDANCE ON THE LIMITS OF SURFACE IRREGULARITIES
OF FERRITE CORES –
Part 2: RM-cores
FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical reports or guides and they are accepted by the National Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60424-2 has been prepared by technical committee 51: Magnetic
components and ferrite materials.
The text of this standard is based on the following documents:
FDIS Report on voting
51/480/FDIS 51/489/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
IEC 60424 will consist of the following parts, under the general Guidance on the limits of
surface irregularities of ferrite cores:
Part 1: Generic specification (will replace IEC 60424 (1973)).
Part 2: RM-cores.
Part 3: ETD-cores and E-cores.

GUIDANCE ON THE LIMITS OF SURFACE IRREGULARITIES
OF FERRITE CORES –
Part 2: RM-cores
1 Scope
This part of IEC 60424 gives a guidance on allowable limits of surface irregularities applicable
to RM-cores in accordance with the relevant generic specification.
This standard should be considered as a sectional specification useful in the dialogue between
ferrite core manufacturers and customers about surface irregularities.
