Part 2-13: Particular requirements for auto-transformers
for general use
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 specifications, 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 61558-2-13 has been prepared by IEC technical committee 96:
Small power transformers, reactors and power supply units: Safety requirements.
Future standards in this series will carry the new general title as cited above. Titles of existing
standards in this series will be updated at the time of the next revision.
It has the status of a group safety publication in accordance with IEC Guide 104: The
preparation of safety publications and the use of basic safety publications and group safety
publications (1997).
The text of this standard is based on the following documents:
FDIS Report on voting
96/131/FDIS 96/137/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.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 3.

The committee has decided that this publication remains valid until 2005-06.
At this date, in accordance with the committee’s decision, the publication will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.
This part 2-13 is intended to be used in conjunction with IEC 61558-1. It was established on the
basis of the first edition (1997) of that standard.
This part 2-13 supplements or modifies the corresponding clauses in IEC 61558-1, so as to
convert that publication into the IEC standard: Particular requirements for auto-transformers.
This standard replaces Chapter III of IEC 60989.
When a particular subclause of part 1 is not mentioned in this part 2-13, that subclause applies
as far as is reasonable. Where this standard states "addition", "modification" or "replacement",
the relevant text of part 1 is to be adapted accordingly.
In this standard, the following print types are used:
– requirements proper: in roman type;
– test specifications: in italic type;
– explanatory matter: in smaller roman type.
In the text of the standard the words in bold are defined in clause 3.
Subclauses which are additional to those in part 1 are numbered starting from 101;
supplementary annexes are entitled AA, BB, etc.
