– guidance on voltage levels for routine tests;
– additional figures to show testing details and oscillograms of normal and faulty coils.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
(dop) 2010-02-01
national standard or by endorsement
– latest date by which the national standards conflicting
(dow) 2012-05-01

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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60034-15 has been prepared by IEC technical committee 2:
Rotating machinery.
This third edition cancels and replaces the second edition published in 1995 and constitutes a
technical revision. The principal technical changes are as follows.
• Change of title to clarify that it is form-wound coils that are being tested rather than
machines.
• Removal of the limitation on voltage in the Scope.
• Additional definitions for consistency with IEC 60060-1.
• Reduction in tolerances for the risetime of the steep-fronted impulse voltage.
• Guidance on test levels for coils to be used in converter driven machines.
• Guidance on voltage levels for routine tests.
• Additional figures to show testing details and oscillograms of normal and faulty coils.

INTRODUCTION
IEC 60071-1 specifies general requirements for the phase to earth insulation of equipment
in three phase a.c. systems and states that each apparatus committee is responsible
for specifying the insulation levels and test procedures for its equipment, taking into
consideration the recommendations of IEC 60071-1. The object of IEC 60034-15 is to specify
requirements for rotating electrical machines. Experience has shown that the values given in
this standard meet the insulation requirements for the essential stresses in service. An
explanation of the principles adopted in preparing these requirements is given in Annex A.
This standard is not intended for soft-start machines.
