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
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60243-2 has been prepared by technical committee 112:
Evaluation and qualification of electrical insulation materials and systems
This third edition cancels and replaces the second edition published in 2001, and constitutes
an editorial revision.
This standard shall be read in conjunction with IEC 60243-1.
The text of this standard is based on the following documents:

This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
A list of all parts in the IEC 60243 series, published under the general title Electric strength of
insulating materials – Test methods, can be found on the IEC website.
The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,

ELECTRIC STRENGTH OF INSULATING MATERIALS –
TEST METHODS –
Part 2: Additional requirements for tests using direct voltage

1 Scope
This part of IEC 60243 gives requirements additional to those in IEC 60243-1 for the
determination of the electric strength of solid insulating materials under direct voltage stress.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and
are indispensable for its application. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any
amendments) applies.
IEC 60243-1:2013, Electric strength of insulating materials – Test methods – Part 1: Tests at
power frequencies
3 Terms and definitions
For the purposes of this document, the terms and definitions in IEC 60243-1:2013 apply.
4 Significance of the test
In addition to the requirements of Clause 4 of IEC 60243-1:2013, the following points shall be
considered when using direct-voltage tests.
For a non-homogeneous test specimen, with alternating voltage, the distribution of voltage
stress within the test specimen is determined by impedance (largely capacitive). With an
increasing direct voltage, the voltage distribution may still be largely capacitive but depends
partly on the rate of voltage increase. The resistive voltage distribution, after constant voltage
application, represents the steady-state condition. The choice between direct or alternating
voltage depends upon the purpose for which the breakdown test is to be used and, to some
extent, on the intended application of the material.
Upon direct voltage application, the following currents result: the capacitive current, the
electric absorption current, the leakage current and, in some cases, partial discharge
currents.
In addition, for materials with dissimilar layers or discontinuities, the voltage distribution
across the test specimen is also influenced, as a result of interfacial polarization, by charges
of opposite polarity, which may a
