DIELECTRIC AND RESISTIVE PROPERTIES
OF SOLID INSULATING MATERIALS –
Part 1: General
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 62631-1 has been prepared by IEC technical committee 112:
Evaluation and qualification of electrical insulating materials and systems.
This International Standard, together with its future parts, is intended to replace certain
standards as set out and explained in the Introduction.
Such standards will, however, remain valid until the respective part of IEC 62631 is published.
The text of this standard is based on the following documents:
FDIS Report on voting
112/169/FDIS 112/176/RVD

voting indicated in the above table.

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,
• replaced by a revised edition, or
• amended.

INTRODUCTION
The IEC 62631 series is divided into four main parts, which are further subdivided into
component parts. The present Part 1 of IEC 62631 considers, general aspects related to the
measurement of dielectric and resistive properties of solid electric insulating materials. Parts
2 and 3 outline basic procedures for the measurement of dielectric and resistive properties by
means of AC and DC methods. These parts will gradually replace hitherto existing
International Standards. Part 4 will cover special methods of measurement and computational
methods.
Table 1 shows the planned future structure of IEC 62631, together with the standards it will
replace.

IEC 62631-4-2 – Thermal analysis by means of observation of dielectric properties New
Measured values of dielectric and resistive properties of solid insulating materials are
dependent upon different factors such as the magnitude and time of voltage application,
frequency, the nature and geometry of the electrodes, the surface condition, contamination,
temperature and humidity of the ambient atmosphere and of the specimens during
conditioning and measurement and, in certain cases, on electric field strength also.
Therefore, the electrical and dielectric properties covered by the IEC 62631 series may only
be comparable as far as the circumstances of the measurement’s parameters are stipulated.
The test specimen’s shape and dimensions, as well as the measurement parameters, may be
defined in product standards or the relevant parts of this series of standards dealing with test
procedures, depending on the requirements to be considered for a certain demand of
measurement. Care should be taken when using measured values from the IEC 62631 series
for the purposes of designing an electric product.
NOTE It is not possible to give a comprehensive overview covering the dielectric and resistive properties of solid
electrical insulating materials within a framework of an International Standard. Therefore, the user is encouraged to
read up on the literature such as that recommended in the bibliography.
