Foreword
The text of document 15/237/FDIS, future edition 3 of IEC 60455-3-5, prepared by IEC TC 15, Standards
on specifications for electrical insulating materials, was submitted to the IEC-CENELEC parallel vote and
was approved by CENELEC as EN 60455-3-5 on 2006-02-01.
This European Standard supersedes 60455-3-5:2001.
The major changes from EN 60455-3-5:2001 concern the introduction of unsaturated polyester with low
emission of volatile organic components. A definition, requirements and a test method for curing in thick
layer and emissions during curing were added.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2006-11-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2009-02-01
Annex ZA has been added by CENELEC.

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.
This International Standard has been prepared by IEC technical committee 15: Standards on
specifications for electrical insulating materials.
This third edition of IEC 60455-3-5 cancels and replaces the second edition (2001) and
constitutes a technical revision. The major changes from the previous edition concern the
introduction of unsaturated polyester with low emission of volatile organic components.
Definition, requirements and a test method for curing in thick layer and emissions during
curing were added.

the data related to the specific publication. At this date, the publication will be
• reconfirmed;

INTRODUCTION
This part of IEC 60455 is one of a series which deals with specifications for resin based
reactive compounds and their components used for electrical insulation. The series consists
of three parts:
Part 1: Definitions and general requirements (IEC 60455-1);
Part 2: Methods of test (IEC 60455-2);
Part 3: Specifications for individual materials (IEC 60455-3).
This standard consists of one of the sheets comprising part 3 as follows:
Sheet 5: Unsaturated polyester based impregnating resins
