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.

This consolidated version of IEC 60893-3-2 consists of the third edition (2003)
[documents 15C/1522/FDIS and 15C/1536/RVD] and its amendment 1 (2011) [documents
15/505/CDV+15/540/CDV and 15/632/RVC+15/592A/RVC]. It bears the edition number 2.1.
The technical content is therefore identical to the base edition and its amendment and
has been prepared for user convenience. A vertical line in the margin shows where the
base publication has been modified by amendment 1. Additions and deletions are
displayed in red, with deletions being struck through.

– 4 – 60893-3-2 © IEC:2003+A1:2011
International Standard IEC has been prepared by subcommittee 15C: Specifications, of IEC
technical committee 15: Insulating materials.
The amendment introduces new/improved limits of CHARPY impact strength and IZOD impact
strength for all types of rigid laminated sheets based on epoxy resins and new/improved limits
of breakdown voltage to all EP GC types and a new/improved limit of flexural strength for the
EP PC 301 and a new limit of proof tracking index for the EP GC 306 type. This amendment
also introduces new types of rigid laminated sheets based on epoxy resins.
In this revision of the IEC 60893 series of specifications, new material types have been
included, changes have been made to the property requirements of some existing types, a new
method for testing permittivity and dissipation factor has been added, and all non-specification
data for each type has been moved to a new Part 4 document − IEC 60893-4 − Typical values.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
The committee has decided that the contents of the base publication and its amendments 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.
IMPORTANT – The “colour inside” logo on the cover page of this publication indicates
that it contains colours which are considered to be useful for the correct understanding
of its contents. Users should therefore print this publication using a colour printer.

INTRODUCTION
This part of IEC 60893 is one of a series which deals with industrial rigid laminated sheets
based on thermosetting resins for electrical purposes.
This series consists of four parts:
Part 1: Definitions, designations and general requirements (IEC 60893-1)
Part 2: Methods of test (IEC 60893-2)
Part 3: Specifications for individual materials (IEC 60893-3)
Part 4: Typical values (IEC 60893-4)
IEC 60893-3-2 contains one of the specification sheets comprising Part 3, as follows:
