SUITABILITY OF TYPICAL ELECTRICAL
INSULATING MATERIAL (EIM)
FOR POLYMER RECYCLING
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.
The main task of IEC technical committees is to prepare International Standards. However, a
technical committee may propose the publication of a technical report when it has collected
data of a different kind from that which is normally published as an International Standard, for
example "state of the art".
IEC 62392, which is a technical report, has been prepared by IEC technical committee 112:
Evaluation and qualification of electrical insulating materials and systems.
The text of this technical report is based on the following documents:
Enquiry draft Report on voting

___________
Technical committee 112 was created by combining the activities of sub-committee 15E and techical committee
98. This project was initially developed in technical committee 15 and then transferred to technical committee
112.

Full information on the voting for the approval of this technical report can be found in the
report on voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
The committee has decided that the contents of this publication will remain unchanged until
the maintenance result 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.
A bilingual version of this publication may be issued at a later date.

SUITABILITY OF TYPICAL ELECTRICAL
INSULATING MATERIAL (EIM)
FOR POLYMER RECYCLING
1 Scope
This Technical Report gives information for the assessment of factors associated with the
polymer recycling and/or reuse of typical insulating materials in electrotechnical equipment. It
gives information and assistance to developers and design engineers for assessment in
selecting polymers and polymer combinations, and is a contribution to the preservation of
resources and the minimization of disposal costs at the end of a product life. The
environmental compatibility of polymers must be assessed in the light of the function of the
materials in the product and the total service life. An important aspect is the recovery of the
material at the end of the product life. The value level of material recycling as recovery option
can be improved by incorporation of suitability for dismantling into the design of the article
and the choice of insulating materials which are generally used. This document will cover
material recycling only as part of recovery.
