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 62677 has been prepared by committee TC 15: Solid electrical
insulating materials.
The text of this International Standard is based on the following documents:

INTRODUCTION
This part of IEC 62677 is one of a series that deals with heat shrinkable low and medium voltage
moulded shapes. It consists of three parts:
Part 1: General requirements (IEC 62677-1)
Part 2: Methods of test (IEC 62677-2) 1
Part 3: Specification for individual materials
This standard gives one of the sheets comprising Part 3 as follows:
Sheet 103: Heat shrinkable, polyolefin, conductive moulded shapes for medium voltage
applications

HEAT-SHRINKABLE LOW AND MEDIUM VOLTAGE MOULDED SHAPES
Part 3: Specification for individual materials
Sheet 103: Heat-shrinkable, polyolefin, conductive moulded shapes for
medium voltage applications
1 Scope
This part of IEC 62677 is applicable to heat shrinkable low and medium voltage moulded
shapes, conductive, in a range of configurations suitable for environmental sealing, mechanical
protection, strain relief for power cable terminations, joints and stop ends. These moulded
shapes have been found suitable for use for temperatures between −40 ºC and 100 ºC.
The moulded shapes can be supplied with a pre-coated adhesive. A guide to adhesive
compatibility and temperature performance is given in Annex A. The manufacturers/suppliers
can be consulted for options.
Materials which conform to this specification meet established levels of performance. However,
the selection of a material by a user for a specific application will need to be based on the actual
requirements necessary for adequate performance in that application and not based on this
