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.

INTRODUCTION
This International Standard is one of a series that deals with heat-shrinkable moulded shapes for
electrical purposes.
The series consists of three parts:
Part 1: Definitions and general requirements (IEC 62329-1)
Part 2: Methods of test (IEC 62329-2)
Part 3: Specification requirements for shape dimensions, material requirements and compatibility
performance (IEC 62329-3)
This standard gives one of the sheets comprising Part 3 as follows:
Sheet 102: Heat-shrinkable elastomeric moulded shapes, semi-rigid, material requirements and
system performance
NOTE See IEC 62329-3-100 for moulded shape dimensions.

HEAT-SHRINKABLE MOULDED SHAPES –

Part 3: Specification requirements for shape dimensions,
material requirements and compatibility performance –
Sheet 102: Heat-shrinkable elastomeric moulded shapes, semi-rigid,
material requirements and system performance



1 Scope
This sheet of IEC 62329-3 gives the requirements for heat-shrinkable elastomeric moulded shape,
semi-rigid material requirements and system performance.
Experience of product performance indicates that this moulded shape material is suitable for
inclusion in systems for operation in the following temperature ranges: –75 °C to + 120 °C.
The moulded shapes may be supplied with a pre-coated adhesive. Refer to the
manufacturers/suppliers for options. A guide to adhesive compatibility is given in Annex A.
These moulded shapes are normally supplied in the styles and dimensions given in IEC 62329-3-
100. The colour is normally Black.
Styles and dimensions other than those specifically listed in IEC 62329-3-100 may be available as
custom items. These items shall be considered to comply with this standard if they comply with the
property requirements listed in Table 1 with the exception of dimensions.
Materials that conform to this specification meet established levels of performance. However, the
selection of a material by a user for a specific application should be based on the actual
requirements necessary for adequate performance in that application and not based on this
specification alone.
2 Normative references

dated references, only the edition cited applies. For undated references, the latest edition of the
referenced document (including any amendments) applies
