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 62329-3-102 has been prepared by IEC technical committee 15: Solid

electrical insulating materials.
The text of this standard is based on the following documents:
FDIS Report on voting

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.

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
