HEAT SHRINKABLE MOULDED SHAPES –

Part 1: Definitions and general requirements

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.
This International Standard has been prepared by IEC technical committee 15: Standards on
specifications for electrical insulating materials.
This bilingual version (2014-05) corresponds to the English version, published in 2005-11.

INTRODUCTION
This standard is one of a series which deals with heat shrinkable moulded shapes for electrical
insulation purposes. The series will consist of three parts:
Part 1: Definitions and general requirements
Part 2: Methods of test
Part 3: Specification requirements for shape dimensions, material requirements and
compatibility performance
HEAT SHRINKABLE MOULDED SHAPES –

Part 1: Definitions and general requirements

1 Scope
This standard is applicable to heat shrinkable moulded shapes in a range of configurations and
materials suitable for insulation, environmental sealing, mechanical protection and strain relief
for connector/cable terminations and multi-way transitions. It specifies the design and
dimensions, test methods, material requirements and compatibility performance. The most
commonly available shapes are as shown in Annex A.
Materials which 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
The following referenced documents are indispensable for the application of this document. For
dated references, only the edition cited applies. For undated references, the latest edition of
the referenced document (including any amendments) applies.
IEC 60050(212):1990, International Electrotechnical Vocabulary − Chapter 212: Insulating
solids, liquids and gases

3 Terms and definitions
For the purposes of this document, the terms and definitions of the International
Electrotechnical Vocabulary IEC 60050-212, Section 1 (Terms relating to electrical properties),
apply as well as the following:
3.1
central value
the middle result of an odd number of measurements or the mean of the two middle results of
an even number of measurements when arranged in order of magnitude
3.2

4 Specimens
4.1 Moulded shape material specimens
Unless otherwise specified, specimens shall be cut from standard test sheets (2 ± 0,15) mm
thick, prepared from the same heat shrinkable material as is used to manufacture the heat
shrinkable moulded shapes. The dimensions of the sheet shall be sufficient to enable any of
the relevant tests in Part 3 to be performed.
NOTE A suitable size has been found to be 150 mm x 150 mm.
4.2 Moulded shape compatibility specimens
Specimens for test of compatibility shall consist of a moulded shape, cable sheathed with heat
shrink sleeves and metal adaptor. Also, adhesives when supplied as a separate component.
The specimen configuration and sizes shall be as specified in Part 2.
5 Classification
Moulded shapes are classified by style configuration as shown in Annex A.
6 Ordering
When ordering heat shrinkable moulded shapes, purchasers shall include the description as
detailed under designation given in the Part 3 sheets.
7 Dimensions
Preferred types and sizes are given in Part 3 but may be subject to agreement between
purchaser and supplier.
8 Colour
The standard colour is black.
Non standard colours may be subject to agreement between customer and supplier.
9 Finish
The heat shrinkable moulded shapes shall be uniform in appearance, and free from internal
and external irregularities.
There shall be no defects capable of affecting the characteristics specified in Part 3.
10 Packaging
Heat shrinkable moulded shapes shall be supplied in
