IEC 62677-1:2017

Heat shrinkable low and medium voltage moulded shapes - Part 1: General requirements

IEC 62677-1:2017 is applicable to heat shrinkable low and medium voltage moulded shapes in a range of configurations and materials suitable for insulation, environmental sealing, mechanical protection, electrical conductance, anti-tracking and strain relief for power cable terminations, joints and stop ends. It specifies the test methods and material requirements. The most commonly available shapes are as shown in the Annex A. Materials which conform to this document meet established levels of performance. However, the selection of a material by a user for a specific application will be based on the actual requirements necessary for adequate performance in that application and will not be based on this document alone. These moulded shapes are designed to be used in low and medium voltage cable accessories and as such electrical performance will be proven as part of the assembly. Examples of this are described in EN 50393, HD 629.1 and IEC 60502-4.

Profilés thermorétractables basse et moyenne tensions - Partie 1: Exigences générales

IEC 62677-1:2017 est applicable aux profilés thermorétractables basse et moyenne tensions dans une gamme de configurations et de matériaux adaptés à l’isolement, aux éléments d’étanchéité contre les intempéries, à la protection mécanique, à la conductance électrique, aux dispositifs anticheminement et dispositifs compensateurs de traction pour extrémités de câbles de puissance, aux joints et aux extrémités d'arrêt. Elle stipule les méthodes d'essai et les exigences de matériaux. Les profilés d'emploi courant sont présentés à l'Annexe A. Les matériaux conformes à ce document satisfont à des niveaux établis de performance. Cependant, le choix d’un matériau par un utilisateur, pour une application spécifique, sera fondé sur les exigences réelles nécessaires pour obtenir une performance adéquate pour l'application concernée, et ne sera pas fondé sur ce seul document. Ces profilés thermorétractables sont conçus pour être utilisés dans des accessoires de câbles basse et moyenne tensions et, à ce titre, la performance électrique sera prouvée dans le cadre de l'assemblage. Des exemples sont développés dans l'EN 50393, le HD 629.1 et l'IEC 60502-4.

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 62677-1 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
15/806/FDIS 15/810/RVD

HEAT SHRINKABLE LOW AND MEDIUM
VOLTAGE MOULDED SHAPES –
Part 1: General requirements
1 Scope

This document is applicable to heat shrinkable low and medium voltage moulded shapes in a

range of configurations and materials suitable for insulation, environmental sealing, mechanical

protection, electrical conductance, anti-tracking and strain relief for power cable terminations,

joints and stop ends. It specifies the test methods and material requirements. The most

commonly available shapes are as shown in the Annex A.

Materials which conform to this document meet established levels of performance. However,

the selection of a material by a user for a specific application will be based on the actual

requirements necessary for adequate performance in that application and will not be based on

this document alone.

These moulded shapes are designed to be used in low and medium voltage cable accessories

and as such electrical performance will be proven as part of the assembly. Examples of this

are described in EN 50393, HD 629.1 and IEC 60502-4.

12 Qualification approval requirements

12.1 When agreed between purchaser and supplier, the supplier shall provide third party

certification by an approval body.

12.2 Where agreed between the purchaser and supplier, the supplier shall provide details of

material composition, agreed techniques and evidence to the satisfaction of the approval body

that the heat shrinkable moulded shapes supplied conform to all the requirements listed in the

sheets of IEC 62677-3 (all parts).

No changes shall be made to the declared composition and agreed techniques used in the

production of the heat shrinkable moulded shapes without the prior written agreement of the

approval body.

Following such changes, the approval body may require a repetition of the qualification testing.

12.3 Qualification tests shall be performed on the size given in the sheets of
IEC 62677-3 (all parts).

12.4 In the event of a failure of the material or moulded shapes to conform to the

requirements of a test, the consignment shall be resampled and the test repeated using two

further sets of test specimens, Both sets shall conform to the appropriate test requirements,

otherwise the heat shrinkable moulded shapes shall be deemed not to conform to
the sheet of IEC 62677-3 (all parts).

12.5 In the absence of third party approval, the supplier may be required to supply a test

report demonstrating conformance to the relevant sheets of IEC 62677-3 (all parts).
