Heat shrinkable low and medium voltage moulded shapes - Part 2 Methods of test (IEC 62677-2:2017)

This part of IEC 62677 gives methods of test for heat shrinkable low and medium voltage
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.
The tests specified are designed to control the quality of the moulded shapes but it is
recognized that they 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.

Wärmeschrumpfende Nieder- und Mittelspannungsformteile – Teil 2: Prüfverfahren

Profilés thermorétractables basse et moyenne tensions - Partie 2: Méthodes d’essai

IEC 62677-2:2017 décrit des méthodes d'essai des 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 et aux dispositifs compensateurs de traction pour les connecteurs/extrémités de câbles et aux transitions à conducteurs multiples. Les essais spécifiés sont conçus pour contrôler la qualité des profilés, mais il est reconnu qu'ils 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. Mots clés: profilés thermorétractables basse et moyenne tensions

Toplotno skrčljive nizko- in srednjenapetostne ulite forme - 2. del: Metode preskušanja (IEC 62677-2:2017)

Ta del IEC 62677 opisuje metode preskusov za toplotno skrčljive nizko- in srednjenapetostne oblikovance v različnih konfiguracijah in iz različnih materialov, primernih za izolacijo, zaščito pred okoljskimi vplivi, mehansko zaščito in razbremenitev za ozemljitve priključkov/kablov in večsmernih prenosov.
Opisani preskusi so namenjeni nadzoru nad kakovostjo oblikovancev, pri čemer se upošteva, da so zasnovani za uporabo z nizko- in srednjenapetostnimi kabli, zato se kot del sestava preverja tudi električna zmogljivost. Primeri tega so opisani v standardih EN 50393, HD 629.1 in 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 62677-2 has been prepared by committee TC15: Solid electrical

insulating materials.
The text of this standard is based on the following documents:
