Flexible insulating sleeving - Part 3: Specifications for individual types of sleeving - Sheet 280: Heat-shrinkable, polyolefin sleeving, anti-tracking

IEC 60684-3-280:2019 is available as IEC 60684-3-280:2019 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC 69684-3-280:2019 gives the requirements for heat-shrinkable, polyolefin sleeving, anti-tracking with a nominal shrink ratio of 3:1. This sleeving has been found suitable for use at temperatures up to 100 °C. Typically: medium wall, internal diameter up to 110 mm. This sleeving is normally supplied in the colours red or brown. Since these types of sleeving cover a significantly large range of sizes and wall thicknesses, Annex A (Table A.1) provides guidance on the range of sizes available. The actual size will be agreed between the user and the supplier. Materials which conform to this specification 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 not based on this specification alone. This sleeving is designed to be used in medium voltage cable accessories and as such electrical performance willbe proven as part of the assembly. Examples of this are described in HD 629.1 and IEC 60502 (all parts). This second edition cancels and replaces the first edition published in 2010 and Amendment 1:2013. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- change of moulded plaque thickness for resistance to tracking and weathering tests to (6 ± 0,5) mm.
Keywords: Heat-shrinkable, polyolefin sleeving, anti-tracking

IEC 60684-3-280:2019 est disponible sous forme de IEC 60684-3-280:2019 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.
IEC 60684-3-280:2019 donne les exigences relatives aux gaines thermorétractables, en polyoléfine, anticheminement, présentant un rapport de rétreint nominal de 3:1. Ces gaines se sont avérées appropriées pour une utilisation à des températures allant jusqu’à 100 °C. Généralement: paroi moyenne, diamètre intérieur jusqu’à 110 mm. Ces gaines sont normalement disponibles en rouge ou en brun. Comme ces types de gaines couvrent une plage très étendue de tailles et d’épaisseurs de paroi, l'Annexe A (Tableau A.1) donne des recommandations sur la plage des tailles disponibles. La taille réelle fait l’objet d’un accord entre l’utilisateur et le fournisseur. Les matériaux conformes à la présente spécification satisfont à des niveaux de performances établis. Cependant, le choix d’un matériau par un utilisateur, pour une application spécifique, est fondé sur les exigences réelles nécessaires pour obtenir des performances adéquates pour l'application concernée, et n'est pas fondé sur cette seule spécification.Anchor Cette gaine est conçue pour être utilisée dans des accessoires de câbles moyenne tension, et, en conséquence, les performances électriques sont prouvées dans le cadre de l’assemblage. Des exemples sont décrits dans le HD 629.1 et dans l'IEC 60502 (toutes les parties). Cette deuxième édition annule et remplace la première édition parue en 2010 et l'Amendement 1:2013. Cette édition constitue une révision technique. La présente édition inclut la modification technique majeure suivante par rapport à l'édition précédente:
- modification de l'épaisseur des plaques moulées pour les essais de résistance aux courants de cheminement et les essais de résistance aux intempéries qui devient (6 ± 0,5) mm.

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 60684-3-280 has been prepared by IEC technical committee 15:

FLEXIBLE INSULATING SLEEVING –
Part 3: Specifications for individual types of sleeving –
Sheet 280: Heat-shrinkable, polyolefin sleeving, anti-tracking
1 Scope

This part of IEC 60684 gives the requirements for heat-shrinkable, polyolefin sleeving, anti-

tracking with a nominal shrink ratio of 3:1.
This sleeving has been found suitable for use at temperatures up to 100 °C.
Typically: medium wall, internal diameter up to 110 mm.
This sleeving is normally supplied in the colours red or brown.

Since these types of sleeving cover a significantly large range of sizes and wall thicknesses,

Annex A (Table A.1) provides guidance on the range of sizes available. The actual size will be

agreed between the user and the supplier.

Materials which conform to this specification 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 not based on

this specification alone.

This sleeving is designed to be used in medium voltage cable accessories and as such

electrical performance willbe proven as part of the assembly. Examples of this are described

in HD 629.1 and IEC 60502 (all parts).

1) La Commission Electrotechnique Internationale (IEC) est une organisation mondiale de normalisation

composée de l'ensemble des comités électrotechniques nationaux (Comités nationaux de l’IEC). L’IEC a pour

objet de favoriser la coopération internationale pour toutes les questions de normalisation dans les domaines

de l'électricité et de l'électronique. A cet effet, l’IEC – entre autres activités – publie des Normes

internationales, des Spécifications techniques, des Rapports techniques, des Spécifications accessibles au

public (PAS) et des Guides (ci-après dénommés "Publication(s) de l’IEC"). Leur élaboration est confiée à des

comités d'études, aux travaux desquels tout Comité national intéressé par le sujet traité peut participer. Les

organisations internationales, gouvernementales et non gouvernementales, en liaison avec l’IEC, participent

également aux travaux. L’IEC collabore étroitement avec l'Organisation Internationale de Normalisation (ISO),

selon des conditions fixées par accord entre les deux organisations.

2) Les décisions ou accords officiels de l’IEC concernant les questions techniques représentent, dans la mesure

du possible, un accord international sur les sujets étudiés, étant donné que les Comités nationaux de l’IEC

intéressés sont représentés dans chaque comité d’études.

3) Les Publications de l’IEC se présentent sous la forme de recommandations internationales et sont agréées

comme telles par les Comités nationaux de l’IEC. Tous les efforts raisonnables sont entrepris afin que l’IEC

s'assure de l'exactitude du contenu technique de ses publications; l’IEC ne peut pas être tenue responsable de

l'éventuelle mauvaise utilisation ou interprétation qui en est faite par un quelconque utilisateur final.

4) Dans le but d'encourager l'uniformité internationale, les Comités nationaux de l’IEC s'engagent, dans toute la

mesure possible, à appliquer de façon transparente les Publications de l’IEC dans leurs publications nationales

et régionales. Toutes divergences entre toutes Publications de l’IEC et toutes publications nationales ou

régionales correspondantes doivent être indiquées en termes clairs dans ces dernières.

5) L’IEC elle-même ne fournit aucune attestation de conformité. Des organismes de certification indépendants

fournissent des services d'évaluation de conformité et, dans certains secteurs, accèdent aux marques de

conformité de l’IEC. L’IEC n'est responsable d'aucun des services effectués par les organismes de certification

indépendants.

6) Tous les utilisateurs doivent s'assurer qu'ils sont en possession de la dernière édition de cette publication.

7) Aucune responsabilité ne doit être imputée à l’IEC, à ses administrateurs, employés, auxiliaires ou

mandataires, y compris ses experts particuliers et les membres de ses comités d'études et des Comités

nationaux de l’IEC, pour tout préjudice causé en cas de dommages corporels et matériels, ou de tout autre

dommage de quelque nature que ce s
