IEC 60684-3-284:2014

Flexible insulating sleeving - Part 3: Specifications for individual types of sleeving - Sheet 284: Heat-shrinkable sleevings, for oil barrier applications

IEC 60684-3-284:2014 gives the requirements for heat-shrinkable sleevings for oil barrier, medium voltage cable jointing and termination applications, with nominal shrink ratios of up to 3:1. These sleevings have been found suitable for use up to temperatures of 80 °C. Included are Type A: polyolefin based and Type B: fluoropolymer based, enhanced oil resistance. These sleevings are normally supplied as translucent. Since these types of sleevings cover a significantly large range of sizes and wall thicknesses, Annex A, Tables A.1 and A.2, in this document, provide a guide to the range of sizes available. The actual size will be agreed between the purchaser and supplier. Materials which conform to this standard 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 standard alone. This sleeving is designed to be used in MV cable accessories and as such, electrical performance as defined as part of the assembly. Examples of this are described in HD 629 and IEC 60502 series. Keywords: heat-shrinkable sleevings, oil barrier, medium voltage cable jointing, termination applications

Gaines isolantes souples - Partie 3: Spécifications pour types particuliers de gaines - Feuille 284: Gaines thermorétractables pour applications de barrière résistant à l'huile

L'IEC 60684-3-284:2014 fournit les exigences relatives aux gaines thermorétractables pour applications de jonction et de terminaison de câble moyenne tension avec barrière résistant à l'huile, possédant des rapports de rétr-eint nominaux jusqu'à 3:1. Ces gaines se sont révélées être adaptées à une utilisation à des températures allant jusqu'à 80 °C Type A; à base de polyoléfine. Type B; à base de fluoropolymère, résistance améliorée à l'huile. Ces gaines sont normalement fournies en matériau translucide. Comme ces types de gaines couvrent une gamme très large de dimensions et d'épaisseurs de paroi, l'Annexe A, les Tableaux A.1 et A.2, du présent document fournissent des lignes directrices sur la gamme des dimensions disponibles. La dimension réelle fera l'objet d'un accord entre l'acheteur et le fournisseur. Les matériaux conformes à la présente norme satisfont à des niveaux de performance établis. Cependant, il convient que le choix d'un matériau par un utilisateur pour une application particulière soit fondé sur les exigences réelles nécessaires pour obtenir les performances satisfaisantes pour cette application, et qu'il ne soit pas fondé uniquement sur la présente norme. Ces gaines sont conçues pour être utilisées dans des accessoires de câbles moyenne tension et, en conséquence, les performances électriques sont définies dans le cadre de l'assemblage concerné. De tels exemples sont décrits dans le HD 629 et l'IE applications de jonction et de terminaison de câble moyenne tension C 60502. Mots clés: Gaines thermorétractables, barrière résistant à l'huile, de terminaison de câble moyenne tension applications

FLEXIBLE INSULATING SLEEVING –

Part 3: Specifications for individual types of sleeving –
Sheet 284: Heat-shrinkable sleevings, for oil barrier applications

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 60684-3-284 has been prepared by IEC technical committee 15:

INTRODUCTION
This International Standard is one of a series which deals with flexible insulating sleeving for
electrical purposes.
The series consists of three parts:
Part 1: Definitions and general requirements (IEC 60684-1)
Part 2: Methods of test (IEC 60684-2)
Part 3: Specifications for individual types of sleeving (IEC 60684-3)
This standard gives one of the sheets comprising Part 3, as follows:
Sheet 284: Heat-shrinkable sleevings, for oil barrier applications.

FLEXIBLE INSULATING SLEEVING –

Part 3: Specifications for individual types of sleeving –
Sheet 284: Heat-shrinkable sleevings, for oil barrier applications



1 Scope
This part of IEC 60684 gives the requirements for heat-shrinkable sleevings for oil barrier,
medium voltage cable jointing and termination applications, with nominal shrink ratios of up to
3:1.
These sleevings have been found suitable for use up to temperatures of 80 °C.
Type A: polyolefin based.
Type B: fluoropolymer based, enhanced oil resistance.
These sleevings are normally supplied as translucent.
Since these types of sleevings cover a significantly large range of sizes and wall thicknesses,
Annex A, Tables A.1 and A.2, in this document, provide a guide to the range of sizes
available. The actual size will be agreed between the purchaser and supplier.
Materials which conform to this standard 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
standard alone.
This sleeving is designed to be used in MV cable accessories and as such, electrical
performance as defined as part of the assembly. Examples of this are described in HD 629
and IEC 60502 series.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and
are indispensable for its application. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any
amendments) applies.
