Flexible insulating sleeving - Part 3: Specifications for individual types of sleeving - Sheet 282: Heat-shrinkable, polyolefin sleeving - Stress control
IEC 60684-3-282:2025 gives the requirements for two types of heat-shrinkable, polyolefin sleeving, stress control, not flame retarded, with a nominal shrink ratio up to 3:1.
This sleeving has been found suitable for use up to temperatures of 100 °C.
Type A: Medium wall Internal diameter up to 65,0 mm typically
Type B: Thick wall Internal diameter up to 95,0 mm typically
Since these types of sleevings cover a significantly large range of sizes and wall thicknesses, Annex A provides guidance to the range of sizes available. The actual size will be agreed between the user and the supplier.
Gaines isolantes souples - Partie 3: Spécifications pour types particuliers de gaines - Feuille 282: Gaines thermorétractables en polyoléfine - Contrôle de contrainte
L'IEC 60684-3-282:2025 donne les exigences relatives à deux types de gaines thermorétractables, en polyoléfine, à contrôle de contrainte, non ignifugées, avec un rapport de rétreint nominal jusqu'à 3:1.
Ces gaines se sont révélées être adaptées à une utilisation à des températures allant jusqu’à 100 °C.
Type A: Paroi moyenne Diamètre intérieur type jusqu’à 65,0 mm
Type B: Paroi épaisse Diamètre intérieur type jusqu’à 95,0 mm
Comme ces types de gaines couvrent une gamme très étendue de dimensions et d’épaisseurs de paroi, l'Annexe A fournit des recommandations quant à la gamme des dimensions disponibles. Les dimensions réelles font l’objet d’un accord entre l’utilisateur et le fournisseur.

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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
shall not be held responsible for identifying any or all such patent rights.
IEC 60684-3-282 has been prepared by IEC technical committee 15: Solid electrical insulating
materials. It is an International Standard.
This second edition cancels and replaces the first edition published in 2010. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) Clause for secant modulus corrected.

can be found on the IEC website.
The committee has decided that the contents of this document will remain unchanged until the

INTRODUCTION
This document is one of a series of standards which deals with flexible insulating sleeving for
electrical purposes.
The series consists of three parts:
IEC 60684-1: Definitions and general requirements
IEC 60684-2: Methods of test
IEC 60684-3: Specifications for individual types of sleeving
This document comprises one of the sheets of IEC 60684-3 as follows:
Sheet 282: Heat-shrinkable, polyolefin sleeving – Stress control
This sleeving is normally supplied in the colour black.
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 MV cable accessories and as such electrical
performance will be proven as part of the assembly. Examples of this are described in HD 629
and IEC 60502 (all parts).

FLEXIBLE INSULATING SLEEVING –
Part 3: Specifications for individual types of sleeving –
Sheet 282: Heat-shrinkable, polyolefin sleeving – Stress control
1 Scope
This part of IEC 60684 gives the requirements for two types of heat-shrinkable, polyolefin
sleeving, stress control, not flame retarded, with a nominal shrink ratio up to 3:1.
This sleeving has been found suitable for use up to temperatures of 100 °C.
– Type A: Medium wall Internal diameter up to 65,0 mm typically
– Type B: Thick wall Internal diameter up to 95,0 mm typically
Since these types of sleevings cover a significantly large range of sizes and wall thicknesses,
Annex A provides guidance to the range of sizes available. The actual size will be agreed
between the user and the supplier.
