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.

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 comprises one of the sheets of Part 3 as follows:
Sheet 280: Heat-shrinkable, polyolefin sleeving, anti-tracking

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.
These sleevings are normally supplied in the colours red or brown.
Since these types of sleevings cover a significantly large range of sizes and wall thicknesses,
Table A.1 in this standard provides guidance on the range of sizes available. The actual size
shall 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 should 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 must be proven as part of the assembly. Examples of this are
described in HD 629 and IEC 60502 series.
2 Normative references
The following referenced documents are indispensable for the application of this document.
For dated references, only the edition cited applies. For undated references, the latest edition

NOTE This information is for labelling only, in accordance with IEC 60684-1.
4 Conditions of test
Unless otherwise specified, the sleeving shall be shrunk in a forced air circulation oven for
(10 ± 1) min at 200 °C ± 3 K prior to testing.
5 Requirements
In addition to the general requirements given in IEC 60684-1, the sleeving shall comply with
the requirements of Tables 1, 2, 3, and 4 where applicable.
