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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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 60684-3-246 has been prepared by IEC technical committee 15:
Solid electrical insulating materials.
This third edition cancels and replaces the second edition published in 2001, and constitutes a
technical revision.
The major technical changes with regard to the second edition concern a better alignment with
existing national specifications.

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 246: Heat-shrinkable polyolefin sleeving, dual wall, non-flame retarded

FLEXIBLE INSULATING SLEEVING –

Part 3: Specifications for individual types of sleeving –
Sheet 246: Heat-shrinkable polyolefin sleeving,
dual wall, non-flame retarded
1 Scope
This part of IEC 60684 defines requirements for dual wall, non-flame retarded, heat shrinkable,
polyolefin sleeving. This sleeving has been found suitable for use up to 110 °C.
The sleeving consists of an outer layer made of a semi-rigid cross-linked material.
The inner layer is a substantially non-cross-linked polyolefin that flows and fuses during the
shrinkage process to provide a seal.
It is normally offered for sale with an internal diameter up to 25 mm in the following colours:
black, white, red, yellow, blue and translucent.
Sizes or colours other than those listed in this standard may be available as custom items.
These items are considered to comply with this standard if they comply with the property
requirements listed in Tables 2, 3, 4 and 5, excluding dimensions.
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.
