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.
This redline version of the official IEC Standard allows the user to identify the changes
made to the previous edition. A vertical bar appears in the margin wherever a change
has been made. Additions are in green text, deletions are in strikethrough red text.

International Standard IEC 60684-3-283 has been prepared by IEC technical committee 15:
Solid electrical insulating materials.
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:
a) change of moulded plaque thickness for resistance to tracking and weathering tests to
(6 ± 0,5) mm.
The text of this International Standard is based on the following documents:
FDIS Report on voting
15/892/FDIS 15/901/RVD
Full information on the voting for the approval of this International Standard can be found in
the report on voting indicated in the above table.
This document has been drafted in accordance with the ISO/IEC Directives, Part 2.
A list of all parts in the IEC 60684 series, published under the general title Flexible insulating
sleeving, can be found on the IEC website.
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to
the specific document. At this date, the document will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
IMPORTANT – The 'colour inside' logo on the cover page of this publication indicates
that it contains colours which are considered to be useful for the correct
understanding of its contents. Users should therefore print this document using a
colour printer.
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:
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 document comprises one of the sheets of Part 3 as follows:
Sheet 283: Heat-shrinkable, polyolefin sleeving for bus-bar insulation.

FLEXIBLE INSULATING SLEEVING –
Part 3: Specifications for individual types of sleeving –
Sheet 283: Heat-shrinkable, polyolefin sleeving for bus-bar insulation
1 Scope
This part of IEC 60684 gives the requirements for two types of heat-shrinkable, polyolefin
sleeving for bus-bar insulation, with a nominal shrink ratio of 2,5:1.
This sleeving has been found suitable up to temperatures of 100 °C.
• Type A: Medium wall – internal diameter up to 170,0 mm typically
• Type B: Thick wall – internal diameter up to 165,0 mm typically
These sleevings are normally supplied in colour, red or brown.
Since these types of sleevings cover a significantly large range of sizes and wall thicknesses,
Annex A (Tables A.1 and A.2) provides guidance to the range of sizes available. The actual
size and wall thickness shall will be agreed between the user and supplier depending on the
electric strength of the installed tubing offered and the requirements of the user.
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 will be based
on the actual requirements necessary for adequate performance in that application and not
based on this specification alone.
