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 60684-3-216 has been prepared by IEC technical committee 15:
Solid electrical insulating materials.
This second edition cancels and replaces the first edition published in 2001,
Amendment 1:2005 and Amendment 2:2013. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) the temperature at which the sleeving is shrunk in a forced-air circulation oven for
(5 ± 1) min has been increased from (150 ± 5) °C to (200 ± 5) °C.
The text of this International Standard is based on the following documents:
FDIS Report on voting
15/888/FDIS 15/902/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 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 document comprises one of the sheets of Part 3 as follows:
Sheet 216: Heat-shrinkable, flame-retarded, limited-fire-hazard sleeving

FLEXIBLE INSULATING SLEEVING –

Part 3: Specifications for individual types of sleeving –
Sheet 216: Heat-shrinkable, flame-retarded,
limited-fire-hazard sleeving
1 Scope
This sheet part of IEC 60684-3 gives the requirements for four types of heat-shrinkable,
flame-retarded, limited-fire-hazard sleeving with a thermal endurance rating of 105 °C as
shown below.
Class A: thin wall shrink ratio 2:1 internal diameter up to 102,0 mm
Class B: medium wall shrink ratio 2:1 internal diameter up to 60,0 mm
Class C: thick wall shrink ratio 2:1 internal diameter up to 51,0 mm
Class D: medium wall shrink ratio 3:1 internal diameter up to 40,0 mm
These sleevings are normally supplied in the following colours: black, red, green, blue, white,
yellow and green/yellow.
Sizes or colours other than those listed in this document may be are available as custom
items. These items shall be are considered to comply with this document if they comply with
the property requirements listed in Tables 5, 6, 7 and 8, excluding dimensions and mass.
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.
