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.
International Standard IEC 60684-3-271 has been prepared by IEC technical committee 15:
Solid electrical insulating materials.
This third edition cancels and replaces the second edition published in 2004, and constitutes a
technical revision. It includes the following significant technical change from the previous
edition: the addition of a type of sleeving suitable for use at temperatures up to 150 °C.
The text of this standard is based on the following documents:

This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
A list of all the parts in the IEC 60684 series, under the general title Flexible insulating
sleeving, can be found on the IEC website.
The committee has decided that the contents of this publication will remain unchanged until the
stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data related to
the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

INTRODUCTION
This International Standard is part 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 is one of the sheets comprising Part 3, as follows:
Sheet 271: Heat-shrinkable elastomer sleevings, flame retarded, fluid resistant, shrink ratio
2:1.

FLEXIBLE INSULATING SLEEVING –

Part 3: Specifications for individual types of sleeving –
Sheet 271: Heat-shrinkable elastomer sleevings, flame retarded,
fluid resistant, shrink ratio 2:1

1 Scope
This part of IEC 60684 gives the requirements for four types of heat-shrinkable, flame retarded,
fluid resistant, elastomer sleevings, nominal shrink ratio of 2:1.
Type A: standard wall thickness for use at temperatures up to 120 °C
Type B: thin wall thickness for use at temperatures up to 120 °C
Type C: standard wall thickness for use at temperatures up to 150 °C
Type D: thin wall thickness for use at temperatures up to 150 °C
These sleevings are normally supplied with internal diameters up to 102 mm for the standard
wall thickness and up to 51 mm for the thin wall thickness. The standard colour is black.
Sizes or colours other than those specifically 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 1, 2, 3, 4, 5 and 6 except for 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 be based on the actual
requirements necessary for adequate performance in that application and not based on this
specification alone.
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 of
the referenced document (including any amendments) applies.

3 Designation
The sleeving shall be identified by the following designation:
Description IEC publication IEC part IEC sheet Type Size (expanded/ Colour Table
number number number recovered internal
6*
diameter, in mm)
Code
↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓
Sleeving IEC 60684 -   3 -   271 -  A -  12,7/6,4 BK X

Any abbreviation for colour shall comply with IEC 60757, where applicable. Non-standard
colours shall be written out in full.
* The addition of “X” at the end of the designation indicates that the properties contained in
Table 6 have been agreed upon between the user and supplier.
4 Conditions of test
Unless otherwise specified, the sleeving shall be shrunk in a forced air circulation oven for
(5 ± 1) min at 200 °C ± 5 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, 4, 5 and 6 where applicable.
6 Sleeving conformance
Product conformance shall normally be based on the results from size 12,7/6,4 mm black
sleeving. The colour fastness to light shall be qualified for all colours.
