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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC

IEC 60684-3-116 has been prepared by IEC technical committee 15: Solid electrical insulating
materials. It is an International Standard.
This fourth edition cancels and replaces the third edition published in 2010 and constitutes a
technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) update of clause references in Table 2;
b) addition of resistance to fluids test.
The text of this International Standard is based on the following documents:

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: Specification requirements for individual types of sleeving (IEC 60684-3).
This document comprises two of the sheets of Part 3, as follows:
Sheet 116: Extruded polychloroprene, general purpose: thin wall;
Sheet 117: Extruded polychloroprene, general purpose: thick wall.

FLEXIBLE INSULATING SLEEVING –

Part 3: Specifications for individual types of sleeving –
Sheets 116 and 117: Extruded polychloroprene, general purpose

1 Scope
This part of IEC 60684 gives the requirements for non-heat-shrinkable sleeving, extruded from
compounds based on polychloroprene elastomer. This sleeving has been found suitable for
temperatures up to 95 °C.
Sleeving of this type is normally available with internal diameters up to 25 mm, and in the
following opaque colours: black, brown, red, orange, yellow, green, blue, violet, grey, white and
pink. Sizes or colours other than those specifically listed in this document may can possibly be
available as custom items. These items shall be are considered to comply with this document
if they comply with the other property requirements listed in Table 2.
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 the application and not based on the
specification alone.
2 Normative references
