FLEXIBLE INSULATING SLEEVING –



Part 3: Specifications for individual types of sleeving –

Sheet 214: Heat-shrinkable, polyolefin sleeving,

not flame retarded, thick and medium wall





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 60684-3-214 has been prepared by IEC technical committee 15:
Solid electrical insulating materials.
This third edition cancels and replaces the second edition published in 2005. This edition
constitutes a technical revision.
This edition includes the following significant technical change with respect to the previous
edition:
Alignment with IEC 60684-3-247 (dual wall) since this Part 3 specification represents a single
wall option using identical material.

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 gives one of the sheets comprising Part 3 as follows:
Sheet 214: Heat-shrinkable, polyolefin sleeving, not flame retarded, thick and medium wall.

FLEXIBLE INSULATING SLEEVING –



Part 3: Specifications for individual types of sleeving –

Sheet 214: Heat-shrinkable, polyolefin sleeving,

not flame retarded, thick and medium wall








1 Scope

This standard gives the requirements for two types of heat-shrinkable, polyolefin sleeving, not
flame retarded, thick and medium wall with a nominal shrink ratio of 3:1.
This sleeving has been found suitable for use at temperatures of up to 100 °C.
Type A: Medium wall – internal diameter up to 200 mm typically.
Type B: Thick wall – internal diameter up to 200 mm typically.
These sleevings are normally supplied in colour black.
Since these types of sleevings cover a significantly large range of sizes and wall thicknesses,
Tables A.1 and A.2 of this document provides a guide to the range of sizes available. The
actual size will be agreed between the user and supplier.
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 documents, in whole or in part, are normatively referenced in this document and
are indispensable for its application. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments)
applies.
