FLEXIBLE INSULATING SLEEVING −
Part 2: Methods of test
FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical reports or guides and they are accepted by the National Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60684-2 has been prepared by subcommittee 15C: Specifications,
of IEC technical committee 15: Insulating materials.
This second edition cancels and replaces the first edition published in 1984 and amendment 1
(1992). This edition constitutes a technical revision.
The text of this standard is based on the following documents:
FDIS Report on voting
15C/657/FDIS 15C/790/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
Annex A is for information only.
The contents of the corrigendum of December 1997 have been included in this copy.

INTRODUCTION
This International Standard is one of a series which deals with flexible insulating sleeving. 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)

FLEXIBLE INSULATING SLEEVING −
Part 2: Methods of test
1 General
1.1 Scope
This part of IEC 60684 gives methods of test for flexible insulating sleeving, including heat-
shrinkable sleeving, intended primarily for insulating electrical conductors and connections of
electrical apparatus, although they may be used for other purposes.
The tests specified are designed to control the quality of the sleeving but it is recognized that
they do not completely establish the suitability of sleeving for impregnation or encapsulation
processes or for other specialized applications. Where necessary, the test methods in this part
will need to be supplemented by appropriate impregnation or compatibility tests to suit the
individual circumstances.
1.2 Normative references
The following normative documents contain provisions which, through reference in this text,
constitute provisions of this part of IEC 60684. At the time of publication, the editions indicated
were valid. All normative documents are subject to revision, and parties to agreements based
on this part of IEC 60684 are encouraged to investigate the possibility of applying the most
recent editions of the normative documents indicated below. Members of IEC and ISO maintain
registers of currently valid International Standards.
