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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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.

INTRODUCTION
The practice of using spark-testers to detect defects in the insulation or sheathing layers of
electric cables has been developed over many years of practical experience.
The operation of the equipment using the verification method described in this standard has
proved to be satisfactory. This method employs an artificial fault simulator and its
performance has been shown to be comparable to that using operational efficacy tests
involving the detection of artificially prepared defects (i.e. faults in the insulation/sheathing
material) in lengths of cable.

ELECTRIC CABLES –
SPARK-TEST METHOD
1 Scope
The spark-test method specified in this standard is intended for the detection of defects in the
insulation or sheathing layers of electric cables. For single core cables with no outer metallic
layer, the general process is accepted as being equivalent to subjecting samples of those
cables to a voltage test in water.
This standard specifies the operational requirements for the spark-test equipment, as well as
the principal characteristics, functional parameters and calibration procedures for each type of
test equipment.
2 Types of voltage waveform
For the purposes of this standard, the types of voltage waveform used for spark-testing are
divided into the following groups:
a.c. an alternating current (a.c.) voltage of approximately sine-wave form, at the
industrial frequency of 40 Hz to 62 Hz;
d.c. a direct current (d.c.) voltage;
h.f. an alternating current (a.c.) voltage of approximately sine-wave form, at
frequencies between 500 Hz and 1 MHz;
pulsed a voltage waveform comprising a fast rise time and highly damped wave-tail, as
defined in 4.2.
NOTE Provided the manufacturer can demonstrate equivalent effectiveness, h.f. voltages at frequencies be
