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.

tests carried out by the manufacturer on each manufactured length of cable to check that
each length meets the specified requirements
4 Code designation
The cables shall be marked, for example: IEC 62893 IEC 121.
NOTE The code designations for specific cable types are given in the particular specification, for instance in
IEC 62893-3.
5 Rated voltage
The rated voltage of a cable is the reference voltage for which the cable is designed.
The rated voltage in an alternating current system is expressed by the combination of two
values U /U, expressed in volts, where:
a) U is the r.m.s. value between any insulated conductor and “earth” (metal covering of the
cable or the surrounding medium);
b) U is the r.m.s. value between any two phase conductors of a multicore cable or of a
system of single core cables.
In an alternating current system, the rated voltage of a cable or cord shall be at least equal to
the nominal voltage of the system for which it is intended. This condition applies to the values
of both U and U.
The maximum permanent operating voltage of the system (AC or DC) is stated in Table 1.

Part 1: General requirements
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.

INCLUDING 0,6/1 kV –
Part 1: General requirements
1 Scope
This part of IEC 62893 specifies construction, dimensions and test requirements for cables
with extruded insulation and sheath having a voltage rating of up to and including 0,6/1 kV AC
or up to and including 1 500 V DC for flexible applications under harsh conditions for the
power supply between the electricity supply point of the charging station and the electric
vehicle (EV).
The EV charging cable is intended to supply power and, if needed, communication (for details
see the IEC 62196 series and IEC 61851-1) to an EV or plug-in hybrid vehicle (PHEV). The
charging cables are applicable for charging modes 1 to 4 of IEC 61851-1. Ordinary duty
cables with rated voltage 300/500 V are only permitted for charging mode 1 of IEC 61851-1.
Maximum conductor temperature for the cables in this part of IEC 62893 is 90 ºC.
The particular types of cables are specified in IEC 62893-3 (modes 1 to 3 for AC charging)
and in the future IEC 62893-4 (mode 4 for DC charging).
These parts are collectively referred to hereafter as “the particular specifications”.
The test methods specified are given in IEC 62893-2, IEC 60245-2, IEC 60332-1-2,
IEC 62821-1:2015, Annex B, and in the relevant parts of IEC 60811, as listed in the normative
references.
