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 60364-7-702 has been prepared by IEC technical committee 64:

Electrical installations and protection against electric shock.

This third edition cancels and replaces the second edition published in 1997 and constitutes a

technical revision.
The main changes with respect to the previous edition are as follows:
– the scope has been improved, including natural areas in natural waters;
– the description of zones has been improved;
– all figures have been updated.
---------------------- Page: 5 ----------------------

The text of this standard is based on the following documents:
FDIS Report on voting
64/1724/FDIS 64/1728/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.

This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

The reader’s attention is drawn to the fact that Annex B lists all of the “in-some-country”

clauses on differing practices of a less permanent nature relating to the subject of this

standard.

A list of all parts in the IEC 60364 series, under the general title Low-voltage electrical

installations, can be found on the IEC website.

Future standards in this series will carry the new general title as cited above. Titles of existing

standards in this series will be updated at the time of the next edition.

The committee has decided that the contents of this publication will remain unchanged until

the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data

related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

IMPORTANT – The 'colour inside' logo on the cover page of this publication indicates

that it contains colours which are considered to be useful for the correct

understanding of its contents. Users should therefore print this document using a

colour printer.

INTRODUCTION

The requirements of this part of IEC 60364 supplement, modify or replace certain of the

general requirements contained in Parts 1 to 6 of IEC 60364.

The clause numbering appearing after 702 refers to the corresponding parts or clauses of

IEC 60364, Parts 1 to 6 . Numbering of clauses does not, therefore, necessarily follow

sequentially. Numbering of additional text is shown by the addition of “.101, etc”. Numbering

of figures and tables takes the number of this part followed by a sequential number. For

annexes, the numbering of figures and tables takes the letter of the annex, the number of the

part and a sequential number.

The absence of reference to a part or clause means that the general requirements contained

in Parts 1 to 6 of IEC 60364 are applicable.
___________

For historical reasons, IEC 60364-1:2005 numbering is as follows: 11 Scope; 12 Normative references; 20

Terms and definitions, etc.

– barriers or enclosures affording at least the degree of protection according to IEC 60529

IP2X or IPXXB, or
– insulation capable of withstanding a test voltage of 500 V a.c. for 1 min.
702.415 Additional protection
702.415.2 Additional protection: supplementary protective equipotential bonding
Add the following:

All extraneous-conductive-parts in zones 0, 1 and 2 shall be connected by protective

equipotential bonding conductors to the protective conductors of the exposed-conductive-

parts of equipment situated in these zones.

NOTE 1 This connection with the protective conductor may be provided in close proximity to the location, for

example at an accessory or a distribution board or other equipment.
NOTE 2 See also 702.522.8 and 702.55.101.

Extraneous-conductive-parts are conductive parts not forming part of the electrical installation

and liable to introduce an electric potential, including the electric potential of a local earth –

for the scope of this standard, from outside zones 0, 1 and 2 into these zones.
NOTE 3 Such parts may, for example, be
– metallic pipelines for freshwater, waste water, gas, heating, climate control,
– metallic parts of building construction,
– metallic parts of the basin construction,
– metal reinforcement of non-insulating floors,
– metal reinforcement of concrete basins.

Floors made of individual concrete tiles, the reinforcement of which is fully encapsulated

within the tile and not accessible without damaging the tile, are not considered as extraneous-

conductive-parts and therefore need not be included in additional protective equipotential

bonding.

Concrete tiles without metallic reinforcement, tile coverings and topsoil (e.g. lawn) are not

considered as extraneous-conductive-parts and therefore need not be included in additional

protective equipotential bonding.

NOTE 4 The following conductive parts generally need not be included in additional protective equipotential

bonding:
– basin ladders and barriers;
– diving structure ladders;
– handrails and handholds on the rim of the basin;
– grid covers including the mounting frames of overflow pipes;
– window frames;
– door frames;
– starting blocks.

NOTE 1 IEC 60529 states that, unless there is a relevant product standard, the test conditions for IPX8 are

subject to agreement between manufacturer and user.

NOTE 2 For zone 0, where waterjets during cleaning operations are expected, both IPX5 (to ensure resistance to

the operations during the cleaning process) and IPX8 (to ensure resistance to the immersion in the water) are

necessary (see 4.3 of IEC 60529:1989). Both IPX5 and IPX8 are necessary because IPX8 does not include

protection against water jets.
702.52 Wiring systems
702.522 Selection and erection in relation to external influences
702.522.8 Other mechanical stresses
Add the following:
702.522.8.101 Erection according to the zones
