LIGHTNING PROTECTION SYSTEM COMPONENTS (LPSC) –

Part 2: Requirements for conductors and earth electrodes

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 62561-2 has been prepared by subcommittee 81: Lightning
protection.
This second edition cancels and replaces the first edition published in 2012. This edition
constitutes a technical revision.
This edition includes the following significant technical change with respect to the previous
edition:
a) Tables 2 and 4 have been merged into one Table (Table 2).
b) Figure 2 showing the coating measurement of a plate conductor has been added.

Conductors and earth electrodes shall be designed in such a manner that, when they are
installed in accordance with the manufacturer's instructions, their performance shall be
reliable, stable and safe to persons and surrounding equipment.
The choice of a material depends on its ability to match the particular application
requirements such as life cycle of the material, effects from galvanic corrosion and
compatibility with other interconnected materials or services.
A summary of the requirements are given in Annex C and Annex D and their corresponding
tests are given in Annex A, Annex B and the sequence of tests in Annex E (Figure E.1),
Annex F (Figure F.1) and Annex G (Figure G.1).
4.2 Documentation
The manufacturer or supplier of the conductors and earth electrodes shall provide adequate
information in their literature to ensure that the installer of the conductors and earth
electrodes can select and install the materials in a suitable and safe manner, in accordance
with IEC 62305-3 and IEC 62305-4.
Compliance is checked by inspection.
4.3 Air-termination conductors, air-termination rods, earth lead-in rods and down-
conductors
The material, configuration and cross-sectional area of the conductors and rods, shall be in
accordance with Table 1. Their mechanical and electrical characteristics shall be in
accordance with Table 2.
Other materials may be used if they possess equivalent mechanical and electrical
characteristics and corrosion resistance properties for the intended application.
Other configurations may be used if the relevant dimensions are met.
Coated conductors and rods shall be corrosion resistant and the coating shall exhibit good
adherence to the base material.
Compliance is checked by the tests of 5.2.2, 5.2.3, 5.2.4, 5.2.5 and 5.2.6.
NOTE A summary of requirements for the cross-sectional area, mechanical and electrical characteristics as well
as tests is given in Annex C.
