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 62561-4 has been prepared by IEC technical committee 81:
Lightning protection.
The text of this standard is based on the following documents:
FDIS Report on voting
81/369/FDIS 81/379/RVD

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

INTRODUCTION
This Part 4 of IEC 62561 deals with the requirements and tests for conductor fasteners as
being a lightning protection system component (LPSC) designed and implemented according
to the IEC 62305 series of standards.

LIGHTNING PROTECTION SYSTEM COMPONENTS (LPSC) –

Part 4: Requirements for conductor fasteners

1 Scope
This Part 4 of IEC 62561 deals with the requirements and tests for metallic and non-metallic
conductor fasteners that are used in conjunction with the air termination, down conductor and
earth termination system.
This standard does not cover the fixing of conductor fasteners to the fabric/membrane/gravel
roofing of structures due to the vast number and types used in modern day construction.
LPSC may also be suitable for use in hazardous atmospheres. Regard should then be taken
of the extra requirements necessary for the components to be installed in such conditions.

3.1
conductor fastener
metallic, non-metallic or composite component designed to retain and support the air
termination, down conductor and earth termination system, installed at intervals along the
length of the conductors
4 Classification
Conductor fasteners are classified as follows:
a) According to material
– metallic (e.g. hot dip galvanized steel, copper, aluminium, stainless steel);
– non-metallic (e.g. PVC, plastics);
– composite (combination of metal and plastic);
b) According to fixing arrangement of the conductor within the conductor fastener
– with screws;
– without screws (e.g. clips, springs);
c) According to conductor clamping arrangement
– conductor fasteners that are designed to clamp the conductor;
– conductor fasteners that are designed to clamp but allow axial movement of the conductor.
5 Requirements
5.1 General
The conductor fastener shall carry out its function of clamping the conductor in an acceptable
and safe manner when subjected to mechanical influences, lightning discharge stress and
environmental influences.
Conductor fasteners shall comply with the tests given in Clause 6. The material of the
conductor fastener shall be compatible with the conductor it is fastening and the surface
material onto which it is mounted.
NOTE 1 Certain extreme environmental conditions make the choice of non-metallic conductor fasteners
unsuitable. Specific recommendations should be provided by manufacturers as to their suitability in varying
environments.
NOTE 2 Conductor fasteners should be so designed and constructed that safe handling is ensured, that retention
and support for the conductor is provided, and that in normal use their performance is reliable and without danger
to persons and the surrounding.
5.2 Environmental requirements
5.2.1 Corrosion resistance
Metallic or composite conductor fasteners shall withstand corrosion effects.
Compliance is checked following the manufacturer’s declaration for the classification of the
conductor fastener in accordance with Clause 4 and by test specified in 6.3.2 and 6.3.4.
5.2.2 UV resistance
Non-metallic and composite conductor fasteners shall withstand UV effects.
Compliance is checked following the manufacturer’s declaration for the classification of the
conductor fastener in accordance with Clause 4 and by test specified in 6.3.3 and 6.3.4.

5.3 Mechanical strength
5.3.1 Perpendicular and axial loads
The design of the conductor fastener shall be such that it carries the perpendicular loads
caused by the weight of the conductor, snow, ice and wind and axial loads caused by the
thermal expansion–contraction of the conductor and its weight.
Compliance is checked following the manufacturer’s declaration for the classification of the
conductor fastener in accordance with Clause 4 and by test specified in 6.4.1 and 6.4.2.
5.3.2 Impact tests
Conductor fasteners shall be so designed and constructed to withstand impact stresses
caused accidentally.
Compliance is checked by test specified in 6.4.3.
5.4 Installation instructions
The manufacturer or supplier of the conductor fastener shall provide adequate information in
his literature to ensure that the installer can select and install the component in a suitable and
safe manner, in accordance with IEC 62305-3.
Compliance is checked by in
