LIGHTNING PROTECTION SYSTEM COMPONENTS (LPSC) –

Part 1: Requirements for connection components

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 62561-1 has been prepared by IEC technical committee 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 changes with respect to the previous
edition:
a) classification of connection components in permanent and non-permanent connection;
b) requirements and corresponding tests for permanent connection components such as
exothermic, brazing, welding, crimping, seaming;
c) flow chart of tests for connection components.

6 Tests
6.1 General condition on tests
The tests in accordance with this document are type tests (see 3.11).
• Unless otherwise specified, tests are carried out with the specimens assembled and
installed as in normal use according to the manufacturer's or supplier's installation
instructions with the recommended conductor materials, sizes and tightening torques. If
the connection component is suitable for various conductors’ materials, then it shall be
tested on each material combination.
• All tests are carried out on new specimens.
• Unless otherwise specified, three specimens are subjected to the tests and the
requirements are satisfied if all the tests are met.
• If only one of the specimens does not satisfy a test due to an assembly or a manufacturing
fault, that test and any preceding one which may have influenced the results of the test
shall be repeated and also the tests which follow shall be carried out in the required
sequence on another full set of specimens, all of which shall comply with the
requirements.
• The electrical test shall be carried out in the order given, after conditioning/ageing of the
arrangement of the specimen in accordance with 6.3.
The applicant, when submitting the sets of specimens, may also submit an additional set of
specimens which may be necessary, should one specimen fail. The testing station will then,
without further request, test the additional set of specimens and will reject it only if a fur
