IEC 62561-1:2017

Lightning protection system components (LPSC) - Part 1: Requirements for connection components

IEC 62561-1:2017 specifies the requirements and tests for metallic connection components that form part of a lightning protection system (LPS). Typically, these can be connectors, clamps, bonding and bridging components, expansion pieces and test joints.
For the purposes of this document the following connection types are considered as connection components: exothermic, brazing, welding, clamping, crimping, seaming, screwing or bolting. Testing of components for an explosive atmosphere is not covered by this document.
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.

Composants des systèmes de protection contre la foudre (CSPF) - Parte 1: Exigences pour les composants de connexion

L' IEC 62561-1:2017 spécifie les exigences et les essais à appliquer aux composants métalliques de connexion faisant partie d'un système de protection contre la foudre (SPF). Il peut s'agir, typiquement, des connecteurs, des colliers de serrage, des composants de pontage, des pièces d'expansion et des joints de contrôle.
Pour les besoins du présent document, les types de connexions suivants sont considérés comme des composants de connexion: la soudure exothermique et autres procédés de soudage, le brasage, le serrage, le sertissage, l'agrafage, le vissage et le boulonnage. Les essais de composants pour atmosphère explosive ne sont pas concernés par le présent document.
Cette deuxième édition annule et remplace la première édition publiée en 2012. Cette édition constitue une révision technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a. la classification des composants de connexion permanente et non permanente;
b. les exigences et essais correspondants concernant les composants de connexion permanente, par exemple la soudure exothermique et d'autres procédés de soudage, le brasage, le sertissage ou l'agrafage;
c. un organigramme des essais destinés aux composants de connexion.

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
