Lightning protection system components (LPSC) - Part 1: Requirements for connection components
IEC 62561-1:2023 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. This third edition cancels and replaces the second edition published in 2017. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) definitions of connection types mentioned in the scope have been added;
b) location classification has been expanded in detail;
c) the document has been updated in line with the new edition of ISO 22479:2019 on humid sulphurous atmosphere treatment;
d) a new normative Annex E for reduced test procedures has been introduced.
Composants des systèmes de protection contre la foudre (CSPF) - Parte 1: Exigences pour les composants de connexion
L'IEC 62561-1:2023 spécifie les exigences et les essais applicables aux composants métalliques de connexion qui font partie d'un système de protection contre la foudre (SPF). Il peut s'agir, en général, des connecteurs, des colliers de serrage, des composants de collage et de pontage, des pièces de dilatation et des joints de contrôle. Cette troisième édition annule et remplace la deuxième édition parue en 2017. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) les définitions des types de connexions mentionnés dans le domaine d'application du document ont été ajoutées;
b) la classification des emplacements a été développée de façon détaillée;
c) le document a été mis à jour conformément à la nouvelle édition de l'ISO 22479:2019 concernant le traitement en atmosphère humide sulfureuse;
d) la nouvelle Annexe E normative concernant les procédures d'essai simplifiées a été introduite.

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 conten
