Lightning protection system components (LPSC) - Part 2: Requirements for conductors and earth electrodes (IEC 62561-2:2025)
IEC 62561-2:2025 specifies the requirements and tests for
- metallic conductors (other than "natural" conductors) that form part of the air-termination and down-conductor systems, and
- metallic earth electrodes that form part of the earth-termination system.
This third edition cancels and replaces the second edition published in 2018. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) definitions of new conductor types mentioned in this document have been added;
b) the document has been updated in line with IEC 60068-2-52:2017 on salt mist treatment;
c) the document has been updated in line with ISO 22479:2019 on humid sulphurous atmosphere treatment;
d) a new normative Annex H for material, configuration and cross-sectional area test has been introduced;
e) a new normative Annex I for applicability of previous tests has been introduced.
f) equipotential earth grid has been introduced.

Composants des systèmes de protection contre la foudre (CSPF) - Partie 2: Exigences pour les conducteurs et les électrodes de terre (IEC 62561-2:2025)
L'IEC 62561-2:2025 spécifie les exigences et les essais pour:
- les conducteurs métalliques (autres que les conducteurs "naturels") qui font partie des dispositifs de capture et des réseaux de conducteurs de descente; et
- les prises de terre métalliques qui font partie du réseau de prises de terre.
Cette troisième édition annule et remplace la deuxième édition parue en 2018. Cette édition constitue une révision technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) les définitions des nouveaux types de conducteurs qui sont mentionnés dans le présent document ont été ajoutées;
b) le document a été actualisé en harmonisation avec l'IEC 60068-2-52:2017, concernant l'exposition au brouillard salin;
c) le document a été actualisé en harmonisation avec l'ISO 22479:2019, concernant l'exposition au dioxyde de soufre en atmosphère humide;
d) une nouvelle Annexe H normative concernant l'essai relatif au matériau, à la configuration et à la section a été ajoutée;
e) une nouvelle Annexe I normative concernant l'applicabilité des essais précédents a été ajoutée;
f) le concept de maillage équipotentiel du réseau de terre a été ajouté.
