Lightning protection system components (LPSC) - Part 2: Requirements for conductors and earth electrodes

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.

Lightning protection system components (LPSC) - Part 2: Requirements for conductors and earth electrodes

IEC 62561-2:2018 specifies the requirements and tests for: - metallic conductors (other than "natural" conductors) that form part of the air-termination and down-conductor systems, - metallic earth electrodes that form part of the earth-termination system. 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 change with respect to the previous edition: a) Tables 2 and 4 have been merged into one Table (Table 2). b) Figure 2 showing the coating measurement of a plate conductor has been added The contents of the corrigendum of August 2019 have been included in this copy.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
