Abstract

IEC 62305-1:2024 provides general principles for the protection of structures against lightning, including their installations and contents, as well as persons. The following cases are outside the scope of this document: - railway systems; - vehicles, ships, aircraft, offshore installations; - underground high-pressure pipelines; - pipe, power and telecommunication lines separated from the structure; - nuclear power plants. This third edition cancels and replaces the second edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) reference to the IEC 62561 series is made in Annex D to provide a link to relevant lightning protection system components according to the IEC 62561 series; b) risk management introduces the concept of types of loss with public relevance; c) the concept of frequency of damage that can impair the availability of the internal systems within the structure has been introduced; d) surge currents due to lightning flashes have been more accurately specified for SPD dimensioning in low-voltage power systems and in telecommunication systems.
