IEC 62305-1:2023 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 placed outside 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.
