MT 8 - TC 81/MT 8

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.

Applicable to the design and installation of Lightning Protection Systems (SPS) for common structures up to 60 m high, in accordance with IEC 61024-1. Provides guidelines on how to use IEC 61024-1 and assists the user with the physical design and construction, maintenance and inspection of an LPS

Contains information on the classification of structures according to the consequential effects of a lightning stroke. Gives procedures for the selection of a lightning protection system. Is to be used with part 1.

This standard is applicable to the design and installation of Lightning Protection Systems (LPS) for common structures up to 60 m high.
