IEC 62305-3 Ed. 3.0 b:2024 ✓ Most Recent

This part of IEC 62305 provides the requirements for protection of a structure against physical damage by means of a lightning protection system (LPS), and for protection against injury to human beings due to touch and step voltages in the vicinity of an LPS (see IEC 62305-1).

This document is applicable to the:
a) design, installation, inspection and maintenance of an LPS for structures without limitation of their height,
b) establishment of measures for protection against injury to human beings primarily due to touch and step voltages.

NOTE 1 Specific requirements for an LPS in structures dangerous to their surroundings due to the risk of explosion are provided in Annex C.

NOTE 2 This document is not intended to provide protection against failures of electrical and electronic systems due to overvoltages. Specific requirements for such cases are provided in IEC 62305-4.

NOTE 3 Specific requirements for the protection against lightning of wind turbines are reported in IEC 6140024 [1]1.

NOTE 4 Specific requirements for the protection against overvoltage of photovoltaic systems are reported in IEC 61643-32 [2] and in IEC 62305-4:2024, Annex F.
