Will supersede EN 62305-2:2006

This part of IEC 62305 provides the general principles to be followed in the protection against lightning of structures including their installations and contents as well as persons. The following cases are outside the scope of this standard: railway systems; vehicles, ships, aircraft, offshore installations; underground high pressure pipelines; pipe, power and telecommunication lines not connected to a structure.

IEC 62305-3 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 living beings due to touch and step voltages in the vicinity of an LPS (see IEC 62305-1). This standard is applicable to design, installation, inspection and maintenance of an LPS for structures without limitation of their height and to establishment of measures for protection against injury to living beings due to touch and step voltages.

This international standard provides information for the design, installation, inspection, maintenance and testing of electrical and electronic system protection (ESP), and measures to reduce the risk of permanent failures due to lightning electromagnetic impulse (LEMP) within a structure. He does not cover protection against electromagnetic interference due to lightning, which may cause malfunctioning of electronic systems. However, the information reported in Annex A can also be used to evaluate such disturbances. This draft international standard does not deal with detailed design of the electrical and electronic systems themselves.

This document contains the terms and definitions of general concepts to establish a vocabulary
applicable to buildings and civil engineering works.
It comprises:
a) fundamental concepts, which can be the starting point for other, more specific, definitions;
b) more specific concepts, used in several areas of construction and frequently used in standards,
regulations and contracts.

This European Standard specifies the requirements and tests for isolating spark gaps (ISG) for lightning protection systems. ISG's can be used to indirectly bond a lightning protection system to other nearby metalwork where a direct bond is not permissible for functional reasons. Typical applications include the connection to - earth termination systems of power installations, - earth termination systems of telecommunication systems, - auxiliary earth electrodes of voltage operated earth fault circuit breakers, - rail earth electrode of AC and DC railways, - measuring earth electrodes for laboratories, - installations with cathodic protection and stray current systems, - service entry masts for low- voltage overhead cables, - bypassing insulated flanges and insulated couplings of pipelines.

This European standard specifies requirements and tests for: - metallic and non-metallic conductor fasteners that are used in conjunction with the air termination system and down conductors; - fixing of fasteners to the fabric / membrane / gravel ro ofing of structures is not covered by this standard due to the vast number and types used in modern day construction. LPC may also be suitable for use in hazardous atmospheres. Regard shoul d then be taken of the extra requirements necessary for the components to be installed in such conditions.

Specifies the requirements and tests for metallic connection components such as connectors, bonding and bridging components, expansion pieces as well as test joints for Lightning Protection Systems (LPS).
