WG 11 - TC 81/WG 11

IEC/TS 62561-8:2018 specifies the requirements and tests for insulating stand-offs, used in conjunction with an air-termination system and down-conductors with the aim of maintaining the proper separation distance, and the requirements and tests for insulating down‑conductors, including their specific fasteners, able to reduce the separation distance.

IEC 62561-2:2012 specifies the requirements and tests for:
- metallic conductors (other than "natural" conductors) that form part of the air termination system and down conductors;
- metallic earth electrodes that form part of the earth termination system.

IEC 62561-1:2012 specifies the requirements and tests for metallic connection components that form part of a lightning protection system (LPS). Typically, these can be connectors, bonding and bridging components, expansion pieces and test joints. Testing of components for an explosive atmosphere is not covered by this standard.

IEC 62561-3:2012 specifies the requirements and tests for isolating spark gaps (ISG) for lightning protection systems. ISGs can be used to indirectly bond a lightning protection system to other nearby metalwork where a direct bond is not permissible for functional reasons.

IEC 62561-7:2011 specifies the requirements and tests for earthing enhancing compounds producing low resistance of an earth termination system.

IEC 62561-5:2011 specifies the requirements and tests for
- earth electrode inspection housings (earth pit),
- earth electrode seals.
Lightning protection system components (LPSC) may also be suitable for use in hazardous atmospheres. Regard should then be taken of the extra requirements necessary for the components to be installed in such conditions.

IEC 62561-6:2011 specifies the requirements and tests for devices intended to count the number of lightning strike pulses flowing in a conductor. This conductor may be part of a lightning protection system (LPS) or connected to an SPD installation (or other conductors which are not intended to conduct a significant portion of lightning currents).

IEC 62561-4:2010 deals with the requirements and tests for metallic and non-metallic conductor fasteners that are used in conjunction with the air termination, down conductor and earth termination system. This standard does not cover the fixing of conductor fasteners to the fabric/membrane/gravel roofing of structures due to the vast number and types used in modern day construction. LPSC may also be suitable for use in hazardous atmospheres. Regard should then be taken of the extra requirements necessary for the components to be installed in such conditions.
