Frequently Asked Questions

WG 11 is a Technical Committee within the International Electrotechnical Commission (IEC). It is named "TC 81/WG 11". This committee has published 260 standards.

WG 11 develops IEC standards in the area of Information technology. Currently, there are 260 published standards from this technical committee.

The International Electrotechnical Commission (IEC) is the world's leading organization for the preparation and publication of international standards for electrical, electronic, and related technologies. Founded in 1906, the IEC provides a global platform for companies, industries, and governments to meet, discuss, and develop the international standards they require.

A Technical Committee (TC) in IEC is a group of experts responsible for developing international standards in a specific technical area. TCs are composed of national member body delegates and work through consensus to create standards that meet global industry needs. Each TC may have subcommittees (SCs) and working groups (WGs) for specialized topics.

IEC TS 62561-8:2018(Main)
Lightning protection system components (LPSC) - Part 8: Requirements for components for isolated LPS

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.

Lightning protection system components (LPSC) - Part 2: Requirements for conductors and earth electrodes

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(Main)
Lightning protection system components (LPSC) - Part 1: Requirements for connection components

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.

Lightning protection system components (LPSC) - Part 3: Requirements for isolating spark gaps (ISG)

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.

Lightning protection system components (LPSC) - Part 6: Requirements for lightning strike counters (LSC)

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).

Lightning protection system components (LPSC) - Part 5: Requirements for earth electrode inspection housings and earth electrode seals

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.

Lightning protection system components (LPSC) - Part 4: Requirements for conductor fasteners

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.
