This part of IEC 62561 specifies the requirements and tests for earthing enhancing compounds producing low resistance of an earth termination system.
Lightning protection system components (LPSC) - Part 7: Requirements for earthing enhancing compounds
Technical requirements for lightning protection of radio monitoring stations
Lightning protection system components (LPSC). Requirements for connection components
This part of IEC 62561 deals with the requirements and tests for metallic and non-metallic conductor fasteners that are used to retain and support the air-termination, down-conductor and earth-termination systems. This document does not cover the fixing of conductor fasteners to the fabric of structures due to the vast number and types used in modern day construction. LPSC can also be suitable for use in hazardous atmospheres. There are therefore additional requirements when installing the components in such conditions.
Lightning protection system components (LPSC) - Part 4: Requirements for conductor fasteners
This part of IEC 62561 specifies the requirements and tests for earth electrode inspection housings (earth housing) installed in the earth and for earth electrode seals. Lightning protection system components (LPSC) can also be suitable for use in hazardous atmospheres. There are therefore additional requirements when installing the components under such conditions. NOTE Different requirements and test procedures are given in EN 124 (all parts) and EN 1253 (all parts).
Lightning protection system components (LPSC) - Part 5: Requirements for earth electrode inspection housings and earth electrode seals
This part of IEC 62561 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. 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 power 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 does not cover applications where follow currents occur. NOTE Lightning protection system components (LPSC) can also be suitable for use in hazardous conditions such as fire and explosive atmosphere. Due regard will be taken of the extra requirements necessary for the components to be installed in such conditions.
Lightning protection system components (LPSC) - Part 3: Requirements for isolating spark gaps (ISG)
Calibration specifications for high-voltage testing instruments and equipment Part 5: Zinc oxide arrester resistive current tester
This part of IEC 62561 specifies the requirements and tests for metallic connection components that form part of a lightning protection system (LPS). Typically, these can be connectors, clamps, bonding and bridging components, expansion pieces and test joints. For the purposes of this document the following connection types are considered as connection components: exothermic, brazing, welding, clamping, crimping, seaming, screwing or bolting. Testing of components for an explosive atmosphere is not covered by this document.
