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.
Composants de système de protection contre la foudre (CSPF) - Partie 8: Exigences pour les composants de système isolé de protection contre la foudre
L'IEC/TS 62561-8:2018 précise les exigences et les essais pour les supports isolants employés avec un dispositif de capture et des conducteurs de descente afin de maintenir une distance de séparation appropriée ainsi que les exigences et les essais pour les conducteurs de descente isolants, y compris leurs fixations spécifiques, visant à réduire la distance de séparation.
