Lightning protection system components (LPSC) – Requirements for components for isolated LPS
| Published By | Publication Date | Number of Pages |
| BSI | 2018 | 56 |
This document 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.
Testing of insulating stand-offs and insulating down-conductors components for an explosive atmosphere is not covered by this document.
Requirements and tests for other types of components for isolated LPS are under consideration.
