Lightning Protection System Components (LPSC) - Part 1: Testing requirements for metal sheets' joints used in LPS
|Publication Date:||1 June 2021|
|ICS Code (Lightning protection):||91.120.40|
This document defines the requirements and testing for joints of metal sheets, with or without insulating coatings, used as natural components in roofs, facades or walls of buildings, suitable to conduct lightning current in LPS where the interconnection of these metal sheets does not ensure durable electrical connection.
NOTE This document does not deal with the lightning interception capabilities of these components. The connection clamps for connecting the metallic sheet with the down conductor to the earth termination system are LPSC, tested according to EN 62561-1.
