DIN 30691:2024-12

This standard specifies requirements for testing electrically conductive gaskets in flange connections in accordance with DIN EN 62561-1, which are to be used as lightning protection system components. Gaskets that have been successfully tested in accordance with this standard can be used in the construction of a lightning protection system (LPS) designed and implemented in accordance with the DIN EN 62305 series of standards. The prerequisite for the use of gaskets in gas installations is that they meet the requirements specified in DIN 30690-1. Electrically conductive gaskets are metallic connecting components similar to connection and bridging components within the meaning of DIN EN 62561-1. The tests described in this standard are carried out on a test arrangement according to structure B9, Annex B of DIN EN 62561-1. Upon successful testing and proper installation, the flange connection, including the gasket with lightning current carrying capacity, meets the minimum requirements for equipotential bonding for installations in potentially explosive atmospheres in accordance with DIN EN 60079-14.
