IEC 62561-3:2017 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.
This bilingual version (2018-11) corresponds to the monolingual English version, published in 2017-06.
This second edition cancels and replaces the first edition, published in 2012. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition.
- a new classification has been added related to ISGs location installation;
- an updated flow chart of tests has been developed.
The French version of this document has not been voted upon.
