The NFC 17-102:2011 standard and the IEC 62305 standard represent two different approaches in the field of lightning protection, each with its own specifications and recommendations. Here is a summary of the main differences between these two standards:
NFC 17-102:2011
Application domain :
This French standard mainly focuses on the design, installation and maintenance of Early Streamer Emitter Lightning Rod (ESE).
Technology :
It is specifically geared towards the use of ESEs, which are designed to initiate the lightning capture process faster than traditional capture heads, thanks to an active initiation mechanism.
Application :
Although it can be applied to various types of structures, it is often preferred for the protection of isolated structures, of significant heights, or with specific lightning protection needs.
IEC 62305
Application domain :
This series of international standards provides a comprehensive framework for lightning protection, covering risk analysis, physical protection of structures and surge protection for electrical and electronic equipment.
Technology :
IEC 62305 takes a more comprehensive approach, integrating both external protection systems (e.g. conventional catch rods) and internal protection systems (surge protection).
Application :
It is applicable to a wide range of structures, from residential buildings to complex industrial installations, providing guidelines for comprehensively assessing and mitigating lightning risks.
The selection of which standard to apply depends on several factors, including the type of structure to be protected, local regulatory requirements, and specific lightning protection objectives. It is important to consult a lightning protection expert to determine the best approach for a given project.
