The standard IEC 62305-3:2024 is the third part of a four-part international series that provides the technical requirements for protecting structures from physical damage caused by lightning. It focuses specifically on the design and maintenance of Lightning Protection Systems (LPS)
Several comprehensive technical guides are available to help navigate the complexities of this standard: Leading Technical Guides (PDFs) DEHN Lightning Protection Guide iec 62305-3 pdf
- The Rolling Sphere Method: This is the most widely recognized visualization in the standard. Depending on your LPL, you use a "sphere" of a specific radius (e.g., 20m for Level I, 60m for Level IV) and roll it across the structure. Anywhere the sphere touches the building requires an air terminal; the "shadow" areas underneath are deemed protected.
- The Mesh Method: For flat surfaces, the standard defines mesh sizes (e.g., 5m x 5m for Level I) to ensure no point is left exposed.
When lightning strikes, it isn't just a flash in the pan—it can carry over 200,000 amperes and reach temperatures five times hotter than the sun’s surface. For anyone managing facilities or designing buildings, the IEC 62305-3 standard is the gold-standard manual for keeping people and structures safe from these physical hazards. What is IEC 62305-3?
