Introduction IEC 62305-3 is the third part of the international standard series IEC 62305, which governs protection against lightning. While the overall series addresses risk management, physical damage and life hazard, and electrical and electronic systems within structures, Part 3 focuses specifically on physical damage to structures and life hazard. It provides the methodology and technical provisions for assessing lightning risk to buildings and people, and for designing structural protections (primarily lightning protection systems — LPS) to reduce that risk to an acceptable level.

The building's lightning protection system (LPS) had been installed according to the IEC 62305-3 standard, which provides guidelines for the design, installation, and maintenance of lightning protection systems. The LPS had successfully diverted the lightning strike away from the building, protecting its occupants and preventing a potentially disastrous fire.
IEC 62305-3 sets the international standard for designing, installing, and inspecting lightning protection systems to prevent physical damage to structures and danger to life. It mandates specific requirements for external protection, such as air-termination and down-conductor systems, and internal protection, primarily focusing on equipotential bonding to avoid dangerous sparking. The official standard, necessary for calculating separation distances and air terminal placement, is available through the IEC Webstore and national standards bodies.

A lightning protection system must remain functional throughout its lifespan. IEC 62305-3 outlines rigorous testing intervals based on the assigned LPL.
