Lightning strikes present a severe threat to structures, human lives, and electronic systems. To mitigate these risks, the International Electrotechnical Commission developed the IEC 62305 standard series. Within this framework, focuses specifically on protecting structures against physical damage and guarding living beings against injury due to touch and step voltages.
Systems deployed in explosive environments or highly corrosive areas should undergo complete inspections every year. Sourcing the Official IEC 62305-3 PDF

National standards bodies (such as BSI in the UK, DIN in Germany, or ANSI in the United States). iec 62305-3 pdf
The complete IEC 62305 standard consists of four distinct parts, each addressing a specific dimension of lightning protection:
IEC 62305-3 is titled "Protection against lightning - Part 3: Physical damage to structures and life hazard." This standard specifically addresses the protection of structures against lightning strikes, focusing on the physical damage that can occur due to the strike itself and the subsequent effects like fires or explosions. The standard outlines measures to mitigate these risks, ensuring the safety of people and the integrity of structures.
Where direct bonding isn't possible (such as live power and telecommunication lines), SPDs must be installed to safely clamp voltage surges. 4. Lightning Protection Levels (LPL) Lightning strikes present a severe threat to structures,
An LPS degrades over time due to weather exposure, corrosion, and structural alterations. The standard mandates structured inspection cycles:
: The PDF is regularly updated to reflect the latest research, technologies, and best practices in lightning protection.
Localized adoptions, such as the or DIN EN 62305-3 publications, which contain identical technical requirements translated for regional governance. The standard outlines measures to mitigate these risks,
