Designers must prevent bi-metallic contact (e.g., copper touching aluminum directly) to avoid galvanic corrosion. Inspection and Maintenance
(defined by the LPL) is rolled over the structure. Any point that touches the sphere requires protection.
The installation of internal lightning protection (lightning equipotential bonding and electrical isolation).
Inspections include for loose connections or corrosion, and physical testing to measure earthing resistance. The frequency of inspection ranges from 1 to 4 years, depending on the LPL and environmental factors. How to Access the Official IEC 62305-3 PDF iec 62305-3 pdf
The influence of IEC 62305-3 extends globally, as most countries either adopt the standard directly or use it as the technical basis for their own national standards. This ensures a harmonized approach to lightning protection worldwide.
Rods or mesh that "catch" the lightning.
Disperses the lightning current into the ground. IEC 62305-3 details two arrangements: Designers must prevent bi-metallic contact (e
The down-conductor connects the air-termination to the earth-termination.

The standard, titled "Protection against lightning – Part 3: Physical damage to structures and life hazard," is the definitive international guideline for designing and installing Lightning Protection Systems (LPS). The latest edition, IEC 62305-3:2024 , was released in September 2024, replacing the 2010 version with critical updates on component selection and protective measures. Core Objective of IEC 62305-3
) must be maintained between the LPS conductors and the metal object. IEC 62305-3 provides specific formulas to calculate this distance based on the material insulation properties and the current division factor ( 5. Protection Against Life Hazards
