What is BS EN 62305-2:2018?

The BS EN 62305-2:2018 is a technical standard that provides guidance and requirements for the design, installation, and maintenance of lightning protection systems. The standard was developed by the British Standards Institution (BSI) in collaboration with experts from various industries.

Scope and Purpose

This technical standard is applicable to structures and buildings of all kinds, including residential, commercial, industrial, and public buildings. It aims to protect these structures from the damaging effects of lightning strikes by providing effective lightning protection measures.

The purpose of BS EN 62305-2:2018 is to ensure the safety of people, as well as the functionality and integrity of electrical and electronic systems within a structure during and after a lightning strike.

Key Requirements

The standard outlines several key requirements that must be taken into consideration when designing and installing a lightning protection system:

1. Risk Assessment: A thorough assessment of the structure and its surroundings must be conducted to determine the level of risk posed by lightning strikes. This includes considering factors such as the structure's location, height, occupancy, and nature of activities carried out inside.

2. Protection Measures: Based on the risk assessment, appropriate protection measures need to be implemented. These may include air terminals (lightning rods), down conductors, bonding and grounding systems, surge protection devices, and equipotential bonding.

3. Design Considerations: The design of the lightning protection system should take into account factors such as the type of structure, its materials, structural elements, and external features. It should also consider existing electrical and electronic systems within the structure to ensure their compatibility and proper functioning.

Implementation and Maintenance

Once the lightning protection system is designed and installed, regular maintenance and inspections should be conducted to ensure its effectiveness. This includes periodic testing of the system and repairing any damaged or faulty components. It is essential to adhere to the guidelines provided in BS EN 62305-2:2018 to maintain a safe and reliable lightning protection system.

In conclusion, BS EN 62305-2:2018 is a technical standard that provides comprehensive guidance for the design, installation, and maintenance of lightning protection systems. By following this standard, structures and buildings can be protected from the damaging effects of lightning strikes, ensuring the safety of occupants and the integrity of electrical and electronic systems.
