What is BS EN 62561-8:2013?

BS EN 62561-8:2013 is a technical standard that provides guidelines for the design, installation, and maintenance of lightning protection systems (LPS) using metallic conducting materials. This standard specifically focuses on the requirements for assessing the corrosion risks associated with these systems.

Importance of BS EN 62561-8:2013

Lightning strikes can cause significant damage to buildings and infrastructure if not properly protected. To mitigate the risks associated with lightning strikes, lightning protection systems are installed. However, these systems are exposed to various environmental conditions, including corrosive elements such as moisture and chemicals, which can impact their effectiveness over time.

BS EN 62561-8:2013 sets out the principles for ensuring the long-term performance and durability of lightning protection systems. By complying with this standard, it becomes possible to assess the corrosion risks associated with different environmental conditions and choose appropriate corrosion protection measures to ensure the system's continued effectiveness.

Key Requirements of BS EN 62561-8:2013

The standard outlines several key requirements that must be considered when designing and maintaining a lightning protection system:

Corrosion Risk Assessment: The standard provides a methodology for assessing the corrosion risk based on environmental conditions, materials used, and maintenance practices. Understanding the level of corrosion risk helps in selecting appropriate materials and protective measures.

Material Selection: BS EN 62561-8:2013 provides guidance on selecting suitable materials for lightning protection systems that can withstand the expected corrosion levels. It outlines factors like corrosion resistance, mechanical strength, and electrical conductivity that should be considered during material selection.

Design Considerations: The standard highlights various design considerations that need to be taken into account for an effective lightning protection system. This includes the proper bonding of conductors, minimizing the use of dissimilar metals, and maintaining proper clearances for electrical connections.

Maintenance and Inspection: Regular inspection and maintenance of lightning protection systems are crucial for ensuring their continued performance. BS EN 62561-8:2013 provides guidelines for the frequency of inspections, maintenance procedures, and documentation requirements to maintain compliance.


BS EN 62561-8:2013 plays a vital role in ensuring the effectiveness and longevity of lightning protection systems by addressing corrosion risks associated with these systems. By following this standard, designers, installers, and maintainers of lightning protection systems can make informed decisions regarding material selection, design considerations, and maintenance practices, ultimately enhancing the safety of buildings and infrastructure.
