What is BS EN 62561-5:2013?

Introduction:

BS EN 62561-5:2013 is a technical standard developed by the British Standards Institution (BSI) that pertains to lightning protection systems. This standard provides guidelines for the design, installation, and maintenance of lightning protection measures to ensure the safety of structures and equipment from the damaging effects of lightning strikes. In this article, we will delve into the key aspects of BS EN 62561-5:2013 and its role in safeguarding against lightning-induced risks.

Scope of BS EN 62561-5:2013

The Scope:

The scope of BS EN 62561-5:2013 encompasses various elements necessary for an effective lightning protection system. It covers the classification and performance requirements of air termination systems, down-conductor systems, earth termination systems, and their associated components. The standard also addresses the testing and inspection procedures required to verify the functionality and compliance of these systems.

Key Requirements of BS EN 62561-5:2013

Air Termination Systems:

BS EN 62561-5:2013 mandates that air termination systems should be designed to intercept lightning strikes and provide safe dissipation of the electric current into the ground. It specifies the minimum number and placement of air terminals based on the structure's geometry and its vulnerability to lightning-induced effects. The standard also emphasizes the importance of proper conductor thickness, corrosion resistance, and material durability to ensure reliable performance over an extended period.

Down-conductor Systems:

The standard stipulates that down-conductors must provide low impedance pathways for safely conducting lightning currents from the air terminal systems to the earth termination systems. It outlines essential requirements for conductor materials, dimensions, mechanical strength, routing methods, and bonding techniques to mitigate the risk of structural damage, fire hazards, and side flashes during lightning events.

Compliance and Certification

Testing and Inspection:

BS EN 62561-5:2013 emphasizes the importance of regular testing and inspection of lightning protection systems to ensure continued compliance. It outlines various testing procedures such as resistance measurements, visual inspections, and periodic maintenance checks to assess the system's integrity. Adherence to these testing and inspection requirements is crucial for obtaining certification and ensuring the efficacy of the lightning protection measures implemented.

Certification Bodies:

In order to validate compliance with BS EN 62561-5:2013, specialized certification bodies play a vital role. These independent organizations assess the design, installation, and overall performance of the lightning protection system against the standard's requirements. Certification provides assurance to stakeholders that the system meets recognized industry standards and offers optimal protection against lightning-related risks.

In conclusion, BS EN 62561-5:2013 is a comprehensive technical standard that provides essential guidelines for the design, installation, and maintenance of lightning protection systems. By adhering to this standard, structures can effectively mitigate the risks posed by lightning strikes and safeguard both personnel and critical equipment from potential damage or destruction. Compliance with BS EN 62561-5:2013, coupled with proper testing and certification, ensures that lightning protection measures are reliable and capable of offering the intended level of protection.
