What is BS EN 62561-8:2018

BS EN 62561-8:2018 is a technical standard defined by the British Standards Institution (BSI) concerning lightning protection systems. The standard provides guidelines for selecting and installing surge protective devices (SPDs) in these systems. This article aims to provide a thorough understanding of BS EN 62561-8:2018, its key concepts, requirements, and implications.

of BS EN 62561-8:2018

BS EN 62561-8:2018 focuses on surge protective devices used in conjunction with external lightning protection systems, commonly referred to as lightning rods. These devices protect structures from transient overvoltages caused by direct lightning strikes or nearby atmospheric discharges. The standard specifies requirements and testing methods for SPDs, ensuring their effectiveness and reliability in safeguarding against lightning-related damage.

Key Concepts and Requirements

The implementation of BS EN 62561-8:2018 involves several key concepts and requirements. Firstly, the standard emphasizes the importance of risk assessment in determining the appropriate level of protection for a specific structure. This includes evaluating factors such as the structure's location, size, and usage. Based on this assessment, a zone-based approach is adopted, dividing the structure into different zones according to the expected exposure to lightning strikes.

Furthermore, BS EN 62561-8:2018 introduces the concept of coordination levels, which aim to establish compatibility between different components of the lightning protection system. The coordination levels ensure that SPDs operate effectively alongside other elements like lightning rods, grounding systems, and electrical installations. Additionally, the standard specifies requirements for environmental conditions, mechanical strength, and electrical performance of SPDs to ensure their durability and functionality in various situations.

Implications of BS EN 62561-8:2018

BS EN 62561-8:2018 has significant implications for architects, engineers, and professionals involved in the design and installation of lightning protection systems. Compliance with the standard ensures that structures are adequately protected against lightning strikes, minimizing the risk of damage to property, electrical systems, and even human lives. Additionally, adherence to BS EN 62561-8:2018 enhances the overall safety standards of buildings, providing peace of mind for occupants and owners alike.

Moreover, as the standard stipulates precise guidelines for selecting and installing SPDs, it promotes consistency and interoperability among different lightning protection systems. This not only simplifies the decision-making process for professionals but also facilitates adequate maintenance and future upgrades of these systems.

In conclusion, BS EN 62561-8:2018 plays a crucial role in ensuring effective lightning protection systems. By addressing various aspects related to surge protective devices, this standard enhances the safety and resilience of structures in the face of lightning-induced risks.
