What is BS EN 62561-7:2013

BS EN 62561-7:2013 is a technical standard that focuses on the protection against lightning – Part 7: Requirements for earthing enhancing compounds. In simpler terms, it sets out the guidelines and specifications for materials used to improve the effectiveness of electrical earthing systems in buildings and structures.

The Importance of Earthing Systems

Earthing systems are crucial for the safety and functionality of electrical installations. When lightning strikes or there is a power surge, excess electrical energy needs to be safely discharged into the ground. Without proper earthing, this excess energy can cause damage to equipment, start fires, or pose a threat to human lives.

BS EN 62561-7:2013 provides requirements for earthing enhancing compounds, which are substances added to the soil surrounding the earthing system to lower its electrical resistance. By reducing resistance, these compounds help to dissipate electrical energy more effectively, minimizing the potential risks associated with electrical faults.

Specifying and Testing Earthing Enhancing Compounds

The standard specifies various characteristics and performance criteria for earthing enhancing compounds. It covers factors such as chemical composition, particle size, moisture content, electrical resistivity, and long-term stability.

In addition to the specifications, BS EN 62561-7 also outlines testing methods to ensure the quality and compatibility of the compounds. These tests include determining resistivity, corrosion potential, leaching behavior, and mechanical strength.

Compliance and Safety Considerations

Complying with BS EN 62561-7:2013 is essential for manufacturers and installers of earthing enhancement compounds. Meeting the standards ensures that the compounds will perform reliably, improving the safety and efficiency of earthing systems.

By using approved compounds, practitioners can be confident that they are using materials that have been rigorously tested for performance and durability. This not only avoids potential hazards but also contributes to the overall effectiveness and longevity of electrical installations in various industries, including telecommunications, power distribution, and manufacturing facilities.

In conclusion, BS EN 62561-7:2013 sets out guidelines for earthing enhancing compounds to enhance the safety and efficiency of electrical earthing systems. By complying with these standards, manufacturers and installers can ensure that the compounds they use meet the required specifications and provide reliable protection against electrical faults and lightning strikes.
