What is BS EN 61386-7:2011?

BS EN 61386-7:2011 is a technical standard that provides specifications for conduit systems used in electrical installations. Conduit systems are designed to protect and route electrical wiring in buildings, ensuring safety and efficiency. This standard specifically focuses on the requirements for conduits made from unplasticized polyvinyl chloride (PVC-U) with plain ends. It covers various aspects such as dimensions, material properties, and installation techniques.

Specifications and Requirements

The standard sets out clear specifications and requirements for PVC-U conduit systems, aiming to ensure uniformity and compatibility among different manufacturers and suppliers. It includes details about the range of sizes and lengths available, wall thickness, and allowable tolerance levels. BS EN 61386-7:2011 also outlines the mechanical properties of the conduit, including its resistance to impact, bending, and crushing. These requirements are crucial to ensure the conduit's durability and ability to withstand various environmental conditions.

Installation Guidelines

In addition to the specifications, BS EN 61386-7:2011 provides guidelines for the correct installation of PVC-U conduit systems. It covers essential aspects such as the recommended methods for cutting and joining conduit sections, as well as the appropriate fittings and accessories to use. The standard emphasizes the importance of proper fixing and support of the conduit, considering factors such as load capacity, temperature variations, and fire resistance. Adhering to these guidelines helps guarantee the integrity of the installed conduit system.

Evaluating Compliance

To ensure adherence to the standard, BS EN 61386-7:2011 specifies testing and evaluation procedures for assessing the performance of conduit systems. Manufacturers and suppliers follow these procedures to validate their products before they reach the market. Compliance with the standard helps electrical contractors and installers identify reliable and certified products that meet the required safety and performance criteria. Regular inspections and audits can also be conducted to ensure ongoing compliance throughout the lifespan of the conduit system.
