What is BS EN 61386?

BS EN 61386 is a technical standard that relates to circular conduit systems used for electrical installations. This standard provides requirements and test methods for the performance, dimensions, and marking of rigid non-metallic conduit systems.

Performance Requirements

BS EN 61386 sets out specific performance requirements that non-metallic conduit systems must meet. These include factors such as impact resistance, stiffness, and resistance to compression. The standard also covers attributes such as resistance to heat distortion and ultraviolet (UV) light exposure, which are crucial for outdoor installations.

Dimensions and Marking

The standard further defines the dimensions and markings required for non-metallic conduit systems. It specifies the range of sizes available and the minimum wall thicknesses that should be maintained. Additionally, BS EN 61386 sets guidelines for marking the conduit systems with relevant information such as manufacturer details, product identification codes, and applicable standards compliance.

Testing Methods

BS EN 61386 outlines the testing methods used to determine whether a conduit system meets the standard's requirements. These methods help ensure that manufacturers consistently produce conduit systems that are safe and reliable. Some of the common tests conducted involve subjecting samples to various environmental conditions, such as thermal cycling, water immersion, and mechanical impact. These tests validate the conduit systems' ability to withstand these challenging conditions and demonstrate their long-term durability.

In conclusion, BS EN 61386 is an essential technical standard governing circular conduit systems used in electrical installations. By complying with this standard, manufacturers can provide products that meet specific performance requirements, adhere to defined dimensions, and feature appropriate markings. Through rigorous testing methods, the standard ensures that these conduit systems are capable of handling challenging environments and withstand the test of time.
