EN 50086-2-4 Conduit Systems, Cable Management Underground

EN 50086-2-4 defines specifications for cable management in conduit systems. This method is used to investigate conduit systems buried underground for the protection and management of insulated conductors and/or cables in electrical or communication systems. The test method is suitable for use with a range of materials, including metallic, non-metallic, and composites. The test specimen is compressed along its major axis at a constant rate of displacement until one of the three end of test criteria is reached:

• Specimen fractures which causes a drop in force
• A predetermined force value is reached
• Or, a predetermined displacement is reached
