In 1995/96 the new European standards for Flexible & Pliable Conduit systems BS EN 50086-2-3 and BS EN 50086-2-2 were published by BSI. This was the first European standard for Flexible & Pliable Conduit systems:
The standard was written to conform to the Low Voltage Directive (LVD) and with the Essential Requirements of the Construction Products Directive (CPD) in mind.
As required by the CENELEC rules it was written in the style of a performance standard.
In November 2004 this standard was superceded by the new IEC61386 parts 1, 2.2 (pliable conduit) and 2.3 (flexible conduit). This is essentially the same standard but with some improvement and updates to the impact and fire testing. EN50086 remains in force until August 2007 when it will be fully replaced by IEC61386. IEC61386 is now live and all conduit manufacturers should be testing and certifying to the new standard.
There are few references to dimensions in the standard. The standard identifies key product characteristics such as: mechanical strength, temperature, electrical properties, resistance to ingress of solids and water, corrosion resistance and fire performance.
For each of these characteristics there are recommended tests as well as a range of performances. The purchaser must decide which performance against each characteristic is appropriate for his installation.
