scope:

This European Standard specifies the requirements for pipes, fittings and the system of unplasticized poly(vinyl chloride) (PVC-U) solid-wall piping systems intended to be used for buried cable ducting, including the installation on bridge constructions and of river crossings, for the protection of cables in the field of telecommunications and electric energy (low and high voltage) and other services. prEN 14280 is applicable to PVC-U pipes and fittings where cables or ropes may be inserted into the piping system by air pressure. It also specifies the test parameters for the test methods referred to in this standard. For conduit systems buried underground for electrical installations EN 50086-2-4:1993 applies as well. prEN 14280 is applicable to PVC-U pipes and fittings, their joints and to joints with components of other plastics and non-plastics materials intended to be used for buried cable ducting. This standard covers a range of nominal sizes and gives recommendations concerning colours.
