Plastics piping systems for buried cable ducting - Unplasticized poly(vinyl chloride) (PVC-U) - Specifications for pipes, fittings and the system

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.
NOTE 1 It is the responsibility of the purchaser or specifier to make the appropriate selection from these aspects, taking into account their particular requirements and any relevant national regulations and installation practices or codes.
prEN 14280 is applicable to solid-wall PVC-U pipes of the following types:
· with plain ends;
· with integral or sleeve type cemented solvent cement socket;
· with integral tapered push-fit socket;
· with integral ring seal socket.
Pipes having a coating for internal lubrication, a colour coating or a coating for other identification purposes are covered by this standard. Multi-layer pipes are not subject of this standard.
The fittings can be manufactured by injection-moulding or be fabricated from pipes and/or mouldings.
Pipes and fittings with nominal outside diameters specified in Annex A are to be tested in accordance with this standard.
