PVC-Oriented is the second generation of PVC-Unplasticized. Molecular orientation of PVC-U pipes results in a strong improvement of the physical and mechanical properties. The new draft European standard for PVCoriented plastic piping systems is based on the ISO 16422 “Pipes and joints made out of oriented unplasticized poly(vinyl)chloride (PVC-O) for the conveyance of water under pressure – Specification’s” . This new draft EN standard is set up as a system standard containing specifications for pipes, fittings and the fitness for purpose of the system.
BSTRACT The European Plastic Pipes and Fittings Association TEPPFA has taken the initiative to prepare a European draft standard based next to ISO 16422 on existing national specifications in France, Spain, United Kingdom and the Netherlands.
The draft EN standard is intended to be used for temperatures to 45°C, working pressures up to 25 bars and for the following applications:
- Water mains and service buried in the ground;
- Conveyance of water above ground for both outside and inside buildings;
- Drainage and sewerage systems under pressure
- Irrigation under pressure.

In the late nineties a study of the behavior of buried thermoplastics pipes was carried out. The project had input and participants from both the plastic pipe industry as well as from external organizations. Six external leading experts in the field of pipeline design, not necessarily plastics pipes design, have been...

For controlled water disinfection, typically chlorine is used and preliminary studies demonstrate its aging and crack growth acceleration effects on polyolefin pipe materials [1, 2]. Although the use of recycled plastics is not prohibited in some ISO standards for polyolefin piping systems [3–5], only small amounts...
