The European Plastic Pipe and Fittings Association (TEPPFA) has issued the first European EN standard for oriented unplasticised poly(vinyl chloride) (PVC-O) pipes.
The new voluntary standard will create a Europe-wide standard for companies manufacturing PVC-O pipes, where previously there had been a variety of non-aligned national standards.
This new standard allows specification for PVC-O piping systems intended for water supply use, pressurised (up to 25 bar) drainage, sewerage, treated waste water and irrigation systems, either underground or above-ground where protected from direct sunlight. It applies to drinking water piping systems under pressure, up to and including 45°C, as well as to pressurised waste water and irrigation.
The standards include the requirements for the raw material, PVC-O pipes and fittings and their testing to fit for the designed purpose of the system.
Monica de la Cruz is Chair of CEN/TC 155 the European Standardization Committee for Plastic piping systems and ducting systems where this new standard was developed. She commented: “TEPPFA has been instrumental in helping to bring this new standard into being and it will provide reassurance to specifiers that PVC-O pipes and fittings defined within the standard are of a good quality and fit for their designed purpose. Oriented PVC is a remarkably strong material and ideal for a wide variety of applications under pressure to contribute to improve Europe’s water supply and waste water infrastructures.”
TEPPFA is a partner organization of CEN/TC 155 and has been involved in the development of many of the 221 CEN/TC 155 standards currently in use, as well as over 40 projects that are presently being worked on.
