These can be intended for the conveyance of water for human consumption, raw water before treatment, drains and sewers under pressure, vacuum sewer systems, and water for other purposes, except industrial applications.
The intended use includes sea outfalls, laid in water and pipes suspended below bridges. It also specifies the test parameters for the test methods referred to in EN 12201-1.
EN 12201-1 applies to PE pipes, fittings and valves, their joints and joints with components of PE and other materials intended to be used under the following conditions:
– allowable operating pressure, PFA, up to 25 bar,
– an operating temperature of 20 °C as a reference temperature.
The EN 12201 series covers a range of allowable operating pressures and gives requirements concerning colours.
