This document specifies the characteristics of fusion fittings made from polyethylene (PE) as well as of mechanical fittings for buried and above ground applications, intended for the conveyance of water for human consumption, raw water prior to treatment, drains and sewers under pressure, vacuum sewer systems, and water for other purposes, with the exception of industrial application
The intended uses include sea outfalls, laid in water and pipes suspended below bridges.
It also specifies the test parameters for the test methods referred to in this document.
In conjunction with EN 12201-1, EN 12201-2, EN 12201-4 and EN 12201-5, this document is applicable 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:
a) allowable operating pressure, PFA, up to 25 bar 1;
b) 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.
These fittings can be of the following types:
- electrofusion socket fittings;
- electrofusion saddle fittings;
- spigot end fittings (for butt fusion using heated tools and electrofusion socket fusion);
- socket fusion fittings (see Annex A);
- mechanical fittings;
- fabricated fittings (see Annex B).
