It also specifies the test parameters for the test methods referred to in this standard. In conjunction with Parts 2 to 5 of EN 12201, it is applicable to PE pipes, fittings, valves, their joints and to joints with components of 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; c) buried in the ground; d) sea outfalls; e) laid in water; f) above ground, including pipes suspended below bridges. EN 12201 (all parts) covers a range of allowable operating pressures and gives requirements concerning colours and additives.
