This Part of EN 12201 specifies the characteristics of valves or valve bodies made from polyethylene (PE 100 and PE 80) for buried and above ground applications, intended for the conveyance of water for human consumption, raw water prior to treatment, drainage and sewerage under pressure, vacuum sewer systems, and water for other purposes. NOTE 1 For valves or valve bodies intended for drainage and sewerage under pressure, additional specifications/tests may be necessary according to the requirements of the purchaser, especially for the chemical resistance of the components in contact with the fluids and functioning characteristics. NOTE 2 For PE components intended for the conveyance of water for human consumption and raw water prior to treatment attention is drawn to 5.4. Components manufactured for water for other purposes may not be suitable for water supply for human consumption. It also specifies the test parameters for the test methods referred to in this European Standard.NOTE 3 Valves made from material other than polyethylene (PE) designed for the supply of water intended for human consumption to a relevant standard(s) can be used in PE piping systems conforming to EN 12201 when they have relevant PE connection for butt fusion or electrofusion ends (see EN 12201-3:2011). In conjunction with Parts 1, 2, 3 and 5 of EN 12201 it is applicable to PE valves, their joints and to 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 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. NOTE 4 For applications operating at constant temperature greater than 20 °C and up to 40 °C, see EN 12201-1:2011, Annex A.
