The following bibliographic material is provided to assist you with your purchasing decision:
This !European Standard" specifies the characteristics of fittings made from polyethylene (PE 100 and PE 80) 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 PE components intended for the conveyance of water for human consumption and raw water prior to treatment, attention is drawn to 5.6 of this part of EN 12201. Components manufactured for water for other purposes, drainage and sewerage may not be suitable for water supply for human consumption. It also specifies the test parameters for the test methods referred to in this standard. In conjunction with Parts 1, 2 ,4 and 5 of EN 12201, it is applicable to PE fittings, 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 2 For applications operating at constant temperature greater than 20 °C and up to 40 °C, see Annex A of EN 12201-1:2011. EN 12201 (all parts) covers a range of allowable operating pressures and gives requirements concerning colours and additives. NOTE 3 It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, taking into account their particular requirements and any relevant national guidance or regulations and installation practices or codes. These fittings can be of the following types: a) fusion fittings; 1) electrofusion fittings; 2) spigot end fittings (for butt fusion using heated tools and electrofusion socket fusion); 3) socket fusion fittings (see Annex A); b) mechanical fittings; 1) compression fittings; 2) flanged fittings; c) fabricated fittings (see Annex B).
