This part of EN 1555 specifies the characteristics of valves made from polyethylene (PE) for piping systems in the field of the supply of gaseous fuels. It also specifies the test parameters for the test methods referred to in this standard. In conjunction with Parts 1, 2, 3 and 5 of EN 1555, 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) a maximum operating pressure, MOP, up to and including 10 bar 1); b) an operating temperature of 20 °C as reference temperature; NOTE 2 For other operating temperatures, derating coefficients should be used, see EN 1555-5. c) an operating temperature between -20 °C and +40 °C. EN 1555 (all parts) covers a range of maximum operating pressures and gives requirements concerning colours and additives. It is applicable to bi-directional valves with spigot end or electrofusion socket intended to be fused with PE pipes conforming to EN 1555-2 without any fittings or with PE fittings conforming to EN 1555-3. This European Standard covers valves for pipes with a nominal outside diameter dn ≤ 315 mm.
