適用范圍：This part of EN 1555 specifies the characteristics of valves made from polyethylene (PE) for piping systems inthe field of the supply of gaseous fuels.NOTE 1 Valves made from other material than polyethylene designed for the supply of gaseous fuels conforming to therelevant standards are permitted to be used in PE piping system according to EN 1555 provided they have relevant PEconnection for butt fusion or electrofusion ends (see EN 1555-3).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 withcomponents 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;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 concerningcolours 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 regulations and installation practices or codes.It is applicable to bi-directional valves with spigot end or electrofusion socket intended to be fused with PEpipes 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.
