This part of ISO4437 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 part of ISO4437. In conjunction with ISO4437-1, ISO4437-2, ISO4437-3:2014, and ISO4437-5, 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: the maximum operating pressure, MOP, is based on the design stress determined from the compound MRS divided by the C factor and taking into account RCP requirements; temperature of 20°C as reference temperature; NOTE1 For other operating temperatures, derating coefficients are given in ISO4437-5:2014. operating temperature between −20°C and +40°C. This International Standard covers a range of maximum operating pressures and gives requirements concerning colours and additives. NOTE2 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 ends or electrofusion sockets intended to be jointed with PE pipes conforming to ISO4437-2 without any fittings or with PE fittings conforming to ISO4437-3:2014. This part of ISO4437 covers valves for pipes with a nominal outside diameter dn≤400mm. NOTE3 Valves made from materials other than polyethylene designed for the supply of gaseous fuels conforming to the relevant standards are permitted to be used in PE piping systems according to ISO4437 provided that they have relevant PE connections for butt fusion or electrofusion ends (see ISO4437-3). The component, i.e. the complete valve, shall fulfil the requirements of this part of ISO4437.
