適用范圍：This part of ISO 4427 specifies the characteristics of the fitness for purpose of assembled piping systemsmade from polyethylene (PE) intended for the conveyance of water for human consumption, including rawwater prior to treatment and water for general purposes.It also specifies the test parameters for the test methods to which it refers.In conjunction with the other parts of ISO 4427, it is applicable to PE pipes, fittings, valves, their joints and tojoints with components of other materials, intended to be used under the following conditions:a) a maximum operating pressure (MOP) up to and including 25 bar1);b) an operating temperature of 20 °C as the reference temperature.NOTE 1 For applications operating at constant temperatures greater than 20 °C and up to 40 °C, see ISO 4427-1:2007,Annex A.NOTE 2 ISO 4427 covers a range of maximum operating pressures and gives requirements concerning colours andadditives. It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, takinginto account their particular requirements and any relevant national guidance or regulations and installation practices orcodes.
