Plastics piping systems for water supply - Polyethylene (PE) - Part 4: Valves
This Part of EN 12201 specifies the characteristics of valves or valve bodies made from polyethylene (PE) intended for the conveyance of water intended for human consumption, including raw water prior to treatment. It also specifies the test parameters for the test methods referred to in this standard. NOTE 1 Valves made from material other than polyethylene (PE) designed for the supply of water intended for human consumption to a relevant standard(s) can be used in PE piping systems conforming to prEN 12201 when they have relevant PE connection ends for butt fusion or electrofusion (see prEN 12201-3). In conjunction with other Parts of prEN 12201 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 25 bar; b) an operating temperature of 20 °C as reference temperature. NOTE 2 For applications operating at constant temperatures greater than 20 °C and up to 40 °C, see annex A of prEN 12201-1:1999. prEN 12201 covers a range
