scope:

This Part of EN 13244 specifies the characteristics of valves or valve bodies made from PE intended for buried and above-ground pressure systems for water for general purposes, drainage and sewerage. It is also applicable for vacuum sewer systems. NOTE 1 Water for general purposes is not intended for human consumption and components conforming to this standard shoulc not be used in systems conveying water for human consumption. For PE components intended for the conveyance of water intended for human consumption and raw water prior to treatment, see EN 12201. NOTE 2 Valves made from material other than PE designed to (a) relevant standard(s) can be used in PE piping systems conforming to EN 13244 when they have relevant PE connection ends for butt fusion or electrofusion (see EN 13244-3).It also specifies the test parameters for the test methods referred to in this standard. In conjunction with other Parts of EN 13244 (See Foreword), it is applicable to PE pipes, fittings, valves, their joints and to joints with components of non-plastics materials intended to be used as follows: - buried in the ground; - sea outfalls; - laid in water; - above-ground including pipes suspended below bridges; - a maximum operating pressure, MOP, up to and including 25 bar; - an operating temperature of 20°C as reference temperature. 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 naational guidance of regulations and installation practices or codes.
