35、 BSI EN 13244-4:2002 (E) 5 Introduction EN 13244, of which this is Part 4, specifies the requirements of a piping system and its components when made from polyethylene (PE). It is intended to be used for buried and above-ground pressure systems for water for general purposes, drainage and sewerage,
36、including vacuum systems. Requirements and test methods for material and components, other than valves, are specified in EN 13244-1, EN 13244-2 and EN 13244-3. Characteristics for fitness for purpose are covered in EN 13244-5 and prCEN/TS 13244-7 gives guidance for the assessment of conformity. This
37、 Part of EN 13244 covers the characteristics of valves. Licensed Copy: sheffieldun sheffieldun, na, Sun Oct 29 09:55:00 GMT+00:00 2006, Uncontrolled Copy, (c) BSI EN 13244-4:2002 (E) 6 1 Scope This Part of EN 13244 specifies the characteristics of valves or valve bodies made from polyethylene (PE) i
38、ntended for buried and above-ground pressure systems for water for general purposes, drainage and sewerage. It is also applicable for vacuum sewer systems. NOTE 1Water for general purposes is not intended for human consumption and components conforming to this standard should not be used in systems
39、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 1. NOTE 2Valves made from material other than polyethylene (PE) designed to (a) relevant standard(s) can be used in PE piping sy
40、stems 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 valve
41、s, their joints and to joints with components of other 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 bar1); an operating temperature of 20 C
42、 as a reference temperature. NOTE 3For applications operating at constant temperatures greater than 20 C and up to 40 C, see annex A of EN 13244-1:2002. EN 13244 covers a range of maximum operating pressures and gives requirements concerning colours and additives. NOTE 4It is the responsibility of t
43、he purchaser or specifier to make the appropriate selections from these aspects, taking into account their particular requirements and any relevant national guidance or regulations and installation practices or codes. This Part of EN 13244 covers valves for pipes with a nominal outside diameter dn 2
44、25 mm. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For dated references, subsequent amendments to o
