EN 12288:2003 (E)41 ScopeThis European Standard applies to copper alloy gate valves for general use having flanged, threaded,capillary, compression or loose nut/union body ends.This standard specifies the design and performance requirements including materials, pressure/temperatureratings, dimensions, test procedures and marking.For some specific fields of application, for example, drinking water or gas, valves to this standard can be usedprovided the requirements of the relevant performance standards are met. Approval by the relevant regulatorybody may be required.The range of nominal sizes is DN 8 to DN 500 and of nominal diameters is 8 mm to 110 mm.The range of pressure designations covered is PN 6 ; PN 10 ; PN 16 ; PN 20 ; PN 25 ; PN 32 ; PN 40 ; PN 63; Class 150 and Class 300.For the applicability of each nominal size/diameter and each pressure designation to the different types ofvalve end, see 4.1.2 Normative referencesThis 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 listedhereafter. For dated references, subsequent amendments to or revisions of any of these publications apply tothis European Standard only when incorporated in it by amendment or revision. For undated references thelatest edition of the publication referred to applies (including amendments).EN 19:2002, Industrial valves — Marking of metallic valvesEN 558-1, Industrial valves — Face-to-face and centre-to-face dimensions of metal valves for use in flangedpipe systems — Part 1: PN-designated valvesEN 558-2, Industrial valves — Face-to-face and centre-to-face dimensions of metal valves for use in flangedpipe systems — Part 2: Class-designated valvesEN 736-1:1995, Valves — Terminology — Part 1: Definition of types of valvesEN 736-2:1997, Valves — Terminology — Part 2: Definition of components of valvesEN 736-3:1999, Valves — Terminology — Part 3: Definition of termsEN 1057, Copper and copper alloys — Seamless round copper tubes for water and gas in sanitary andheating applicationsprEN 1092-31), Flanges and their joints — Circular flanges for pipes, valves, fittings and accessories, PNdesignated — Part 3: Copper alloy flanges,EN 1254-1, Copper and copper alloys — Plumbing fittings — Part 1: Fittings with ends for capillary solderingor capillary brazing to copper tubes
