This European Standard shall be given the status of a national standard, either by publicatio
17、n of an identical text or by endorsement, at the latest by January 2004, and conflicting national standards shall be withdrawn at the latest by January 2004. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports
18、essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this Europ
19、ean Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Slovakia, Spain, Sweden, Switzerland and the United Kingdom. A European Acceptance Scheme, which will permit products manufac
20、tured for use in drinking water applications to be CE marked, is under development. Annexes A and B are normative. EN 12288:2003 (E) 4 1 Scope This European Standard applies to copper alloy gate valves for general use having flanged, threaded, capillary, compression or loose nut/union body ends. Thi
21、s standard specifies the design and performance requirements including materials, pressure/temperature ratings, dimensions, test procedures and marking. For some specific fields of application, for example, drinking water or gas, valves to this standard can be used provided the requirements of the r
22、elevant performance standards are met. Approval by the relevant regulatory body 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
23、 150 and Class 300. For the applicability of each nominal size/diameter and each pressure designation to the different types of valve end, see 4.1. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references
24、 are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision.

Capillary and compression end valves are normally identified by nominal diameter expressed as the nominal
39、 outside diameter of the connecting tube or pipe. The use of DN for valves with body ends other than flanged is permitted.
