17、be used without restriction in any of the Member States of the EU or EFTA; 2) It should be noted that, while awaiting the adoption of the verifiable European criteria, existing national regulations concerning the use and/or the characteristics of this product remain in force I Scope The purpose of t

18、his standard EN 121 3 is to specify: - the requirements for the materials and the design of stopvalves; - the mechanical, hydraulic and acoustic requirements; -the test methods; - the marking requirements; for copper alloy stopvalves for use with drinking water supply in buildings. This standard app

19、lies primarily to copper alloy stopvalves, dimensions DN 10 to DN 100, for potable water supply in buildings up to PN 10 and a distribution temperature of 65 “C. Occasional excursions up to 95 “C are permitted for a period of I h maximum. Other metallic materials can be used if it can be verified th

20、at they are suitable for the application. This standard applies also to stopvalves in combination with accessories in the same body. This standard does not apply to regulating or servicing valves, designed specially to isolate sanitary tapware or other sanitary appliances. O BSI 02-2000 Page 5 EN 12
