该欧洲标准主要适用于铜合金球阀，尺寸DN 8至DN 100，适用于PN 10建筑物内的饮用水供应，配水温度为65°C。允许高达90°C的偶尔游览时间最长为1小时。 本标准还适用于与同一机构中其他部件组合的球阀。 本标准规定: - 材料的要求和球阀的设计; - 球阀的机械，液压和声学要求; - 验证球阀要求的试验方法; - 球阀的标识要求。 球阀与其他阀门结合应符合相同要求

This European standard applies primarily to copper alloy ball valves, dimensions DN 8 to DN 100, for potable water supply in buildings up to PN 10 and a distribution temperature of 65 °C. Occasional excursions up to 90 °C are permitted for a period of 1 h maximum. This standard applies also to ball valves in combination with other components in the same body. This standard specifies: - the requirements of the materials and the design of ball valves; - the mechanical, hydraulic and acoustic requirements of ball valves; - the test methods to verify the requirements of ball valves; - the marking requirements of ball valves. Ball valves in combination with other valves should fulfil the same requirements.
