标准摘要
[中文适用范围]： 本文件规定了用于控制供水设备中水流、压力或温度的直通阀门和设备在测量水流产生的噪声排放时应使用的安装和操作条件。它适用于最大公称尺寸为 DN 32 的直通阀门和设备，以及最大水流量不超过 1.6 l/s 的系统。注：参见 ISO 6708；DN 是“公称尺寸”的符号。公称尺寸的数字与直通阀门和设备的内径（以毫米为单位）大致相关。所述程序一般适用于所有类型的常规设计直通阀门。 [外文原描述]： ISO 3822-3:2018 specifies the mounting and operating conditions to be used for in-line valves and appliances which control the flow, pressure or temperature of the water in water supply installations, when measuring noise emission resulting from water flow. ISO 3822-3:2018 is applicable to in-line valves and appliances of maximum nominal size DN 32 and to systems in which the maximum water flow rate does not exceed 1,6 l/s. NOTE See ISO 6708; DN is the symbol for "nominal size". The number of the nominal size is loosely related to the inside diameter (in millimetres) of the in-tine valves and appliances. The procedures described are for general use for all types of in-line valves of conventional design.
