ISO 16902-1:2003根据ISO 9614-1和ISO 9614-2建立了一个测试代码，用于在受控安装和运行条件下确定液压流体动力泵的声功率级。声功率级将包括测量表面内任何管道辐射的声功率。ISO 16902-1:2003适用于为比较通常用于将旋转机械动力转换为液压流体动力的任何类型泵的空气噪声级提供基础，包括阀门、电磁阀、驱动齿轮、联轴器或任何其他正常安装在使用中的辅助装置。

ISO 16902-1:2003 establishes a test code based on ISO 9614-1 and ISO 9614-2 for determining the sound power levels of a hydraulic fluid power pump under controlled conditions of installation and operation. The sound power level will include sound power radiated by any piping within the measurement surface. ISO 16902-1:2003 is suitable for providing a basis for comparing the airborne noise levels of any type of pump that is normally used to convert rotary mechanical power to hydraulic fluid power, incorporating valves, solenoids, drive gears, couplings or any other auxiliary device normally fitted in service.
