原名S75。07-1997. 定义实验室测试和测量通过控制阀及其相关管道（包括固定流量限制）的可压缩流体辐射的空气传播声音的设备、方法和程序。试验可在用户和制造商商定的任何条件下进行。尽管本标准旨在测量阀门下游管道辐射的噪声，但其他试验变化是可选的，包括使用绝缘和非标准管道。本标准不适用于直接排放到大气中的控制阀。

Formerly S75.07-1997. Defines equipment, methods, and procedures for the laboratory testing and measurement of airborne sound radiated by a compressible fluid flowing through a control valve and its associated piping, including fixed-flow restrictions. The test may be conducted under any conditions agreed upon by the user and the manufacturer. Although this standard is designed for measurement of noise radiated from the piping downstream of the valve, other test variations are optional, including the use of insulation and nonstandard piping. Applications of this standard to control valves discharging directly to the atmosphere are excluded.
