规定了测试回路中使用的阀门的方法，以确定其稳态和动态性能。规定了试验装置和程序、测量和结果展示的要求。没有设定性能限制。测量精度分为三类（A、B和B），在附录A中进行了解释。关于使用实际单位表示结果的指南在附录B中给出。

Specifies methods for testing valves which are used in a circuit in order to determine their steady-state and dynamic performance. Requirements for test installations and procedures, measurements and presentation of results are specified. Does not establish limits of performance. Accuracy of measurement is divided into three classes (A, B and B) which are explained in annex A. Guidance as to the use of practical units for the presentation of results is given in annex B.
