本标准规定了使用液体作为试验流体，用于连续工作的电磁阀额定流量和压力特性的试验方法，包括用于比较阀门容量的阀门流量系数（Cv/Kv）。本标准不适用于液压流体动力阀，NFPA和ISO/TC 131制定的标准中介绍了液压流体动力阀的不同试验方法和额定值，这些方法在整个流体动力行业中得到了认可和使用。

This standard specifies methods of testing for rating flow and pressure characteristics of solenoid valves intended for continuous duty service using liquid as a test fluid, including the valve flow coefficient (Cv/Kv) for comparison of valve capacity.This standard is not applicable to hydraulic fluid power valves, for which different methods of test and rating, presented in standards developed by NFPA and ISO/TC 131, are accepted and used throughout the fluid power industry.
