1适用范围和领域注:本方法将作为ISO 6358的替代方法，ISO 6358被公认为首选流量额定试验程序和报告方法。1.1定义额定参数、试验方法和报告固定孔板气动流体动力部件流量的方法。1.2通过为部件制造商和用户提供易于理解的标准方法，开发、验证和传达气动流量额定值，促进更好的气动流体动力系统。本标准不适用于流体控制协会标准ANSI/FCI 68-1和ANSI/FCI 68-2中定义的用于工艺流体流量控制的控制阀。

1 Scope and field of applicationNOTE This method is to be used as an alternative to ISO 6358, which is recognized as the preferred flow rating test procedure and reporting method.1.1 To define a rating parameter, test method, and method of reporting flow in fixed orifice pneumatic fluid power components.1.2 To promote better pneumatic fluid power systems by providing manufacturers and users of components with an easily understood standard means of developing, verifying and communicating pneumatic flow ratings.This standard does not apply to control valves used in flow control of process fluids, as defined in Fluid Control Institute standards ANSI/FCI 68-1 and ANSI/FCI 68-2.
