标准摘要
[中文适用范围]： ISO 6358 的这一部分规定了一种稳态方法，用于测试使用可压缩流体（即气体）的气动流体动力组件，并具有尺寸固定或可变的内部流路，以确定其流量特性。 然而，ISO 6358的这一部分不适用于在使用过程中流量系数不稳定的组件，即表现出显着滞后行为的组件（因为它们可能包含在流动下变形的柔性部件）或具有内部反馈现象的组件（例如监管机构）。 此外，它不适用于在流量测量期间与流体交换能量的部件，例如气缸、蓄能器等。 [外文原描述]： ISO 6358-1:2013 specifies a steady-state method for testing pneumatic fluid power components that use compressible fluids, i.e. gases, and that have internal flow paths that can be either fixed or variable in size, to determine their flow-rate characteristics. ISO 6358-1:2013 does not apply to components whose flow coefficient is unstable during use, i.e. components that exhibit remarkable hysteretic behaviour (because they can contain flexible parts that deform under the flow) or that have an internal feedback phenomenon (such as regulators). In addition, it does not apply to components that exchange energy with the fluid during flow-rate measurement, e.g. cylinders, accumulators, etc. ISO 6358-1:2013 specifies requirements for the test installation, the test procedure, and the presentation of results for the steady-state method.
