Scope

This part of GB/T 14513 specifies a deflation test and an inflation test as alternative testing methods for determining the flow characteristics of components using compressible fluids.
This part specifies the requirements for testing equipment, testing procedures, and the presentation of test results.
This part applies to pneumatic components with fixed or variable internal flow channels.
This part does not apply to components with unstable flow characteristics during use, such as components exhibiting obvious hysteresis behavior (because they contain elastic parts that deform during flow) or components with internal feedback (such as pressure relief valves) or components requiring opening pressure (such as one-way valves and quick exhaust valves). In addition, this part does not apply to components that exchange energy with the fluid during flow measurement (such as cylinders, accumulators, etc.). The application of GB/T 14513 testing methods to various components is shown in Table 1.
