BS ISO 6358-2:2019

This standard BS ISO 6358-2:2019 Pneumatic fluid power. Determination of flow-rate characteristics of components using compressible fluids is classified in these ICS categories:

• 23.100.01 Fluid power systems in general

This document specifies a discharge test and a charge test as alternative methods for testing pneumatic fluid power components that use compressible fluids, i.e. gases, and that have internal flow passages that can be either fixed or variable in size to determine their flow-rate characteristics. However, this document 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), or components that have a cracking pressure such as non-return (check) valves and quick-exhaust valves. In addition, it does not apply to components that exchange energy with the fluid during flow-rate measurement, e.g. cylinders, accumulators.

Table 1 provides a summary of which parts of the ISO 6358 series can be applied to various components.

The charge test cannot be performed on components that do not have downstream port connections.

This document specifies requirements for the test installation, the test procedure, and the presentation of results.
