Methods to assess the reliability of pneumatic components—Part 5: Non-return valves, shuttle valves, dual pressure valves (AND function), one-way adjustable flow control valves, quick-exhaust valves (English Version)

Scope: This document specifies the test equipment, test conditions, test procedures and reliability thresholds for evaluating the reliability of check valves, pilot-operated check valves, shuttle valves, dual pressure valves (AND valves), one-way throttle valves and quick discharge valves. and treatment of test results. This document applies to the first failure of pneumatic components of the above types without maintenance, with the exception of some outliers.
