适用范围：This part of ISO 19973 provides test procedures for determining the reliability of pneumatic directional controlvalves by testing and the methods of reporting the results of testing. General test conditions and thecalculation method are provided in part 1 of ISO 19973. The methods specified in that part of ISO 19973 applyto the first failure without repairs, but exclude outliers.The lifetime of pneumatic and electro-pneumatic directional control valves is usually given as a number ofcycles. Therefore, whenever the term “time” is used in this part of ISO 19973, this variable is be understood ascycles.This part of ISO 19973 also specifies test equipment and threshold levels for tests to determine the reliability of pneumatic directional control valves.
