This International Standard: - specifies test procedures for measuring the shifting times of electrically- or pneumatically-operated directional control valves and moving-part logic elements, - establishes a definition for shifting time, and - is intended to improve the application of pneumatic fluid power by providing users and manufacturers of pneumatic valves with a standardized test procedure for measuring the shifting time it defines.
