Pneumatic fluid power. Directional control valves. Measurement of shifting time Ingestion-build-201039 3 Classification of assemblies 51 Scope 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.
