Pneumatic fluid power — Directional control valves — Measurement of shifting time ISO 12238:2001

Publication date:   Jul 26, 2001

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.
