Pneumatic fluid power — Directional control valves — Measurement of shifting time

Transmissions pneumatiques — Distributeurs de commande directionnels — Mesure du temps de commutation

This edition has been replaced by ISO 12238:2023.

Abstract / 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.
