Frequent Functional Testing vs Equipment Wear
Apply risk-based proof test intervals and automated diagnostics to sustain required SIL confidence while minimising wear-inducing full-stroke test cycles.

Business Context
Routine functional testing demonstrates that Safety Instrumented
Functions remain capable of performing their intended protective
actions. Repeated testing, however, subjects sensors, actuators, valves,
and mechanical components to additional operating cycles that contribute
to wear.
The Contradiction
More functional testing increases confidence in system performance.
More testing accelerates equipment wear.
Why It Exists
Testing is essential to reveal hidden failures, yet every test
introduces mechanical movement, operational effort, and maintenance
activities that gradually affect equipment condition.
Direction
Optimize testing strategies through automated diagnostics, partial proof
testing, condition-based maintenance, and risk-based proof test
intervals that maintain confidence while reducing unnecessary equipment
stress.
