Long proof test intervals for SIL overspeed detection systems

Proof testing is a routine action that helps ensure the integrity (SIL level) of a safety instrumented system (SIS) throughout its lifecycle. Long proof test intervals are preferable to short proof test intervals because they reduce unnecessary downtime, especially if the proof testing can be aligned with a machine’s periodic maintenance procedures.   Proof test […]

Maintenance and proof test requirements for SIL overspeed detection systems

Because the integrity of a safety-related system degrades over time, periodic testing (known as proof testing) is essential in order to detect hidden failures. So it is of crucial importance that all safety instrumented systems (SISs) have a maintenance plan in place to support their ongoing operation. This compensates for the safety system integrity degrading […]
