SIL-rated safety systems require care across their entire lifecycle. We explain how proof testing and management keep integrity intact for decades.
A safety instrumented system is only as good as its ongoing management. Integrity that is verified at handover must be maintained through proof testing, change control and competency for the life of the asset.
Proof testing that proves integrity
Scheduled proof testing validates that safety functions will perform on demand. Documented, disciplined testing is the backbone of a credible safety case.
- Lifecycle management to IEC 61511
- Scheduled proof testing and records
- Rigorous management of change
- Competency assurance for maintenance teams
