Fuller Technologies Achieves SIL Subsystem Certification for Gas Analysis Systems — IEC 61511
Risknowlogy has independently certified safety-related gas analysis subsystems supplied by Fuller Technologies Denmark A/S in accordance with IEC 61511 — confirming verified SIL compliance for use in safety instrumented functions across the process industry.
What Was Certified
The certification covers gas analysis systems used in safety instrumented functions (SIFs), where reliable detection and timely response are essential to risk reduction in the process industry.
This independent assessment confirms that the assessed subsystems meet the applicable functional safety requirements and that the associated safety claims are technically justified, documented, and verified.
Scope of certification: Functional safety management, safety requirements specification, hardware and reliability requirements, software requirements, basic safety principles, user documentation, Factory Acceptance Testing (FAT), and Integrated Factory Acceptance Testing (IFAT).
Verified Safety Performance
As part of the certification process, the safety functions implemented by the subsystem were reviewed and verified, including:
- Safety function definition and architecture
- Hardware fault tolerance (HFT)
- Proof test intervals (PTI)
- Average probability of failure on demand (PFDavg)
- SIL capability of the implemented functions
The resulting safety parameters demonstrate compliance with the targeted SIL levels and provide operators with the data required for integration into their Safety Instrumented Systems.
What This Means for Operators and Stakeholders
For operators, a certified subsystem provides confidence that safety functions are based on validated assumptions and proven reliability data. For engineering contractors and system integrators, it reduces uncertainty during SIL verification and safety lifecycle activities. For insurers, auditors, and regulators, it offers independent evidence that functional safety requirements have been systematically addressed.
