SIL Math and Reliability

working the numbers

Articles on the quantitative side of SIL verification: PFDavg, failure rates, proof testing, common cause, spurious trips, and voting architectures. Each one works through the math a FuSa engineer uses to show a safety instrumented function meets its target SIL.

Proof Testing of SIFs: Understanding Its 3 Purposes and Its Importance
Proof testing ensures your Safety Instrumented Functions (SIFs) work when needed by uncovering hidden faults. Learn why proof tests are crucial for lowering PFDavg and maintaining Safety Integrity Level (SIL)…
