IEC 61511:2016 — Functional safety: Safety instrumented systems for the process industry sector
IEC 61511:2016 — Functional safety: Safety instrumented systems for the process industry sector — 45% of in-scope requirements covered.
5 requirements · 5 in scope (4 designed · 1 advisory). The 45% is weighted over the in-scope base.
Source: IEC 61511:2016 Parts 1-3 — the process-sector application of IEC 61508 defining safety instrumented systems (SIS), the safety lifecycle for process plant, and proof-test / management requirements. KYE™ governs the authority, evidence and finality of an AI-recommended physical-safety action (turbine trip, unit shutdown, derate) against a SIL-validated model-authority claim and the §25 safety floor. Starter requirement set (Wave-Ralph-Industrial); deepen by graft. · License: IEC — standard text is copyrighted; KYE™ registry paraphrases each requirement's intent and cites the official clause identifier for mapping purposes only.
