Side-by-side standard comparisons: NFPA 79 ↔ IEC 60204-1, IEC 61511 ↔ IEC 61508, IEC 60079 ↔ NEC 500/505, and more.

Software Stack

Site technology stack, Jekyll configuration, and deployment notes.

RAG File Browser

Browse all canonical RAG source files directly — standards, training modules, design frameworks, and commissioning checklists.

These reference models are derived from the canonical reference library at control-standards/rag/. They are design aids, not authoritative standards documents. Always verify against the applicable standard and OEM documentation.

Trust Boundary — Engineering Judgment Required

This site is an independent educational reference for industrial automation standards. It paraphrases and organizes guidance in original language; it is not a substitute for the official published standards, professional engineering judgment, or legal review, and content has not been independently verified against current published editions.

Items marked Review pending await technical review against the identified edition. Items marked Planned have no reviewed source material behind them. Do not rely on this site for compliance determinations, safety-critical design decisions, or legal interpretation.
