The official published standard — required for final decisions

Confirm the governing edition, jurisdiction, and project-specific requirements before applying anything on this page.

Standards Explorer

Industrial Automation Standards

Browse standards by family. Use the decision workflow if you're unsure which standard applies to your project.

Use this when

You need to know which published standard governs a machine, panel, safety function, or network — or what a specific standard actually covers.

Start here

Unsure what applies? Open the Standards Finder. Already know the family? Pick it from the sidebar or the quick-decision map below.

Next step

Record the selection at the Standards Selection lifecycle stage, and use the crosswalks where US and international standards overlap.

Quick Decision

US panel / machinery only?   → NEC + NFPA 79 + UL 508A
International / CE marking?  → IEC 60204-1 + ISO 12100 + ISO 13849-1
Safety functions (PL)?       → ISO 13849-1 + IEC 62061
Safety functions (SIL)?      → IEC 62061 (machinery) or IEC 61511 (process)
Process SIS?                 → IEC 61511 + IEC 61508
Hazardous-area / Ex?         → IEC 60079 + NEC Art. 500/504/505
Semiconductor tool / fab?    → SEMI S2/S8/S14 + IEC 60204-1 + NFPA 79
Global (US + EU)?            → NFPA 79 + IEC 60204-1 + ISO 13849-1 (design to most restrictive)

Applicability note: these are common starting points, not complete determinations. Actual applicability also depends on the authority having jurisdiction, listing requirements, state/local code adoption, hazardous-location classification, customer specifications, product-specific standards, and where the equipment boundary ends and the installation begins. Confirm the governing editions for your project before relying on any row above.

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.
