Six coverage areas in this corpus
US-market standards for industrial control panels and machinery electrical design. NEC is legally enforced; UL 508A covers panel listing.
Electrical equipment of machines for CE-marked and global machinery. Equivalent scope to NFPA 79 for international markets.
Risk assessment and safety function design. PL (Performance Level) path via ISO 13849-1; SIL path via IEC 62061 or IEC 61511 for process.
PLC programming languages and safety software lifecycle (IEC 61131-3). Industrial cybersecurity series (IEC 62443) for networked control systems.
Side-by-side comparison tables mapping clause equivalencies between US and international standards.
Cross-cutting reference models: machine architecture layers, universal safety architecture, and semiconductor compliance stack.

Featured Scenarios
Start here — five common engineering situations
Start with: UL 508A + NEC Article 409 + NFPA 79
Panel intended for US market, UL listing required. All three standards apply — NEC is the legal baseline, UL 508A governs construction and listing, NFPA 79 applies when machine context exists.
Full scenario →Start with: NFPA 79 (US) + IEC 60204-1 (EU) + ISO 12100
Machine sold in both US and EU markets. Design to most restrictive from each. CE marking requires ISO 12100 risk assessment as foundation.
Full scenario →Start with: IEC 61511 + IEC 61508 (foundation)
SIS / ESD system for process industry. IEC 61511 is the application standard; IEC 61508 is the foundation lifecycle standard. CORPUS COMPLETE
Full scenario →Start with: ISO 13849-1 or IEC 62061 + IEC 62443
Safety PLC with network connectivity. Safety function design per PL or SIL path; cybersecurity overlay per IEC 62443. TO VERIFY
Full scenario →Start with: 15-Standard Minimum Compliance Stack
Complex compliance stack for semiconductor fab equipment. SEMI S2/S8/S14 are now in the local corpus alongside the industry overlay.
