Global Machine — US + EU Markets
Project Summary
| Field | Detail |
|---|---|
| Markets | United States + European Union |
| Application | Industrial machine sold in both US and EU |
| US requirement | NFPA 79 + NEC + UL 508A (if panel listing required) |
| EU requirement | CE marking — Machinery Directive compliance |
Starting Standards
| Standard | Market | Status |
|---|---|---|
| NFPA 79 2024 | US | Complete in corpus |
| IEC 60204-1 2018 | EU / International | Complete in corpus |
| ISO 12100 2010 | EU (CE marking foundation) | Planned TO VERIFY |
| ISO 13849-1 2023 | Both (if safety functions) | Planned TO VERIFY |
Design Strategy
Design to the most restrictive requirement from each standard.
Key principle: Both standards cover the same technical topics (electrical equipment of machines) but differ in some requirements. For each topic, identify which standard is more restrictive and design to that level.
For each topic area:
1. Check NFPA 79 requirement
2. Check IEC 60204-1 requirement
3. Apply the more restrictive of the two
4. Document compliance to both
Critical Differences
| Aspect | US (NFPA 79) | EU (IEC 60204-1) | Resolution |
|---|---|---|---|
| PE wire color | Green or bare | Yellow-green required | Use yellow-green |
| Voltage scope | 600 V max | 1000 V AC / 1500 V DC | IEC 60204-1 covers higher voltages |
| Documentation requirements | Chapter 19 | Clause 17 (more prescriptive) | Follow IEC 60204-1 Clause 17 |
| Neutral conductor | Less explicit | More explicit treatment | Follow IEC 60204-1 |
CE Marking Foundation
CE marking under the Machinery Directive (2006/42/EC) requires:
- ISO 12100 risk assessment (first, always) TO VERIFY
- IEC 60204-1 for electrical equipment requirements
- ISO 13849-1 or IEC 62061 if safety functions exist TO VERIFY
- Technical file and Declaration of Conformity
Repository Paths
| Standard | Repository Path |
|---|---|
| NFPA 79 | rag/us/nfpa79/ |
| IEC 60204-1 | rag/international/machinery/iec_60204_1/ |
| ISO 12100 | rag/international/functional_safety/iso_12100/ [planned] |
| Crosswalk | rag/crosswalks/overlap_matrix/nfpa79_iec60204_overlap.md |
Recommended Next Steps
- NFPA 79 ↔ IEC 60204-1 crosswalk — see the differences
- ISO 12100 — risk assessment foundation
- ISO 13849-1 — if safety functions exist
