Emergency Stop (Clause 9)
IEC 60204-1 Clause 9 addresses emergency stop (Category 0, 1, 2) and safety-related stop functions. For formal safety function design, this clause works with:
- ISO 13849-1 — Performance Level (PL) approach
- IEC 62061 — SIL approach for machinery
- ISO 13850 — Emergency stop devices (referenced by both)
Global Machine Projects
For machines sold in both US and EU markets, use both IEC 60204-1 and NFPA 79 and design to the most restrictive requirement from each.
Key differences to watch for:
- Wire colors: IEC 60204-1 requires yellow-green for PE; NFPA 79 allows green or bare
- Voltage rating: IEC 60204-1 covers to 1000 V AC; NFPA 79 is 600 V
- Neutral conductor requirements differ in detail
