IEC 60204-1 and International Machinery Standards
Standards for electrical equipment of machines intended for CE marking or global markets.
Standards in This Family
| Standard | Edition | Scope | Status |
|---|---|---|---|
| IEC 60204-1 | 2016+AMD1:2021 | Electrical equipment of machines | Review pending |
| ISO 12100 | 2010 | Risk assessment foundation | See Functional Safety |
| ISO 13849-1 | 2023 | Safety-related control systems (PL) | See Functional Safety |
| IEC 62061 | 2021 | Safety-related control systems (SIL) | See Functional Safety |
CE Marking Foundation
For EU/CE-marked machinery, the minimum starting set is:
- ISO 12100 — Risk assessment (required as foundation)
- IEC 60204-1 — Electrical equipment requirements
- ISO 13849-1 or IEC 62061 — If safety functions are present
Machinery Directive (2006/42/EC) requires this foundation. ISO 12100 is harmonized under the directive as a Type A standard.
IEC 60204-1 vs NFPA 79
IEC 60204-1 and NFPA 79 are broadly equivalent in technical scope but differ in structure and some requirements:
| Aspect | IEC 60204-1 | NFPA 79 |
|---|---|---|
| Market | Global / EU | United States |
| Voltage reference | 1000 V AC / 1500 V DC | 600 V |
| Neutral conductor | Explicit N treatment | Less explicit |
| Documentation | Clause 17 (detailed) | Chapter 19 |
| Colors | Yellow-green PE required | Green or bare allowed |

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.
