IEC 60601
The safety standard family for medical electrical equipment: electrical, mechanical and functional safety for devices that connect to a patient or to mains power.
- Full title
- IEC 60601-1: Medical electrical equipment — Part 1: General requirements for basic safety and essential performance
- Current edition
- IEC 60601-1:2005 + Amendment 1:2012 + Amendment 2:2020, known as “edition 3.2”. A fourth edition is in development
- Applies to
- Medical electrical equipment and systems. It does not cover in vitro diagnostic equipment, which falls under the IEC 61010 series
- Structure
- A general standard (60601-1), collateral standards (60601-1-x) and particular standards for specific device types (60601-2-x and 80601-2-x)
In short
Compliance is shown mostly by type testing at an accredited laboratory, backed by a risk management file. Two ideas run through the standard. Basic safety is freedom from unacceptable risk caused directly by physical hazards. Essential performance is the clinical function whose loss or degradation would create unacceptable risk. Both must hold in normal use and when a single fault occurs.
The family
- 60601-1, the general standard. Protection against electric shock (means of protection, leakage currents, applied parts), mechanical hazards, radiation, excessive temperature and fire, accuracy of controls, construction, and markings and accompanying documents.
- 60601-1-2. Electromagnetic compatibility: emissions and immunity.
- 60601-1-6. Usability, which points to IEC 62366-1.
- 60601-1-8. Alarm systems.
- 60601-1-11 and 60601-1-12. Equipment used in home healthcare and in emergency medical services.
- 60601-2-x particular standards. Requirements for one device type. Where a particular standard exists, it modifies and takes precedence over the general standard.
On a software project
- Clause 14 covers programmable systems. It requires a documented development life cycle, requirements, architecture, verification, validation and change control for programmable electrical medical systems, and points to IEC 62304 for the software.
- Identify essential performance early. It defines what hardware and software must maintain during faults and during EMC testing, and the test laboratory needs a way to observe it, which often means test modes or logging built for the purpose.
- Software often implements the risk controls for hardware hazards. Interlocks, watchdogs, safe states and alarm handling become software requirements traced to hazards in the ISO 14971 file.
- Alarm behaviour is mostly software. Priorities, signals, latching and acknowledgement under 60601-1-8 are design decisions with usability evidence behind them.
- Plan a design freeze before formal testing. Changes after testing, including some software changes, can require a re-test.
Worth knowing
- The standard requires risk management to ISO 14971, and the laboratory reviews the risk file as part of the assessment.
- Countries adopt it with national differences, for example ANSI/AAMI ES60601-1 in the United States, CAN/CSA-C22.2 No. 60601-1 in Canada and EN 60601-1 in the EU. A CB Scheme test report helps reuse one set of results across markets.
- Particular standards are revised on their own schedules, so not all of them are aligned with the latest amendment of the general standard.
