Full title and description

ANSI/AAMI/IEC 60601-2-25:2011/(R)2016 — Medical electrical equipment — Part 2-25: Particular requirements for the basic safety and essential performance of electrocardiographs. This particular standard specifies safety and essential-performance requirements, tests and documentation for electrocardiographs (ECG/ EKG) intended to produce electrocardiogram reports for diagnostic purposes, whether as stand‑alone equipment or as part of a medical electrical (ME) system. It aligns the IEC 60601-2-25:2011 technical content with the U.S. national adoption/reconfirmation.

Abstract

IEC 60601-2-25 (adopted as ANSI/AAMI/IEC 60601-2-25:2011/(R)2016) defines particular requirements that amend and supplement the general IEC 60601-1 requirements for medical electrical equipment. It covers electrical safety, essential performance, measurement definitions and performance criteria for electrocardiographs used to acquire diagnostic‑quality ECGs, plus required markings, documentation and specific test methods. Informative annexes provide definitions/rules for ECG measurement, calibration/test data sets and a CTS test atlas to support conformity assessment.

Scope

The standard applies to the basic safety and essential performance of electrocardiographs intended to produce electrocardiogram (ECG) reports for diagnostic purposes. It covers devices intended as stand‑alone ECG systems or as part of ME systems and addresses use in normal and some uncontrolled environments (e.g., ambulance or air transport) where specifically intended. Exclusions include vectorcardiography loops, certain ambulatory ECG devices covered by IEC 60601-2-47 when not intended for diagnostic reports, and cardiac monitors covered by IEC 60601-2-27 when not intended for diagnostic reports. The standard amends and supplements the general IEC 60601-1 requirements and consolidates earlier related particular standards.

Key topics and requirements

• Essential performance: definition and requirements to ensure ECG output suitable for diagnostic interpretation (signal fidelity, frequency response, noise limits).
• Electrical safety: protection against electric shock, isolation, leakage currents and applied parts design consistent with IEC 60601-1.
• Input characteristics and electrode leads: input impedance, common‑mode rejection, lead‑fail and electrode disconnection behavior.
• Defibrillation and high‑energy events: requirements for protection of patient‑connected circuits and recovery of essential performance after defibrillation pulses.
• EMC / immunity considerations: requirements referencing IEC 60601-1-2 for electromagnetic compatibility to ensure reliable ECG acquisition in real environments.
• Mechanical and environmental requirements: marking of operating conditions and tests for performance in intended environments (temperature, humidity, transport/ambulance use where applicable).
• Identification, markings and documentation: detailed labelling, user instructions, performance specifications and warnings required for safe use.
• Testing and conformity assessment: specified test methods, calibration/test data sets, and informative annexes (Annex FF/GG/HH) to support type testing and clinical test suites.

Typical use and users

Manufacturers and designers of electrocardiographs and ECG subsystems use this standard to design, verify and document device safety and essential performance. Regulatory and compliance engineers, test laboratories, notified bodies/registrars, clinical engineering departments, hospital procurement teams, and R&D teams developing ECG equipment or ME systems that include ECG functionality rely on the standard for product specifications, type testing and conformity assessment.

Related standards

Key related and supporting standards commonly used with IEC 60601-2-25 include: IEC 60601-1 (general requirements for basic safety and essential performance), IEC 60601-1-2 (electromagnetic compatibility), IEC 60601-2-27 (electrocardiographic monitoring equipment), IEC 60601-2-47 (ambulatory ECG systems), IEC 62304 (medical device software life cycle), IEC 62366 (usability), and relevant national variants/adoptions such as ANSI/AAMI/IEC 60601 series US editions. Manufacturers should consider applicable device‑class standards, software/quality system standards (e.g., ISO 13485) and regional regulatory requirements when applying this standard.

FAQ

Q: What is this standard?

A: It is the particular standard (IEC 60601-2-25) that specifies additional safety and essential‑performance requirements for electrocardiographs. The U.S. national version is published/adopted as ANSI/AAMI/IEC 60601-2-25:2011 with a reconfirmation notation (R)2016.

Q: What does it cover?

A: It covers functional performance requirements (signal fidelity, frequency response, noise limits), electrical and mechanical safety protections, electrode/lead performance, defibrillation protection, marking/documentation, and test procedures (with informative annexes for ECG measurement rules and calibration/test data). It supplements IEC 60601-1 general requirements.

Q: Who typically uses it?

A: Device manufacturers, compliance engineers, test labs, notified bodies/registrars, clinical engineers, and procurement/regulatory teams involved with ECG equipment and ME systems that include ECG functionality.

Q: Is it current or superseded?

A: The edition in question is IEC 60601-2-25 Edition 2.0 (2011) and is shown as adopted/reconfirmed for U.S. national use as ANSI/AAMI/IEC 60601-2-25:2011/(R)2016. Users should verify whether any subsequent amendments, newer editions, or additional national deviations/amendments have been published since the reconfirmation; always check the issuing bodies (IEC, AAMI or national standards body) for the absolute latest status before relying on it for compliance.

Q: Is it part of a series?

A: Yes — it is Part 2-25 of the IEC 60601 series (medical electrical equipment). The 60601 family contains the general standard (Part 1) and many particular‑parts (Part 2‑xx) addressing specific device types (for example, 2-27, 2-47) and collateral standards (e.g., 60601-1-2 for EMC).

Q: What are the key keywords?

A: Electrocardiograph, ECG, EKG, medical electrical equipment, essential performance, electrical safety, defibrillation protection, electrode leads, calibration, test data sets, IEC 60601-2-25, AAMI/ANSI adoption.
