Full title and description

St IEC TS 60601-4-2:2024 — Medical electrical equipment — Part 4-2: Guidance and interpretation — Electromagnetic immunity: performance of medical electrical equipment and medical electrical systems. This Technical Specification provides guidance for assessing and interpreting the performance of medical electrical equipment (ME equipment) and medical electrical systems (ME systems) when exposed to electromagnetic (EM) disturbances.

Abstract

IEC TS 60601-4-2:2024 offers practical guidance and interpretation to support the application of EMC (electromagnetic compatibility) immunity requirements for medical electrical equipment and systems. It complements normative EMC requirements in the IEC 60601 family by focusing on performance assessment (how devices perform under EM disturbances), appropriate test conditions, observation and acceptance criteria, and specific clarifications (for example cable-length exclusions and references to relevant EMI test methods).

General information

• Publication date: 20 March 2024.
• Publisher: International Electrotechnical Commission (IEC).
• ICS / categories: 11.040.01 (Health care technology); 33.100.20 (Immunity / Electromagnetic compatibility).

Scope

This Technical Specification applies to the performance of ME equipment and ME systems in the presence of electromagnetic disturbances. Its objective is to provide guidance for assessing device performance (rather than only pass/fail safety criteria) under a range of immunity tests and real‑world EM conditions. The document updates and replaces the earlier IEC TR 60601-4-2:2016 and aligns its guidance with related IEC 60601 series EMC requirements.

Key topics and requirements

• Guidance on evaluating ME equipment and ME system performance under electromagnetic disturbances (observation and performance criteria A/B/C).
• Interpretation of immunity test conditions and selection of operating modes most likely to reveal performance degradation.
• Updated test-related parameters (for example changes to conducted disturbance cable-length exclusion from 3 m to 1 m and references to IEC 61000-4-6 where applicable).
• Alignment and cross-reference with IEC 60601-1-2 (EMC for medical electrical equipment) and its amendments.
• Recommended acceptance/observation criteria and documentation practices (emphasis on instructions for use and performance reporting rather than solely on basic safety).
• Clarifications on immunity test levels, applicable phenomena (ESD, radiated RF, EFT/Burst, conducted RF, power-frequency magnetic fields, DIPS) and how to interpret results in the context of clinical use and risk.

Typical use and users

Used by medical device manufacturers, EMC/test engineers, conformity assessment bodies, notified bodies and regulators, hospital biomedical engineering teams, and independent EMC test laboratories. The TS is intended to guide design verification, pre‑market testing strategy, clinical risk assessment related to EMC, and to inform labeling and instructions for safe operation in electromagnetically adverse environments.
