SIST EN ISO 80601-2-56:2017 PDF

Overview

SIST EN ISO 80601-2-56:2017 (ISO 80601-2-56:2017) is the international/European standard that specifies the particular requirements for basic safety and essential performance of electrical clinical thermometers used to measure human body temperature. It complements general medical electrical equipment requirements (IEC/EN 60601 series) and applies to clinical thermometers as standalone ME (medical electrical) equipment or as ME systems when connected to secondary indicators, printers or other auxiliary devices. The standard does not cover auxiliary equipment itself or screening thermographs for mass febrile screening (covered by IEC 80601‑2‑59).

Key topics and technical requirements

The standard sets out normative requirements and guidance on topics including:

• Basic safety and essential performance expectations for electrical clinical thermometers measuring patient body temperature.
• Applicability to ME equipment and ME systems (clauses indicate when requirements apply to equipment only or to systems).
• Requirements that reference core IEC/ISO standards such as IEC 60601‑1 (general medical electrical safety), IEC 60601‑1‑2 (EMC), and usability and labeling standards referenced in the foreword and Annex ZA.
• Interface accommodation for secondary indicators, printers and other accessories to form ME systems while excluding the auxiliary equipment from the standard’s direct scope.
• Risk management linkage where applicable (consistent with device directives and IEC/ISO risk processes).
• Requirements for labeling, instructions for use, and information to support safe use and conformity assessment (see relationships to Directive 93/42/EEC as noted in Annex ZA).

Note: the standard explicitly excludes detailed requirements for hazards that arise solely from the intended physiological function of the device, except where referenced in IEC 60601‑1 clauses.

Practical applications - who uses this standard

This standard is essential for:

• Medical device manufacturers designing, validating and documenting electrical clinical thermometers or thermometer systems.
• Regulatory and quality teams preparing technical documentation for CE marking and conformity to EU medical device directives/regulations.
• Product test laboratories and conformity assessment bodies assessing safety, essential performance and EMC for clinical thermometers.
• Clinical engineers and procurement specialists specifying devices that meet recognized safety and performance criteria.
• Design engineers and usability specialists integrating interfaces (displays, printers) and ensuring compliance with the IEC 60601 family requirements.

Related standards and references

• IEC/EN 60601‑1 (medical electrical equipment - general requirements)
• IEC 80601‑2‑59 (screening thermographs - excluded from this standard)
• Referenced guidance listed in Annex ZA (ISO 14155, ISO 15223‑1, ISO 17664, IEC 60601‑1‑2, etc.)

By following ISO 80601‑2‑56:2017, manufacturers and assessors ensure clinical thermometers meet harmonized expectations for safety, essential performance, labeling and system interfaces, and support regulatory compliance and patient safety in clinical temperature measurement.
