ISO 11197:2019

Overview

ISO 11197:2019 - Medical supply units is a particular ISO standard that specifies basic safety and essential performance requirements for medical supply units (also referred to as ME equipment). It covers surface-mounted or recessed containment systems, cabinetry and enclosures that incorporate patient‑care services and can be either factory‑manufactured or assembled on site. The 2019 fourth edition is based on IEC 60601-1:2005+A1:2012 and amends that general medical electrical equipment standard for the specific context of medical supply units.

Key topics and technical requirements

ISO 11197:2019 addresses technical and safety aspects including:

• Scope and manufacturer responsibility - parties assembling components on site are considered the manufacturer of the medical supply unit.
• General requirements and testing - requirements for verifying basic safety and essential performance of ME equipment.
• Classification, identification and documentation - marking, labelling and required technical documents.
• Electrical safety - protection against electrical hazards for medical electrical equipment integrated into supply units.
• Mechanical safety - protection against mechanical hazards; includes construction, internal cabling methods and tests such as impact resistance.
• Radiation, temperature and other hazards - prevention of unwanted/excessive radiation and excessive temperatures.
• Controls, accuracy and hazardous outputs - requirements for accurate controls and safe outputs.
• Hazardous situations and single-fault conditions - risk considerations and fault‑condition handling.
• Programmable electrical medical systems (PEMS) and electromagnetic compatibility (EMC) considerations for integrated devices.
• Informative annexes: rationale, production testing, documentation and terminology.

Notable editorial and technical changes in the 2019 edition include revised requirements for USB outlets and added methods/tests for internal cabling and impact resistance.

Practical applications and users

ISO 11197:2019 is intended for:

• Designers and manufacturers of medical supply units, cabinetry and enclosures
• On‑site assemblers and installers (who assume manufacturer responsibilities)
• Healthcare facility planners, architects and contractors specifying medical locations
• Maintenance, inspection and testing personnel
• Regulatory, compliance and risk‑management professionals

Typical applications:

• Specification, design and production of wall‑mounted or recessed medical supply units
• Integration of medical gas outlets, electrical sockets, data/USB outlets, lighting and plume extraction
• Site assembly and verification of assembled enclosures to meet medical electrical safety and performance requirements

Related standards (selection)

ISO 11197:2019 references and works with several standards, including:
