Overview
ISO 15883-6:2026 specifies the requirements and test methods for washer-disinfectors (WD) employing thermal disinfection for non-critical medical devices and healthcare equipment. Developed by the International Organization for Standardization (ISO), this standard applies to washer-disinfectors used where adequate disinfection can be achieved through cleaning and thermal processes, with an A₀ value of not less than 60. The focus is on devices and equipment that do not penetrate the skin or contact mucosal surfaces, including items such as wheelchairs, trolleys, bed frames, washbowls, and similar healthcare apparatus. ISO 15883-6:2026 is intended to be used together with ISO 15883-1, which sets out the general requirements for washer-disinfectors.
Key Topics
- Scope and Limitations:
- Applies to non-invasive, non-critical medical devices and healthcare equipment.
- Excludes powered, lumened, semi-critical, and critical medical devices, as well as devices within the scopes of ISO 15883-2, -3, -4, and -7.
- Thermal Disinfection Requirements:
- Specifies cleaning and disinfection processes using hot water, steam, or a combination.
- Requires an A₀ value of not less than 60 for adequate thermal disinfection.
- System Controls and Safety:
- Washer-disinfectors must permit pre-setting of washing and disinfection temperatures and times.
- Requirements for process chemical dosing accuracy and user indication for insufficient chemicals.
- Ensures process verification as per ISO 15883-1.
- Testing and Validation:
- Mandates tests for cleaning efficacy, soil removal, and thermal profile adherence.
- Outlines requirements for thermometric testing using representative full loads.
- Water Quality:
- Specifies the need for water quality suitable for the intended application, referencing ISO/TS 5111 for guidance.
Applications
ISO 15883-6:2026 is vital for healthcare facilities, manufacturers, and service providers that clean and thermally disinfect reusable non-critical medical devices and healthcare equipment. Typical applications include:
- Hospitals and Clinics:
- Cleaning and disinfecting wheelchairs, transport carts, bed frames, and washing accessories.
- Laboratories and Dental Practices:
- Processing non-critical items like glassware, bowls, and cleaning utensils.
- Long-Term Care Facilities:
- Maintaining hygiene standards for reusable aids and equipment that contact intact skin.
Implementing this standard supports infection prevention and control programs, reduces the risk of cross-contamination, and helps ensure compliance with global best practices in medical device reprocessing.
