SIST EN ISO 15883-6:2026 PDF

Overview

SIST EN ISO 15883-6:2026 is an international standard developed by CEN in collaboration with ISO, focusing on washer-disinfectors employing thermal disinfection for non-critical medical devices and health care equipment. This part of the ISO 15883 series sets out the specific requirements and testing protocols for washer-disinfectors (WD) where assurance of disinfection can be achieved via cleaning and thermal disinfection-without the need for an independent automated process record. The scope is limited to non-invasive, non-critical devices and equipment, meaning items that do not penetrate skin or come into contact with mucosal surfaces.

This standard is to be used alongside ISO 15883-1, which covers general requirements for washer-disinfectors. SIST EN ISO 15883-6:2026 does not apply to powered, lumened, semi-critical, or critical medical devices, or to items covered under other parts of ISO 15883, such as surgical instruments, endoscopes, or waste containers.

Key Topics

• Scope and Field of Application

  • Applies to washer-disinfectors for non-critical, non-invasive medical devices and health care equipment.
  • Devices processed include items such as laryngoscope handles, washbowls, cleaning equipment (buckets), patient transport carts, bed frames, and wheelchairs.
  • Excludes powered devices, devices with lumens, and semi-critical or critical items.

• Thermal Disinfection Requirements

  • Specifies that disinfection must be accomplished through a combination of cleaning and thermal methods-such as hot water rinsing or steam-with a required A0 value of not less than 60.
  • Detailed requirements on temperature and time profiles for both cleaning and disinfection cycles, with systematic verification for efficacy.

• Mechanical and Control Systems

  • Washer-disinfectors must be equipped with systems for controlling and monitoring washing and disinfection temperatures, detergent dosing, and cycle timing.
  • Adjustable settings are required for processes to accommodate varied load types.

• Process Verification and Testing

  • Requires specific conformity testing, including process verification, soil removal, and thermometric tests.
  • Acceptance criteria for cleaning performance are specified with reference to ISO 15883-1 and ISO 15883-5.

• Documentation and User Information

  • Manufacturers must provide clear information on the intended devices, supported loads, cycle times, and temperature data-helping purchasers select appropriate washer-disinfectors for their needs.

Applications

SIST EN ISO 15883-6:2026 has practical applications across a range of health care environments where non-critical items require reliable cleaning and disinfection:

• Hospitals and Clinics

  • Ensures safe processing of general reusable equipment such as bedpans, trays, and mobility aids.

• Dental and Veterinary Practices

  • Allows for compliant reprocessing of non-critical devices and supportive equipment.

• Long-Term Care Facilities

  • Supports infection prevention for reusable aids and support equipment, enhancing patient safety.

• Laboratories and Support Areas

  • Provides guidance for the disinfection of non-invasive tools and carriers, where sterilization is not mandated.

Implementing SIST EN ISO 15883-6:2026 supports compliance with European and international regulations, fits within medical device quality management systems, and meets infection control best practices.

Related Standards

Organizations should consider the following standards in association with SIST EN ISO 15883-6:2026 for comprehensive washer-disinfector compliance and performance:
