ISO 15883-3:2024

Overview - ISO 15883-3:2024 (Washer‑disinfectors for human waste containers)

ISO 15883-3:2024 specifies performance requirements and tests for washer‑disinfectors (WD) that perform emptying, flushing, washing and thermal disinfection of non‑critical human waste containers in a single operating cycle. This second edition updates and replaces ISO 15883-3:2006 and is intended to be read with the general requirements of ISO 15883-1:2024 and the cleaning performance guidance of ISO 15883-5:2021 (with specified exceptions). The standard covers design, control, testing and information requirements to ensure safe, effective processing of items such as bedpans, portable sanitary pans, urine collection containers and similar devices.

Key topics and technical requirements

• Scope and definitions: Clarifies what constitutes non‑critical devices and human waste containers processed by WDs.
• Performance requirements: Criteria for one‑cycle emptying, flushing, cleaning, thermal disinfection, drying and cooling of loads.
• Emptying: Specifies that manufacturers must indicate whether emptying is automatic or manual; automatic emptying must prevent spillage and aerosol generation (tested under clause 6.5.1); manual emptying should be avoided where possible.
• Chemical dosing: Provision for dosing systems when requested; dosing volume must be adjustable with an accuracy of ±10% and faults must be indicated or visually verifiable.
• Instrumentation, controls and process: Requirements for measurement, control and process reproducibility to ensure the disinfection temperature profile is achieved on load surfaces.
• Testing for conformity: Includes tests for drain seal integrity, flushing of absorbent and non‑absorbent materials (toilet tissue specified in Annex B), soil removal, loading/emptying performance and other conformity checks.
• Operational safeguards: Guidance on venting, draining, water quality and requirements to limit contamination and aerosols. Safety conformity references include IEC 61010‑2‑040.

Applications and who uses this standard

• Healthcare procurement and central sterile departments (CSSD) evaluating or acquiring washer‑disinfectors for bedpan and waste container processing.
• Manufacturers and designers of WDs needing to demonstrate performance and regulatory compliance.
• Test laboratories and conformity assessors executing the specified tests (soil removal, flushing, emptying).
• Facilities in hospitals, long‑term care, veterinary, laboratory, dental and pharmaceutical settings where reusable waste containers are processed.
• Maintenance and infection prevention teams implementing safe operation and validation protocols.
