ISO 15883-3:2006

Overview - ISO 15883-3:2006 (Washer-disinfectors for human waste containers)

ISO 15883-3:2006 specifies performance, safety and test requirements for washer-disinfectors that empty, flush, clean and thermally disinfect human waste containers in a single operating cycle. Intended to be used together with ISO 15883-1 (general requirements), this part covers reusable vessels such as portable sanitary pans, urine bottles, suction bottles, hospital bowls and supports for single‑use bedpans. The standard aims to reduce spillage, aerosol generation and infection risk during processing of waste containers in healthcare and related settings.

Key topics and technical requirements

• Scope & application: Applies to washer-disinfectors designed for emptying, flushing, cleaning and thermal disinfection of reusable human waste containers; used alongside ISO 15883-1.
• Thermal disinfection metric (A0): Thermal disinfection is achieved when surfaces receive an A0 value of at least 60, using the time–temperature relationship defined in ISO 15883‑1 test methods.
• Temperature control: Surface temperatures of loads and chamber walls must be within 0 °C to 15 °C of the specified disinfection temperature during the required exposure time.
• Emptying: Manufacturer must specify manual or automatic emptying. Automatic systems must prevent spillage and aerosol release (testable per clause 6.5).
• Cleaning stages: Includes flushing to remove gross soiling and washing of inner and outer surfaces; cleaning efficacy is validated by tests in clause 6.6.
• Chemical dosing (optional): Provision for descalant, detergent and/or rinse aid; dosing accuracy must be ±10% or better and faults must be indicated or visually verifiable.
• Controls & instrumentation: Machines must provide chamber temperature display or indicator and permit installation of a temperature recorder when required.
• Rinsing & drying: Rinsing may occur before or during disinfection; a separate drying stage is optional.
• Conformity tests: Detailed tests for drain seal integrity, flushing of absorbent/non‑absorbent materials (e.g., toilet tissue), loading/emptying performance and soil removal are specified.

Applications - who uses ISO 15883-3

• Manufacturers and designers of bedpan washer‑disinfectors
• Hospital procurement and biomedical engineering teams specifying safe processing equipment
• Infection prevention and control professionals ensuring validated reprocessing of waste containers
• Test laboratories and conformity assessors performing validation and acceptance testing
• Regulators and standards committees evaluating device performance and safety

Related standards
