Overview
EN ISO 5467-2:2022 - "Dentistry - Mobile dental units and dental patient chairs - Part 2: Air, water, suction and wastewater systems" specifies requirements and test methods for the fluid and suction systems of mobile dental units. It covers connections to facility supplies (compressed air, water, suction, wastewater), internal system materials and design, incoming water and air quality, suction performance, and interfaces to dental handpieces. The standard excludes amalgam separators and mobile units intended for oral surgery that require sterile air/water.
Key topics and technical requirements
- Connections and interfaces
- Requirements for mobile dental unit connections to compressed air, water, suction and wastewater drain plumbing.
- Properties of connections to dental handpieces (air, water, suction, wastewater).
- Water systems
- Materials, design and construction of internal compressed air and procedural water systems.
- Incoming potable water quality and provisions for bottled water supplies used for procedural water.
- Backflow prevention when connected to external drinking water supply.
- Cuspidor, water venturi, particle and bacterial filter provisions; water sampling connection point; wastewater container and drain connections.
- Requirements for biofilm control and retraction prevention.
- Air systems
- Classification and purity class of dental air, including requirements for integrated compressed air source equipment.
- Particle and bacterial filters, condensate drain, compressed air filtration and acceptable sound levels.
- Suction systems
- Suction source connection, maximum suction pressure, suction pressure head loss, suction flow rate, solids filters and air separators.
- Cannula connector configuration and hose requirements.
- Testing, documentation and labelling
- Test methods such as particle filter testing, suction flow rate testing, visual inspection, sampling and reporting.
- Requirements for instructions for use, technical description and test reports.
Practical applications
- Ensures safe, reliable fluid and suction performance of mobile dental units used in clinics, outreach programs, mobile clinics and temporary treatment sites.
- Guides design and manufacture of mobile dental units and dental patient chairs to meet EU/CEN and ISO expectations for air, water, suction and wastewater systems.
- Supports service technicians and maintenance teams with test methods for filters, suction flow rates and system inspection.
- Helps infection control teams assess incoming water/air quality, filtration and biofilm control measures.
Who should use this standard
- Dental equipment manufacturers and designers
- Regulatory bodies and conformity assessment organizations
- Dental clinics and mobile clinic operators
- Service/maintenance technicians and biomedical engineers
- Procurement and quality managers specifying mobile dental units
