Overview
ISO 5467-2:2022 - "Dentistry - Mobile dental units and dental patient chairs - Part 2: Air, water, suction and wastewater systems" - defines requirements and test methods for the fluid and air systems of mobile dental units. The standard covers connections to facility supplies, internal materials and construction of compressed air and water systems, incoming water and air quality, suction performance, and interfaces to dental handpieces. It applies to mobile dental units not intended for oral surgery that requires sterile air or water and does not include amalgam separators.
Key topics and technical requirements
ISO 5467-2:2022 focuses on practical safety, performance and testability of mobile dental unit utilities. Major technical topics include:
-
Supply and interface connections
- Requirements for connections to compressed air, potable water, suction supply and wastewater drains
- Configuration and documentation of supply connection points
-
Compressed air systems
- Classification of integrated compressors by lubrication type (oil‑lubricated vs non‑oil‑lubricated)
- Filtration, condensate drainage and compressed air quality consistent with referenced purity classes
-
Water systems and wastewater
- Materials, design and construction of procedural water systems inside the unit
- Incoming water requirements and bottled water options
- Backflow prevention, cuspidor and wastewater container provisions
- Particle and bacterial filter provisions, water sampling points and biofilm treatment considerations
-
Suction systems
- Performance tests for suction flow rate and maximum suction pressure
- Cleansing elements: solids filters, air separators and configuration of cannula connectors and hoses
-
Testing, sampling and documentation
- Visual inspection, particle filter tests, suction flow rate tests and sampling protocols
- Requirements for instructions for use and a technical description; test reports are specified
Practical applications and typical users
ISO 5467-2 is intended for professionals who design, manufacture, test, procure, install or regulate mobile dental units:
- Manufacturers and product designers - to design compliant air, water and suction subsystems and prepare technical documentation and instructions for use.
- Test and certification laboratories - to perform the standardized tests (filter performance, suction flow rates, visual inspections) and produce test reports.
- Dental clinics and mobile service providers - to evaluate unit specifications, ensure safe connection to facility utilities, and implement maintenance and infection‑control practices.
- Regulators and procurement teams - to set procurement criteria and verify compliance with international performance and safety expectations.
