Overview
ISO 22569:2020 - "Dentistry - Multifunction handpieces" specifies requirements, test methods, instructions for use and marking for multifunction dental handpieces (commonly called "syringes") intended for use in the oral cavity. The standard defines how these devices should perform and be tested, and sets out documentation and labeling expectations. It explicitly excludes dental handpieces and motors, intraoral cameras, polymerisation lamps, powered scalers, powder-jet and prophy handpieces, suction cannulas and saliva ejectors.
Key topics and technical requirements
ISO 22569:2020 covers the following technical areas and test methods (by clause):
- Classification (shape, number of functions, single‑use vs reusable cannula)
- General requirements and handling (including rotation and pull‑off force of cannula)
- Materials and mechanical strength, surface requirements and housing integrity
- Air, water and spray supply: requirements for outlets, tightness, pressure and spray performance (spray angle tests are specified)
- Temperature: water, air and spray temperatures and temperature rise of the housing
- Backflow prevention to protect patient safety
- Reprocessing and resistance to reprocessing (cleaning, disinfection/sterilization compatibility)
- Operating controls and usability, connection and supply interfaces
- Marking, labelling, packaging and instructions for use, plus a template for test reports and sampling/testing procedures
- Measurement and test methods (visual inspection, handling tests, equipment and procedural test descriptions are provided in Clause 7)
Note: ISO 22569:2020 provides requirements and methods but does not list numerical performance limits in this summary - consult the full document for exact test criteria.
Practical applications and who uses this standard
ISO 22569:2020 is used by:
- Dental device manufacturers for design, validation and production control of multifunction handpieces
- Product development and R&D teams to ensure compliance during prototyping and performance testing
- Quality assurance and regulatory affairs for conformity assessment, technical documentation and CE/market submissions
- Test laboratories executing the standardized test methods and issuing test reports
- Procurement and clinical engineering teams specifying equipment for dental clinics and hospitals
- Dental clinics and infection‑control professionals to understand reprocessing and safety expectations
This standard helps ensure safety, reliability and interoperability of dental multifunction handpieces and supports regulatory compliance and informed procurement decisions.
