SIST EN ISO 22569:2020 PDF

Overview

EN ISO 22569:2020 - Dentistry: Multifunction handpieces (ISO 22569:2020) specifies requirements, test methods, instructions for use and marking for multifunction dental handpieces (commonly called “syringes”) intended for use in the oral cavity. Prepared by ISO/TC 106 in collaboration with CEN/TC 55, this harmonized European and international standard covers classification, performance, safety and reprocessing considerations for these dental devices. It does not apply to dental handpieces and motors, intraoral cameras, polymerisation lamps, powered scalers, powder-jet or prophy handpieces, suction cannulas or saliva ejectors.

Key topics and requirements

The standard addresses technical and safety topics relevant to manufacturers, test labs and regulatory reviewers:

• Scope & classification: shape, number of functions, single‑use vs reusable cannula
• General requirements: materials, mechanical strength and surface properties
• Handling: rotation and pull-off force of cannula, usability and operating controls
• Fluid and air systems: air and water supply, water/air outlets, spray outlet, tightness and pressure requirements
• Temperature control: water, air and spray temperature limits and housing temperature rise
• Backflow prevention: provisions to reduce cross-contamination risk
• Reprocessing: instructions for use, resistance to cleaning/sterilization and verification after reprocessing
• Testing & measurement: sampling, visual inspection, spray angle, pressure and tightness tests, and reporting
• Marking, labelling and packaging: required information for safe operation and traceability

Practical applications and users

EN ISO 22569:2020 is primarily used by:

• Dental device manufacturers designing and certifying multifunction handpieces
• Test laboratories performing conformity, performance and safety testing
• Regulatory and conformity assessment bodies verifying compliance with CEN/ISO requirements
• Dental clinics and procurement teams specifying equipment that meets harmonized safety and reprocessing criteria
• Sterilization service providers ensuring reprocessing instructions are adequate and validated

Benefits include improved device safety, consistent test procedures, clearer labelling and reduced infection risk through standardized backflow prevention and reprocessing requirements.

Related standards (context)

EN ISO 22569:2020 complements other dentistry and medical device standards developed by ISO/TC 106 and national CEN members - notably standards addressing dental handpieces, sterilization processes and medical device labelling and instructions for use. For regulatory alignment, refer to applicable regional medical device regulations and harmonized standards lists.
