ISO 18397:2016

Overview

ISO 18397:2016 - Dentistry: Powered scaler defines requirements and test methods for air-powered and electrical-powered scaler handpieces and scaler tips used on patients. It applies to ultrasonic scalers of piezo, ferrostrictive and magnetostrictive types, whether operated as stand‑alone units or connected to dental units. The standard also covers manufacturers’ instructions, marking, labelling and packaging, and replaces ISO 15606:1999 and ISO 22374:2005.

Key topics and technical requirements

ISO 18397:2016 sets out detailed performance, safety and testing requirements. Major topics include:

• Classification of scaler handpieces and tip types (screw-in vs non-screw).
• Materials and surface requirements for biocompatibility and cleanability.
• Mechanical tests: drop test, vibration, tip breakage resistance, stall effort.
• Scaler tip performance: extraction force, insertion force, holding torque, tightening torque, power output.
• Operational parameters: frequency, amplitude, air and water pressure, cooling liquid supply.
• Electrical and optical: electrical power supply requirements and energy for light sources (if applicable).
• Temperature limits: housing temperature rise and excessive temperature protections.
• Noise level testing and acoustic requirements.
• Resistance to reprocessing (sterilization/cleaning) and leakage/ingress of water.
• Electromagnetic compatibility (EMC) and safe operating controls.
• Documentation and labelling: instructions for use, maintenance, service, marking and packaging.
• Detailed testing procedures and sampling plans, including apparatus and step‑by‑step methods (air/water supply, frequency/amplitude measurement, power output calculations).

Applications and who uses this standard

ISO 18397:2016 is essential for:

• Manufacturers of powered scalers and scaler tips - for product design, validation and CE/market conformity.
• Design and test engineers - to develop compliant handpieces (piezoelectric, magnetostrictive, ferrostrictive).
• Independent test laboratories - to perform standardized performance and safety tests.
• Regulatory and procurement teams - to evaluate product claims, safety and labelling.
• Dental clinics and purchasing managers - for selecting safe, reliable ultrasonic scalers that meet international standards.
