DIN Standards Committee Dentistry

Overview

This standard specifies the coupling between handpieces and motors connected to dental units. This standard specifies the nominal dimensions, tolerances and the extraction force of coupling systems for use between handpiece and motor which supply the handpiece with water, air and light and rotation energy. For this purpose the coupling systems are classified into the following types: - Type 1: coupling system for straight and angle handpieces and motors without internal spray supply and without light supply; - Type 2: coupling system for straight and angle handpieces and motors with internal spray supply and without light supply; - Type 3: coupling system for straight and angle handpieces and motors with internal spray supply and with light supply; - Type 4: coupling system for straight and angle handpieces and motors without internal spray supply and with light supply. The International Standard has been prepared by ISO/TC 106/SC 4/WG 7 "Dental Handpieces" (secretariat: DIN), in collaboration with CEN/TC 55 "Dentistry" (secretariat: DIN). Working Group NA 014-00-05-05 AK HKL-Systeme ("Dental HKL systems") of NA 014-00-05 AA Zahnärztliche Ausrüstung ("Dental equipment") at NADENT is responsible at DIN.
