ISO 3964:2016 pdf free.Dentistry一Coupling dimensions for handpiece connectors
ISO 3964 specifies the coupling between handpieces and motors connected to dental units.
ISO 3964 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.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 1942, ISO 14457 and the following apply.
3.1 coupling dimension
description of the dimensions of connectors between air- and electrical motors and straight and angled handpieces, used to connect and supply the handpiece system
3.2 coupling system
combination of connector parts between air- and electrical motors and straight and angled handpieces,used to connect and supply the handpiece system
4 Classification
For the purpose of this International Standard, coupling systems are classified into the following types:
一Type 1: coupling system for straight and angle handpieces and motors without internal spray supply and without light supply;
一Type 2: coupling system for straight and angle handpieces and motors with internal spray supply and without light supply;
一Type 3: coupling system for straight and angle handpieces and motors with internal spray supply and with light supply;
一Type 4: coupling system for straight and angle handpieces and motors without internal spray supply and with light supply.
5 Requirements
5.1 General
Types of the coupling for handpieces and for motors are specific parts of dental handpieces.
Requirements for dental handpieces are specified in ISO 14457.
5.2 Dimensions
The dimensions and the configuration of handpiece-sides and motor-sides shall be as specified in Figure 1, Figure 2, Figure 3, Figure 4, Figure 5, Figure 6, Figure 7 and Figure 8 with coupling dimensions X1 and X2 as specified in Table 1.ISO 3964 pdf download.
