Introduction
This section is part of a digital standard coding system for rotary instruments. All kinds of dental rotary instruments, including endodontic instruments, has been in the global scope
Produced and used by dental professionals around inside.
The standard for all types of dental rotary instruments, including accessories connected thereto, to provide a common set of digital coding system.
The use of digital coding system meaning that if the system is widely used, manufacturers and traders of dental rotary instruments by
The standard directory inquiry direct access to information about the device.
This standard is based on a dental rotary instruments of trade, production and dental professional needs, identification and classification of these instruments and the establishment of a pass
Use the system. This standard applies to all established a dental rotary instruments and easy to understand digital coding system, this system uses 15 series
Code numbers and proprietary features characterize the general instruments or instrument groups.
Group 13 digits for material identification devices working portion.
Group 23 digits used to identify the device and the total length of the lever handle and equipment.
Group 3 3 digits for shape recognition device.
Group 4 3 figures for proprietary feature recognition device group.
Group 53 digit identification device for the nominal diameter of the working portion.
Digital coding for the generic code does not provide accurate product information. This information is provided by the respective product standard dental rotary instruments.
In the application of the digital coding system to find the correct codes and characteristics, the user should see YY/T 0873.1 and YY/T 0873.2 get through
Use of information, and see the next section (YY/T 0873.3 ~ YY/T 0873.7) to obtain a device or group of devices further feature information.
