Introduction
This section is YY/T Section 60873 of. In the field of dental professionals around the world, manufacturing a wide range of dental rotary instruments, including Endodontic instruments.
This section of various types of dental rotary instruments, including its annex connected to provide a common set of digital coding system.
Direct sense of the digital encoding system. unified standard dental rotary instruments in that field, by querying the system catalog to facilitate access Information about the device. Thus requiring manufacturers and distributors of dental products refer to this standard.
This standard is to be dental equipment production, circulation and dental professional users, the demand for dental instruments and design of the overall classification developed. by Instrument for identifying generic and specific features or devices encoded digital packet 15, is applicable to all established a total dental rotary instruments Encoding system.
The first group to identify the material for the three digital instrument working portion.
Lever handle and a second group of three digits to identify the instruments, and the overall size of the device. Group 3 of 3 for digital shape recognition device.
The fourth group of three figures for proprietary feature recognition device group.
Group 5 3 numerals are used to identify the nominal size of the working portion of the instrument.
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 coding and features, users 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.
1 Scope
YY/T 0873 provisions of this section for Dental rotary - encoded digital grinding equipment characteristics, which is located 15-digit coding system EC in the fourth group of three figures, which encodes the principle of giving described in this standard Part 1 and Part 2. This section also applicable to a dental abrasive polishing tool.
