BS EN ISO 6360-7:2006 is one of a series of International Standards relating to dental rotary instruments. A wide variety of dental rotary instruments, including root-canal instruments, is manufactured throughout the world for use by the dental profession.

The benefits of this system for dentistry in its entirety will only be derived if the system is widely adopted; manufacturers of dental instruments, as well as the dental trade, are therefore requested to refer to ISO 6360 in their catalogues. This part of ISO 6360 was prepared in response to a need by the dental trade and industry and the dental profession for a universal system of classification and designation for these instruments. It establishes a comprehensive number coding system suitable for all dental rotary instruments by use of a 15-digit code number identifying general and specific characteristics of instruments or groups of instruments.
The first group of three digits identifies the materials used for the working part of instruments. The second group of three digits identifies the shanks and handles used for instruments and the overall lengths of instruments. The third group of three digits identifies the shapes of instruments. The fourth group of three digits identifies the specific characteristics for groups of instruments. The fifth group of three digits identifies the nominal diameter of the working part of the instruments.
The code numbers are generic code numbers. They do not provide exact product information. This information is given in the respective product standards for dental rotary instruments. For the application of the system and for the correct allocation of numbers or their identification, it is intended that the u...
