16、:2007ii iiiForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject fo
17、r which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on
18、all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees ar
19、e circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held r
20、esponsible for identifying any or all such patent rights. ISO 6360-5 was prepared by Technical Committee ISO/TC 106, Dentistry, Subcommittee SC 4, Dental instruments. ISO 6360 consists of the following parts, under the general title Dentistry Number coding system for rotary instruments: Part 1: Gene
21、ral characteristics Part 2: Shapes Part 3: Specific characteristics of burs and cutters Part 4: Specific characteristics of diamond instruments Part 5: Specific characteristics of root-canal instruments Part 6: Specific characteristics of abrasive instruments Part 7: Specific characteristics of mand
22、rels and special instruments BS EN ISO 6360-5:2007iv Introduction This part of ISO 6360 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
23、the dental profession. ISO 6360 provides a general number coding system for all types of dental rotary instruments, including accessories used in connection with these rotary instruments. The benefits of this system for dentistry in its entirety will only be derived if the system is widely adopted;
24、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 desig
25、nation 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 mater
26、ials 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 specifi
27、c 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 standard
28、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 user consult ISO 6360-1 and ISO 6360-2 for general information, and in addition one of the following subsequent parts (ISO 6360-3 to ISO 6360-7)
29、 for further information on specific characteristics of instruments or groups of instruments. For the allocation of new numbers complying with ISO 6360, an application supported by a description and a drawing should be sent to the secretariat of ISO/TC 106/SC 4, Dental instruments, which keeps updat
30、ed records of all numbers currently allocated. An international group of experts will then decide on an appropriate identification number for the instrument in question, including its specific characteristics. The Secretary will inform the applicant, in due course, of the result and assist him in us
31、ing the number correctly.

32、 of ISO 6360 specifies the code numbers for specific characteristics of root-canal instruments.

36、all number. The general characteristics of the number coding system for rotary instruments including root-canal instruments are described in ISO 6360-1. The first and second groups of three digits are specified in ISO 6360-1. The shapes and designs of root-canal instruments are described in ISO 6360
37、-2:2004, Table 5, in the code number ranging from 880 to 999. The shapes and their respective numbers are specified in ISO 6360-2 as the third group. BS EN ISO 6360-5:20072 The specific characteristics of root-canal instruments are described in this part of ISO 6360. The nominal sizes of the operati
38、ve part are described in ISO 3630-1. 4.2 Groups The number coding system for root-canal instruments consists of 15 digits, separated into five groups: 000 000 000 000 000 First group: digits 1 and 2: material of operative part (see ISO 6360-1:2004, Table 1). digit 3: coating of operative part (see I

43、Code numbers for specific characteristics of root-canal instruments 5.1 General The fourth group of three digits refers to the length of the operative part and taper of the working part of root-canal instruments. The length of the operative part of a root-canal instrument is identified by the tenth
44、and eleventh digits and the taper of the working part is identified by the twelfth digit. 5.2 Length of operative part of root-canal instrument The operative part of root-canal instruments is considered as the portion from the tip to the handle or shank of the root-canal instrument. The length of th
45、e operative part is given in the locations 10 and 11. The length of the operative part of root-canal instruments is identified in millimetres. 5.3 Taper of working part of root-canal instruments The taper of the working part of root-canal instruments is given in the location 12. The taper of the wor
46、king part of root-canal instruments is identified, in percent, as the enlargement of the diameter of the working part, in millimetres per millimetre length of root-canal instrument. The taper is rounded to the nearest percent. The numbers for the taper range from zero to nine. The numbers 0 up to 8
47、indicate the taper in percent. The number 9 is used for tapers greater than 8 %. In this case, the taper is indicated by the shape number given in ISO 6360-2:2004, Table 5. EXAMPLE 1 If the taper along the working part is 0,02:1, the taper, in percent, is 2 %. The code number for these root-canal in
48、struments is 2. EXAMPLE 2 Taper sizes of 10 % and 12 % are identified in the digits for the shape and design (i.e. digits 7 to 9) by different shape numbers (see ISO 6360-2:2004, Table 5). The code number for these root-canal instruments is 9. EXAMPLE 3 If a root-canal instrument has no taper (i.e.
49、the taper is 0 %), the twelfth digit is 0. The code number for these root-canal instruments is 0. EXAMPLE 4 If a root-canal instrument has an irregular shape (e.g. arc shape), or has more than one taper, the twelfth digit is 0. The code number for these root-canal instruments is 0.
