21、zation 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 for which a technical committee has been establishe

22、d 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 all matters of electrotechnical standardization.

23、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 are circulated to the member bodies for voting. Pub

24、lication 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 responsible for identifying any or all such patent

25、 rights. ISO 6360-3 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: General characteristics Part 2: Shapes Part 3: Specif

26、ic characteristics of burs and cutters Part 4: Specific characteristics of diamond instruments Part 6: Specific characteristics of abrasive instruments Part 7: Specific characteristics of mandrels and special instruments The following part is under preparation: Part 5: Specific characteristics of ro

27、ot-canal instruments EN ISO 6360-3:2005vIntroduction 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 the dental pr

28、ofession. 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; manufacturers

29、 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 thes

30、e 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 t

31、he 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 characteristi

32、cs 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 rot

33、ary 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 subsequent parts (ISO 6360-3 to ISO 6360-7) for further information

34、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 updated records of all numbers

35、 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 using the number correctly.

37、 numbers for specific characteristics of burs, finishing burs, cutters and surgical instruments, which refer to the type of toothing on the working part of the instrument. This three digit number appears in the locations 10 to 12 of the 15-digit overall number and forms the fourth group of three dig

38、its in the 15-digit overall number, the principles of which are explained in ISO 6360-1 and 6360-2. NOTE In addition to terms for rotary instruments and accessories used in two of the three official ISO languages (English, French and Russian) this part of ISO 6360 gives the equivalent terms in the G

39、erman language; these are published under the responsibility of the member body for Germany (DIN). However, only the terms given in the official languages can be considered as ISO terms. 2 Normative references The following referenced documents are indispensable for the application of this document.

40、 For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

41、m for rotary instruments Part 2: Shapes 3 Terms and definitions For the purposes of this document, the terms and definitions given in ISO 6360-1 and the following apply. 3.1 primary toothing first toothing toothing on the working part of the instrument which is the deepest toothing NOTE The orientat

42、ion of the helix is either in the left or right direction. 3.2 secondary toothing toothing on the working part of the instrument with a toothing depth less than the primary toothing 3.3 crosscut helicoidal crosscut spiral cut secondary toothing which is formed by a single uninterrupted helicoidal cu

43、t EN ISO 6360-3:20052 NOTE Crosscuts can affect only the cutting edges of the primary toothing or can be lowered down to the root of the primary toothing or even deeper. The pitch of the helix may be varied to achieve finer or coarser crosscuts. A crosscut might be oriented either in left or right d

44、irection. 3.4 serpentine cut special case of the crosscut 3.5 x-cut double cut staggered cut secondary toothing which crosses the primary toothing NOTE The angle of the helix is similar to the angle of the primary toothing in most cases. The orientation of the helix is either the same as the orienta

45、tion of the primary toothing or in the opposite direction. 3.6 diamond cut secondary toothing with a toothing depth similar to the primary toothing NOTE The angle of the helix is similar (approximately 45) to the angle of the primary toothing but the orientation is in the opposite direction. 4 Code

46、numbers for specific characteristics 4.1 General The general characteristics of the number coding system for rotary instruments are described in ISO 6360-1. The first and second group of three digits of the 15-digit overall number are specified in ISO 6360-1. The shapes of rotary instruments and the

47、ir respective numbers are specified in ISO 6360-2 as the third group. The fourth group of three digits identifies specific characteristics for groups of instruments. The specific characteristics of burs, finishing burs, cutters and surgical instruments refer to the type of toothing on the working pa

48、rt of the instruments. This is designated by a three-digit number, which appears in the locations 10 to 12 of the overall 15-digit code number. The code numbers identify the type of toothing of burs and cutters, including surgical instruments. 4.2 Type of toothing The type of toothing on the working

49、 part is based on the following: a) type of instrument: bur, finishing bur, cutter, surgical instrument; EXAMPLE The toothing designations are: bur toothing, finishing bur toothing, cutter toothing, surgery toothing. b) type of primary toothing: 1) direction of primary toothing: straight, left helicoidal, right helicoidal; 2) cutting direction of primary toothing: left cutting, right cutting; 3) grade of fineness of primary toothing: very fine, fine, medium, coarse, very coarse; EXAMPLE The characteristics of the primary toothing ar
