24、 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 established has the right to be represented on that committee. International organiza

25、tions, 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. International Standards are drafted in accordance with the rules given in t

26、he 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. Publication as an International Standard requires approval by at least 75 % of

27、 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.

This second edition cancels and replaces the first edition (ISO 7711-3:1992), which has been technically revised to include the following changes: a) reduction from 7 classes for the colour code to 6 classes (deletion of “very fine”); b) introduction of an abb

29、reviation for the colour code.

30、ll rithgs reresvde Introduction The first edition of this part of ISO 7711 was published in 1992. It was the first attempt to group the diamond grit used for dental rotary instruments and to specify a designation and a colour code for the grit size areas. The rapid development of the use of diamond

31、grit for dental instruments and the possibility of refined separation and thus a clearer classification of diamond grit necessitated a revision of this part of ISO 7711. This revision offers the opportunity to provide abbreviations for the terms used, to align them with similar standards for dental

32、rotary instruments.

36、Designation, colour code, grit sizes 4.1 Designation The designation of the diamond instruments in regard to the fineness of the diamond grit used shall conform with the designation given in Table 1. 4.2 Colour code The colour code complements the designation. Usage of the colour code is optional, a

37、t the discretion of the manufacturer. If colour coding is used, the colours shall be those specified in Table 1. The location on the diamond instrument where the colour is applied is at the discretion of the manufacturer. ENISO77113:2004ISO -11772:3)E(400 2 ISO 4002 All rithgs reresvde 4.3 Grain siz

The series of diamond grit

39、 sizes is designated as the D series (D 1181 to D 46), where “D” denotes diamond. NOTE Further information is given in references 13 and 15 (see Bibliography). 4.3.2 Microgrits Currently no internationally accepted method for determining or verifying the grain size distribution of microgrits for dia

40、monds is available. Therefore methods from regional standards or national standards are used. The series of diamond grit sizes is designated as the M series, where “M” denotes microgrit. NOTE Further information is given in references 12 and 14 (see Bibliography). 4.4 Grit sizes The grit sizes as sp

41、ecified in Table 1 shall be used for all types of diamond instruments. The grit sizes and their classification in regard to their fineness are selected according to relevant national or international regulations. Because of the difficulty in separating grain sizes, overlapping areas are unavoidable

42、and commonly accepted. Columns 3 and 4 indicate colour codes and their equivalent grit size ranges, respectively.
