15、ber 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 organizations, governmen
16、tal 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 the ISO/IEC Direc
17、tives, 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 the member bodi
18、es 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 rights. ISO 9168 was prepared by Technical Committee ISO/TC 106, Dentistry, Subcommittee S

This International Standard specifies four types of hose connector for use between air driven dental handpieces and the flexible hoses of the dental unit which supply the handpieces with water, air and
22、 light, and provide for exhaust. 2 Normative references The following referenced documents are indispensable for the application of this document.

Requirements for dental handpieces are specified in the relevant product standards. NOTE R
27、elevant product standards for dental handpieces are e.g. ISO 7785-1, ISO 13294 and ISO 15606. 5.2 Dimensions The dimensions, the outlet configuration and the use of the outlets shall be as specified in Figure 1, Figure 2, Figure 3 and Figure 4. The thread characteristics for Type 1, Type 2 and Type
28、3 shall be as specified in Table 1. The thread characteristics for Type 4 (M12 0,5) shall be in accordance with ISO 261. Testing shall be carried out in accordance with 7.1. 5.3 Resistance to reprocessing Hose connectors shall be capable of withstanding a minimum of 250 reprocessing cycles as define
29、d in the manufacturers instructions for use without deterioration in appearance or performance. Quick connectors with and without lights supply, which are not permanently fixed to the instrument, shall be capable of withstanding the reprocessing procedure as given in the manufacturers instructions.
30、In this case the requirements of ISO 7494-1 are applicable. Testing shall be carried out in accordance with 7.2.
