The work of preparing International Standards is normally carried out
15、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, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO coll
16、aborates 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 Directives, Part 2. The main task of technical committees is to prepare International St
17、andards. 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 bodies casting a vote. Attention is drawn to the possibility that some of the elements
18、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 9173-2 was prepared by Technical Committee ISO/TC 106, Dentistry, Subcommittee SC 4, Dental instruments. ISO 9173 consists of the following parts, under the gene
19、ral title Dentistry Extraction forceps: Part 1: General requirements and test methods Part 2: Designation BS EN ISO 9173-2:2010ISO 9173-2:2010(E) iv ISO 2010 All rights reservedIntroduction Dental extraction forceps are used for the extraction of teeth. The majority of extraction forceps are for use
20、 on both sides and for more than one tooth, e.g. for all upper or lower premolars, for upper central incisors and upper canines (and larger lateral incisors), for upper lateral incisors and for upper deciduous incisors and canines. Some extraction forceps for upper molars and some extraction forceps
21、 for lower third molars are specially designed for the type of tooth and the side concerned. Some extraction forceps are only for roots. In order that the dentist and/or his assistant can order the correct extraction forceps for an intended clinical purpose a global designation system is necessary.
22、General requirements and test methods for extraction forceps are specified in ISO 9173-1.
