15、ticipate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. The IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreeme
16、nt between the two organizations. The formal decisions or agreements of the IEC on technical matters, prepared by technical committees on which all the National Committees having a special interest therein are represented, express, as nearly as possible, an international consensus of opinion on the
17、subjects dealt with. They have the form of recommendations for international use published in the form of standards, technical reports or guides and they are accepted by the National Committees in that sense. In order to promote international unification, IEC National Committees undertake to apply I
18、EC International Standards transparently to the maximum extent possible in their national and regional standards. Any divergence between the IEC Standard and the corresponding national or regional standard shall be clearly indicated in the latter. International Standard IEC 1205 has been prepared by
19、 IEC technical committee 87: Ultrasonics. The text of this standard is based on the following documents: Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table.

20、TRODUCTION Les dtartreurs dentaires faisant appel aux ultrasons sont largement utiliss pour liminer la plaque et le tartre sur les dents. Bien que le mode daction de ces dispositifs ne soit pas parfaitement caractris, leurs performances de nettoyage dpendent de lamplitude des vibrations. La prsente
21、Norme Internationale a pour but de dfinir des mthodes de mesure normalises et les caractristiques vibratoires essentielles des dtartreurs dentaires ultrasoniques.

22、ntal descalers are widely used for removing plaque and calculus from teeth. Although the mode of action of these devices has not been well characterized, the cleaning efficiency of ultrasonic dental descalers depends on the vibration amplitude. The purpose of this International Standard is to define
23、 standard methods of measurement and specification of the essential vibration characteristics of ultrasonic dental descalers. Questions of safety and biological effects of the output are not treated in this standard. -8- 1205 0 CEI:1993 ULTRASONS - SYSTMES DE DTARTREURS DENTAIRES - Mesure et dclarat

IEC 782: 1984, Measurements of ultrasonic magnetostrictive transducers 3 Definitions of output characteristics For the purposes of this International Standard, the following definitions apply. 3.1 half-excursion force: Force with which the tip must contact a glass slide so
34、 as to reduce the primary tip vibration excursion to 50 o/o of the value it has when the contact force is 0,15 N f 0,02 N. 3.2 primary tip vibration excursion: Peak-to-peak displacement of the applicator in the direction of maximum amplitude, at a point on the applicator not more than 1 mm from its tip. 3.3 tip vibration frequency: Fundamental frequency at which the tip of the applicator oscillates.
