YY/T 0751-2009Ultrasonics—Dental descaler systems—Measurement and declaration of the output characteristics (English PDF)

Foreword

This standard is equivalent to using the International Electrotechnical Commission standard IEC 61205:1993 "ultrasonic scaler device output characteristic measurement and disclosure." The standard IEC 61205:1993 only made a very small number of editorial changes did not affect the degree of consistency. The Standard Annexes A and B are informative appendices.

This standard by the standardization of medical ultrasound equipment for medical appliances National Standardization Technical Committee Technical Committee (SAC/TC10/SC2) Centralized.

Introduction

Ultrasonic scaler equipment widely used in spot and remove calculus from the teeth, although the mode of action of such devices are not fully carry out special Zheng explained, but the scavenging effect ultrasonic scaler device depends on the amplitude of the vibration. The purpose of this standard is the fundamental vibration ultrasonic scaler device regulations Characteristics of standard measurement methods and technical requirements. In this standard does not consider security issues and biological effects of ultrasound output. Ultrasonic scaler equipment Measuring and publishing output characteristics

1 Scope

This standard specifies.

--- Ultrasonic scaler device basic non-thermal output characteristics;

--- Measurement equipment ultrasonic scaler output performance;

--- By the ultrasonic scaler equipment manufacturer's published output characteristics.
