YY/T 0110-2009Piezoelectric materials for medical ultrasound (English PDF)

Foreword

Instead of the standard YY/T 0110-1993 "medical ultrasound piezoelectric ceramic material." The main changes in the standard of YY/T 0110-1993 compared as follows.

a) According to the latest national standards updated normative references.

b) According to the development of medical ultrasound piezoelectric ceramic material, although a lot of new materials to meet the old standard of freedom relative permittivity to Seeking, but piezoelectric strain constant, the mechanical quality factor and other parameters of the old standards do not match, especially in the lead titanate is defined as the power The rate of emission material less accurate. Therefore, according to GB/T 3388 provisions of the material features, combined with medical ultrasonic piezoelectric ceramic material Material characteristics of medical ultrasonic piezoelectric ceramic materials have been reclassified.

c) main performance requirements for medical ultrasonic piezoelectric ceramic material, increasing the longitudinal electromechanical coupling coefficient k 33, the longitudinal length of the stretching vibration Frequency constant N3 and the longitudinal sound velocity Vp 3D, thickness of the sound velocity Vp tD. error.

e) Amendment of the inspection rules, according to medical ultrasonic piezoelectric ceramics production characteristics, test methods for materials added to the sample system For, taking into account the small number of samples, so the test acceptance criteria were direct statements.

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

This standard is mainly drafted by. Kunshan Risheng Electronics Co., Ltd., the State Food and Drug Administration of Quality Supervision, Inspection Hubei Medical Devices Test center.

1 Scope
