Foreword
This standard replaces GB/T 15261-1994 "ultrasonic measurement of human tissue material acoustic characteristics of imitation."
Compared with the standard GB/T 15261-1994 The main changes are as follows.
--- Standard English name more standardized;
--- Sample for measurement equipment and technical requirements more rigorous and detailed presentation;
--- Consistent with international practice, the standard temperature measurement conditions employed from 25 ℃ to 23 ℃;
--- Density measurements instead GB/T 4472-1984 buoyancy and the flask method;
--- Measuring sound attenuation coefficient cancel single sample method, only to double sample method;
--- Correlation processing sound attenuation coefficient versus frequency by general linear fitting to fitting a straight line through the origin of coordinates and curve fitting
Two kinds;
--- Increased backscatter coefficient measurement of content;
--- Measuring the speed of sound and attenuation coefficient increases uncertainty analysis section;
--- Appendix increases the density of water, sound speed and attenuation coefficient versus temperature of the contents;
--- An increase in the reference section.
The Standard Appendix A, Appendix B, Appendix C, Appendix D, Appendix E are informative appendices.
This standard was proposed by the State Food and Drug Administration.
This standard by the National Standardization Technical Committee medical appliances (SAC/TC10) centralized.
This standard was drafted. Institute of Acoustics.
The main drafters of this standard. Cattle Fengqi, Zhu Chenggang, Cheng Yang.
This standard was first published in 1994.
