| Abstract: | This paper describes the major technical improvements in drafting IEC TS 62903 Ed1.0:2018 based on GB/T 32522-2016 Acoustics-Electroacoustical characteristics and measurements of spherically focused piezoelectric ultrasonic transducers, in which the self-reciprocity calibration method is defined as the national standard method in China. These improvements include the theoretical expression, the corrections of some error concepts, applications of new research results, the experimental verification in full frequency range, and the evaluation of measurement uncertainty etc. |
