IEC TS 62903:2018是一项技术规范，a)建立了超声换能器标定的自由场会聚球面波自互易法，b)建立使用自互易法确定换能器的电声参数和声输出功率所需的测量条件和实验程序，c)建立用于检查这些换能器的互易性和聚焦场的线性范围的标准，以及d)为评估辐射电导的总体测量不确定度提供指导信息。本文件适用于:i)在线性振幅范围内工作的没有中心孔的圆形球面弯曲凹聚焦换能器，ii)在0.5 MHz至15MHz的频率范围内的测量，以及iii)在线性振幅范围内的聚焦场中的声压振幅。

IEC TS 62903:2018, which is a Technical Specification,
a) establishes the free-field convergent spherical wave self-reciprocity method for ultrasonic transducer calibration,
b) establishes the measurement conditions and experimental procedure required to determine the transducer's electroacoustic parameters and acoustic output power using the self-reciprocity method,
c) establishes the criteria for checking the reciprocity of these transducers and the linear range of the focused field, and
d) provides guiding information for the assessment of the overall measurement uncertainties for radiation conductance.
This document is applicable to:
i) circular spherically curved concave focusing transducers without a centric hole working in the linear amplitude range,
ii) measurements in the frequency range 0,5 MHz to 15 MHz, and
iii) acoustic pressure amplitudes in the focused field within the linear amplitude range.
