Ultrasonics. Measurements of electroacoustical parameters and acoustic output power of spherically curved transducers using the self-reciprocity method
BS PD IEC/TS 62903 – Ultrasonics. Measurements of electroacoustical parameters and acoustic output power of spherically curved transducers using the self-reciprocity method
BS PD IEC/TS 62903:2018, which is a Technical Specification,
a) establishes the free-field convergent spherical wave self-reciprocity method for ultrasonictransducer calibration,
b) establishes the measurement conditions and experimental procedure required todetermine the transducer’s electroacoustic parameters and acoustic output power usingthe self-reciprocity method,
c) establishes the criteria for checking the reciprocity of these transducers and the linearrange of the focused field, and
d) provides guiding information for the assessment of the overall measurement uncertaintiesfor radiation conductance.
