Technical Specification

DIN IEC/TS 62903
Ultrasonics - Measurements of electroacoustical parameters and acoustic output power of spherically curved transducers using the self-reciprocity method (IEC TS 62903:2023)

Title (German)

Ultraschall - Messungen elektroakustischer Parameter und akustischer Ausgangsleistung von sphärisch gekrümmten Wandlern nach dem Selbstreziprozitäts-Verfahren (IEC TS 62903:2023)

Procedure

Overview

This document, 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.
