| 規格概要 | IEC TS 62903:2023 is available as IEC TS 62903:2023 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC TS 62903:2023: 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: 1) circular spherically curved concave focusing transducers without a centric hole working in the linear amplitude range, 2) measurements in the frequency range 0,5 MHz to 15 MHz, and 3) acoustic pressure amplitudes in the focused field within the linear amplitude range. Characterization and sensitivity calibration of hydrophones using the reciprocity method are not addressed in this document but covered in IEC 62127-2 and IEC 60565-1. IEC TS 62903:2023 cancels and replaces the first edition published in 2018. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Several quantities are recognized as complex-valued quantities in the definitions and in the main text. b) Annex I was added to provide typical measurement ranges and to provide example calibration results. |
