BS EN IEC 60565‑2 is a safety standard on hydrophones. BS EN IEC 60565‑2 specifies the methods for low-frequency pressure calibration of hydrophones at frequencies from 0,01 Hz to several kilohertz depending on the calibration method. Hydrophones are calibrated periodically in order to maintain a valid calibration status.
BS EN IEC 60565‑2 on hydrophones is relevant to:
A hydrophone is an electroacoustic transducer that produces electrical voltages in response to water-borne pressure signals. BS EN IEC 60565‑2 allows you to establish the procedures for low-frequency pressure calibrations of hydrophones in the frequency range from 0,01 Hz to several kilohertz to ensure the correctness of the calibrations, the hydrophones to be calibrated are "rigid" hydrophones with small size compared to the acoustic wavelength, and are not sensitive to vibration when calibrated.
BS EN IEC 60565‑2 provides principles, procedures, and uncertainties of physical calibrations such as hydrostatic excitation, piezoelectric compensation, pistonphone, vibrating column, static pressure transducer, etc., and reciprocity calibrations in acoustic couplers. Calibrations are to be carried out using one of these methods, depending on the different principles to be used, and its limitations to the sound field, and the frequency range.
Overall, BS EN IEC 60565‑2 is useful as it assists with the procedures for low-frequency pressure calibration which can help you out in your business.
