Application Summary AI generated

This standard specifies a calibration method for accelerometers using model-based parameter identification, enabling the determination of their sensitivity, frequency response, and other dynamic characteristics without requiring a reference transducer. It is applied in metrology laboratories and industrial testing environments for high-precision calibration of accelerometers used in vibration and shock measurements, such as in aerospace, automotive, and structural health monitoring. The method is particularly useful for in-situ or field calibration where traditional back-to-back comparison methods are impractical.
