Overview
ISO 5347-22:1997 defines general methods for accelerometer resonance testing, a critical process in the calibration of vibration and shock pick-ups. This international standard provides detailed specifications for the instrumentation and procedures used to determine the resonance frequencies of rectilinear accelerometers. These accelerometers include piezoresistive, piezoelectric, and variable capacitance types, operating within the frequency range of 50 Hz to 200 kHz.
Accurate resonance testing ensures that accelerometers used in vibration and shock measurement deliver reliable, stable readings across their operational range. The document supports consistent calibration practices to enhance the performance and safety of equipment relying on vibration analysis.
