ISO 5347 comprises a series of documents dealing with methods for the calibration of vibration and shock pick-ups.
This part of ISO 5347 lays down detailed specifi-cations for the instrumentation and procedure to be used for primary calibration of rectilinear accele-rometers using laser interferometry for dynamic dis-placement measurements.
It is applicable for a frequency range from 20 Hz to 5 000 Hz and a dynamic range from 10 m/s to 1 000 m/s (frequency-dependent).
The limits of uncertainty applicable are as follows:
±0,5 % of reading at reference frequency (160 Hz or 80 Hz) and reference amplitude (100 m/s or 10 m/s) and reference amplifier gain setting;
±1 % of reading for frequencies ≤ 1 000 Hz;
±2 % of reading for frequencies > 1 000 Hz.
