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 specifications for the instrumentation and procedure to be used for primary calibration of rectilinear accelerometers using laser interferometry for dynamic displacement measurements.
It is applicable for a frequency range from20 Hz to 5 000 Hz and a dynamic range from10 m/s2 to 1 000 m/s2 (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/s2 or 10 m/s2) and reference
- amplifier gain setting;
- ± 1 % of reading for frequencies ≥ 1 000 Hz;
- ± 2 % of reading for frequencies > 1 000 Hz.
