Campaign to compare the procedures and results, using the laser interferometry method, for the absolute calibration of the medium frequency accelerometers.
Principle: measurement of the longitudinal sensivity
Equipment: - two piezo electric standards according to:
Bruel & Kjaer 8305 (measurement on the top),
Endevco 2270 M8 (measurement on the bottom).
- the same accceleromters in circulation.
Limits : - discrete frequency from 10 Hz to 10 kHz
- discrete g's level from 0,5 to 800 m/s2
-Testing: End of the first 1993 semester (round robin).
Schedule: End of the second 1993 semester (report).
-We hope the collaboration of other European countries in particular the one of PTB(DE).
