GSO …./….(1) comprises a series of documents dealing with methods for the calibration of vibration and shock pick-ups. This standard lays down detailed specifications for the instrumentation and procedure to be used for primary calibration of accelerometers. Using centrifuge calibration. This standard applies to rectilinear accelerometers with zero-frequency response, mainly of the strain gauge or piezoresistive type, and to primary standard and working pick-ups. It is applicable for a calibration range from 10 m/s2 to 1 000 m/s2 (higher accelerations possible) at 0 Hz. The limits of uncertainty applicable are ± 1% of reading.
