scope:

Five methods have. been selected as standard methods for the calibration of acceleration velocity, and displacement pickups. They are described in Section 4 of this standard. It is impracticable to calibrate all pickups by one standard method over the entire frequency and amplitude range of vibrations and shocks to be measured by the pickups. Several methods are accordingly described. Each method is limited to u range of frequency and amplitude, and to the weight ofpickup that can be calibrated. The limitations may mclude, m addit1on, other variables such as volume of the pickup and temperature of operation.

Purpose. This standard is designed to acquaint the user with the general principles of calibration of shock and vibration pickups and to describe concisely several standard methods which have proven to give reliable and reproducible results. Further details concerning these methods are given in the Appendix. Also, other methods that have not as yet reached the stage of development of the standard methods are described briefly in the Appendix.
