The scope of this standard includes measurement of mobility,accelerance,or dynamic compliance,either as a driving-point measurement,or as a transfer measurement.It also applies to the determination of the arithmetic reciprocals of those ratios such as free effective mass.Although excitation is applied at a single point,there is no limit on the number pf points at which simultaneous measurements of the motion response may be made.Multiple response measurements are required,for example,for modal analyses.

This standard applies to the auxiliary equipment used between a shock or vibration transducer and the final indicator,recorder,or signal processor.This document presents a standard format for indicating pertinent characteristics but does not in any respect become a standard on the performance of the equipment. Since this standard was prepared to cover a wide variety of equipment in considerable detail,not all items will be pertinet to a specific piece of equipment.Also,it is not the intent of this standard to establish an ironclad rule as to which of the characteristics should be characteristics are emphasized.
