“…Shock measurements [1], [2] have been performed internationally for a long time. In meeting the requirement to provide traceability for the International System of Units (SI), National Metrology Institutes (NMIs) and commercial companies have developed various calibration procedures utilising different shock exciters (SE) [3]- [9]. The operating principal of the SE depends largely on the intended peakacceleration level.…”

This paper describes novel design changes to the accelerometer mounting support of a commercial pneumatic shock exciter, with the aim of reducing the transverse motion the accelerometer is subjected to during shock excitation. The author describes the mounting support supplied by the manufacturer, the design changes made and the measurement data to compare the transfer motions recorded using two different mounting designs.

“…These procedures have been implemented by various NMIs [3], [5], [6], [9]. The procedures relating to part 13, the implementation thereof and the NMIs' calibration measurement capabilities were validated during the first official international shock comparison, CCAUV.V-K4 [12].…”
