Shock tests may be conducted by two alternative methods described here. Both yield approximately equal shocks. Method I provides means of creating reproducible shocks by defining machine, in Fig. 1 through 7, on which tests performed. Accommodates instruments up to 4 inches in width. Method II provides means of creating reproducible shocks by defining half-sine shock pulse waveform in Fig. 9. Accommodates instruments up to 10 inches in width. Applies to electrical analog indicating instruments in C39.1-1972, but may apply to other types.
