Shock may be applied in the X, Y, or Z axis. Shock is not to be repeated more than once every 2 seconds.
b. Operating—abnormal
Equipment, as installed for normal operation, does not incur physical damage while subjected to intermit-
tent shock not exceeding 40 Gs at a duration of 11 msec (half sinewave). Shock occurring at abnormal lev-
els may promote degraded operational performance during the abnormal shock period. Specified
operational performance will continue when normal operating shock levels resume. Shock may be applied
in the X, Y, or Z axis. Shock is not to be repeated more than once every 2 seconds.
