Vibrations
Vibration test in accord‐
ance with IEC 60068-2-6
(sinusoidal)
Type of vibration: frequency sweeps with a rate of
change of 1 octave/minute.
10 Hz ≤ f < 58 Hz, constant amplitude 0.075 mm
58 Hz ≤ f < 500 Hz, constant acceleration 1 g
Duration of vibration: 10 frequency sweeps per axis
in each of three axes perpendicular to each other.
Shock
Shock test in accordance
with IEC 60068-2-29
Type of shock: half-sine
Severity of shock: 10 g peak value, 6 ms duration
Direction of shock: 100 shocks in each of the 3 axes
arranged vertically to each other.
