7.2.4 Operating Shock

N o permanent damage will occur to the drive when subjected to a 10 G half sine wave shock pulse of
11 milliseconds duration.

N o permanent damage will occur to the drive when subjected to a 10 G half sine wave shock pulse of
2 millisecond duration.

The shock pulses are applied in either direction in each of three mutually perpendicular axis, one axis at a
time.

7.2.5 Nonoperating Shock

Translational Shock

N o damage will occur if the un-packaged drive is not subjected to a square wave shock greater than a
"faired" value of 35 Gs applied to all three axis for a period of 20 milliseconds, one direction at a time.

N o damage will occur if the un-packaged drive is not subjected to an 11 millisecond half sine wave shock
greater than 70 Gs applied to all three axis, one direction at a time.

N o damage will occur if the un-packaged drive is not subjected to a 2 millisecond half sine wave shock
greater than 125 Gs applied to all three axis, one direction at a time.

Rotational Shock

N o damage will occur if the un-packaged drive is not subjected to an 11 millisecond half sine wave shock
greater than 7,000 radians per second squared applied to all three axis, one direction at a time.

N o damage will occur if the unpackaged drive is not subjected to a 2 millisecond half sine wave shock
greater than 15,000 radians per second squared applied to all three axis, one direction at a time.

7.3 Contaminants

The corrosive gas concentration expected to be typically encountered is Subclass G1; the particulate environ-
ment is expected to be P1 of C-S 1-9700-000 (1/89).
