5.1.2. Shipping and Storage:
-40ºC to + 70ºC
5.1.3. Operating Humidity
55ºC/85% RH (non-condensing)
5.2. Durability:
Mate and unmate samples for 50 cycles at a rate of 500cph (max), using the same
socket. One package is to be used for 1st and 51st cycles. Measure electrical
resistance when mated in 1
st
and 51
st
cycles. A spare package shall be used for 2nd
through 50th cycles. A pair of new packages are to be used for each of the socket
samples.
5.3. Shock:
Tested at 50G, 11ms duration, Trapezoidal waveform. Three shocks applied in each
of three perpendicular axes (18 total). The socket must be mated with the mechanical
sample outlined in Section 6.8.4 and retained with mechanical supports outlined in
Section 3.2. The total minimum velocity change shall be 170in/s. Figure 18
provides the schematic for this requirement.
