B. Random Vibration|
Mated specimens were subjected to a random vibration test, specified by a random vibration|
spectrum, with excitation frequency bounds of 20 and 500 Hz. The spectrum was flat at 0.02 G
2
/Hz|
from 20 to 500 Hz. The root-mean square amplitude of the excitation was 3.10 GRMS. This was|
performed for 15 minutes in each of 3 mutually perpendicular planes for a total vibration time of 45|
minutes. Specimens were monitored for discontinuities of 1 microsecond or greater using a current|
of 100 milliamperes DC.|
C. Durability (Preconditioning)|
Specimens were unmated and mated 20 times at a maximum rate of 300 cycles per hour.|
D. Durability|
Specimens with 3 microinches of gold flash over 12 microinches of palladium/nickel plating were|
mated and unmated 75 times, specimens with 3 microinches of gold flash over 27 microinches of|
palladium/nickel plating were mated and unmated 150 times.|
|
E. Reseating|
Specimens were manually unmated and remated 3 times.|
F. Thermal Shock|
Specimens were subjected to 10 cycles of thermal shock with each cycle consisting of 30 minute|
dwells at -55 and 85°C with 1 minute transition between temperatures.|
G. Humidity/temperature Cycling|
Specimens were exposed to 24 humidity/temperature cycles consisting of 1 hour dwells at 25°C at|
80% RH and 65°C at 50% RH.|
H. Mixed Flowing Gas|
Mated and unmated specimens were exposed for 14 days (unmated for the first 9 days and mated|
for the final 5 days) to a mixed flowing gas Class IIA exposure. Class IIA exposure is defined as a|
temperature of 30°C and a relative humidity of 70% with the pollutants of Cl

at 200|
ppb, H

S at 10 ppb and SO

at 100 ppb.|
I. Temperature Life (Preconditioning)|
Specimens were exposed to a temperature of 105°C for 168 hours.|
J. Temperature Life|
Specimens were exposed to a temperature of 105°C for 528 hours.|
K. Thermal Disturbance|
Specimens were subjected to 10 temperature cycles with each cycle consisting of 15 minute dwells|
at 15 and 85°C with a minimum ramp time between temperatures of 2°C per minute.|
