3. 3.1. TEST METHODS Examination of Product Specimens were visually examined and no evidence of physical damage detrimental to product performance was observed. 3.2. Termination Resistance, Specified Current The potential drop of mated contacts assembled in housing was measured and the resistance calculated. 3.3. Termination Resistance, Dry Circuit Dry circuit termination resistance measurements were made using a 4 terminal measuring technique. The test current was maintained at 100 milliamperes maximum with a 50 millivolt maximum open circuit voltage. 3.4. Dielectric Withstanding Voltage A test potential of 5 kVAC was applied between the adjacent contacts of mated specimens. This potential was applied for 1 minute and then returned to zero. 3.5. Insulation Resistance Insulation resistance was measured between adjacent contacts of mated specimens. A test voltage of 500 volts DC was applied for 2 minutes before the resistance was measured. 3.6. Temperature Rise vs Current Temperature rise curves were produced by measuring individual contact temperatures at different current levels. These measurements were plotted to produce a temperature rise vs current curve. Thermocouples were attached to individual contacts to measure their temperatures. The ambient temperature was then subtracted from this measured temperature to find the temperature rise. When the temperature rise of consecutive readings did not differ by more than 1/C, the temperature measurement was recorded. 3.7. Vibration Mated specimens were subjected to sinusoidal vibration, having a simple harmonic motion with an amplitude of 1.5 mm [0.06 in], double amplitude. The vibration frequency was varied uniformly between the limits of 10 and 55 Hz and returned to 10 Hz in 1 minute. This cycle was performed 120 times in each of 3 mutually perpendicular planes for a total vibration time of 6 hours. Specimens were monitored for discontinuities of 10 microseconds or greater using a current of 100 milliamperes DC. 3.8. Physical Shock Mated specimens were subjected to a physical shock test having a sawtooth waveform of 50 gravity units (g peak) and a duration of 10 milliseconds. Three shocks in each direction were applied along the 3 mutually perpendicular planes for a total of 18 shocks. Specimens were monitored for discontinuities of 10 microseconds or greater using a current of 100 milliamperes DC.

3.9. Mating Force The force required to mate individual specimens was measured using a tensile/compression device with a free floating fixture and a rate of travel of 12.7 mm [.5 in] per minute. The maximum average force per contact was calculated. 3.10. Unmating Force The force required to unmate individual specimens was measured using a tensile/compression device with a free floating fixture and a rate of travel of 12.7 mm [.5 in] per minute. The minimum average force per contact was calculated. 3.11. Contact Insertion Force Contact insertion force was measured by applying an increasing force to each contact until the contact was properly seated in the housing. 3.12. Contact Retention Force An axial load of 66.7 N [15 lbf] was applied to standard contacts and 111.2 N [25 lbf] for high retention contacts and held for 60 seconds. The force was applied in a direction to cause removal of the contacts from the housing. 3.13. Crimp Tensile The force load was applied to each specimen using a tensile/compression device with the rate of travel at 25.4 mm [1 in] per minute. 3.14. Durability Specimens were manually mated and unmated 50 times. 3.15. Housing Panel Retention Specimens were mounted rigidly into a test panel. An axial load of 333.6 N [75 lbf] was applied to each end of the specimen in a direction which would cause the specimen to dislodge from the panel. 3.16. Housing Lock Strength An axial load of 133.4 N [30 lbf] was applied to mated specimens in a manner which would cause the specimen locking latches to disengage. 3.17. Thermal Shock Mated specimens were subjected to 25 cycles of thermal shock with each cycle consisting of 30 minute dwells at -55 and 85/C. The transition between temperatures was less than 1 minute. 3.18. Humidity/temperature Cycling Mated specimens were exposed to 10 cycles of humidity/temperature cycling. Each cycle lasted 24 hours and consisted of cycling the temperature between 25 and 65/C twice while maintaining high humidity. During 5 of the first 9 cycles, the specimens were exposed to a cold shock of -10/C for 3 hours and vibration.
