The test sequence is conducted by using a no-load, followed by a load sequence. The power factor of the load is 0.75 to 0.80.
Mold Stress Relief 70°C (158°F) for 7 hours.
Humidity 32°C (89.6°F), 93% humidity for 7 days (168 hours).
Cable Secureness See Table 3
Impact A device is wired with a 90" (2300mm) length of flexible cord and dropped from 30" (760mm) 8 times. The device is then conditioned for 6 hours at -25°C and immediately subjected to a repeated impact test.
Crushing 250 lbs for 1 minute. The device is then conditioned for 6 hours at -25°C and immediately subjected to a repeated crushing test.
Withdrawal Force See Table 4
Strength of Insulating Base and Support 110 of specified tightening torque on terminal screws.
Polarization Integrity Matching devices will not mate so that the ground is energized, even when polarization feature is removed and 40lb (180 N) insertion force is applied.

The pressure exerted by mating contacts of a plug and connector must be sufficient to prevent unintentional withdrawal during normal use. During the test, any locking rings or retaining means are not to be engaged.
Flammability V-2 or better per UL 94 or CSA 22.2 No. 0.6
Ambient Temperature Range Minimum: -25°C (-13°F) with impact Maximum: 90°C (194°F)
Resistance to Corrosion Ferrous parts immersed for 10 min. in a 10% solution of ammonium chloride at a temperature of 20°C
Moisture Resistance Watertight (IP67): Device immersed for 24 hours in water at a temp. of 25°C, the highest point of the device being 2" (5cm) below the water level.

Splashproof (IP44): Device is sprayed with water for 10 minutes and immediately afterwards subjected to splashing water in all directions 360°
UV Resistance Exposed plastic materials are UV stabalized.
