Military Standard MIL-STD-810E

Vibration Test
The Vibration test was performed in accordance with MIL-STD-810E, Method 514.4,Procedure I, Category 6 (Helicopter) and Category 8 (Ground Mobile) for operational condition. To approximate rigid mounting, the MobiTough was clamped to analuminum plate and was then subjected to the following levels of vibration:
Ground Vehicle Test (Category 8)
A sine vibration with logarithm sweep from 5 - 200Hz was conducted. 5-6.25Hz, 1.0inch (double amplitude), 6.25-200Hz, 2G, 12 minutes per cycle (5-200-5). The test was 5.5 hours along each of three orthogonal axes. This test was conducted inaccordance with MIL-STD-810C, Method 514, Procedure VIII.
Helicopter Vibration (Category 6)
The helicopter vibration test duration was one hour along each of three orthogonalaxes. The test was conducted in accordance with MIL-STD-810E, Method 514.4,Category 6.

Water Resistance
Performed in accordance with MIL-STD-810E, Method 506.3, Procedure I (Blowing Rain).the water resistance test subjected the unit to 114mm/hr rainfall for 30 minutes. TheROCKY was tested while on and fully operational with the LCD open and with port covers in place. The ROCKY was opened following testing to inspect for water intrusion.No water penetrated the unit.

Humidity
Performed over 10 days, the test exposed ROCKY to humidity for 24 hours at a time.The units were tested at the end of the fifth and tenth day. The temperature cycles wereset between 86°F and 140°F. The Humidity test was performed in accordance withMIL-STD-810E, Method 507.3, Procedure III (Aggravated). The ROCKY exhibitedno abnormalities following testing.

Salt Fog
The Salt Fog test was performed according to MIL-STD-810E, Method 509. The ROCKY was placed in a salt fog chamber for 48 hours with the salt fog spray at35°C. The ROCKY continued to operate following the Salt Fog testing.

High Temperature
Two High Temperature tests were conducted in accordance with MIL-STD-810E, Method501.3, In Procedures I (Storage) the test subjected the unit to 12 hours dwell time of 23°Cand 12 hours dwell time of 60°C in each cycle, 24 hours per cycle, total of seven cycles.In Procedure II (Operation) the test subjected the unit to three cycles of 12 hours at 23°Cand 12 hours at 50°C.

Low TemperatureThe Low Temperature test was performed according to MIL-STD-810E, Method 502.3, Procedures I (Storage) and II (Operation). Procedure I (Storage) called for the unit tobe stored in -20°C temperature for 4 hours. Procedure II (Operation) required the unit to be operating at 0°C for 4 hours. The ROCKY's continued to boot and operate followingeach test without any signs of abnormalities.

Shock
The Shock test was performed in accordance with MIL-STD-810E, Method 516.4 Procedure 1.Shock tests are performed to assure that material can withstand the relatively infrequent, non-repetitive shocks or transient vibrations encountered in handling, transportation andservice environment. (According to MIL-STD 810E) The ROCKY continued to boot up andoperate following the shock test exposure at 40G. 11ms Half saw wave.

This standard establishes the design requirements for the control of the electromagnetic emission and susceptibility characteristics of electronic, electrical, and electromechanical equipment and subsystems designed or procured for use by activities and agencies of the Department of Defense. Such equipment and subsystems may be used independently or as an integral part of other subsystems or systems. Data item requirements are also included.
