Environmental Considerations
5.2
As an OEM product, the Q4000 is designed to be housed in a sealed enclosure or in an environmentally
benign area, since it is not sealed against moisture ingress.
• Operating Temperature
o –40C to 85C
• Storage Temperature
o –40C to 85C.
• Low Pressure
o Up to 4 hours at 15000 ft elevation pressure
• Humidity
o Relative humidity range of 0% to 95% non-condensing at 65C
o Humidity Test in Orbcomm Spec E25050102 REV D is per MIL SPEC 810E, Method
507.3 with test conditions.
o Procedure I, Cycle 2 - Procedure 1 simulates natural environmental cycles and is
conducted on test items which are open to a frequently ventilated environment. Cycle 2
sets the temperature at a 24C constant with humidity maintained at 95% minimum. The
Test Duration is 15 Cycles (15 days).
• Cyclic Humidity
o Temperature/Cyclic Humidity Test is 5 days at -10C to 65C at 85% relative humidity
• Thermal Shock
o -40C to 85C (30 minutes at each temp, 10 cycles)
• Shock
o Mechanical shock of a 20G, sawtooth profile, over an 11 msec period. (Three positive
and three negative shocks in each of three mutually perpendicular axes)
o SAEJ1455 shock requirements and those in MIL-STD-810E [11].
• Vibration
o 20 Hz to 2 KHz, 8
G
rms vibration profile in each of three mutually perpendicular axes, 1
hour per axis,
o 10 Hz to 150 HZ, 0.5 g square/Hz vibration profile in each of three mutually
perpendicular axes, 1 hour per axis.
o 10 Hz to 150 HZ, 0.05 g^2/Hz vibration, 16 hours on each of three orthogonal axis
o 5 Hz to 20 Hz , 0.05 g^2/hz, and from 20 to 150 Hz, -3 dB/octave, 1 hour each axes
o Vibration requirements in Orbcomm Rev D spec [10] and MIL-STD-810E [11]
