Environmental Aging / Life Cycle

Clark's Environmental Lab can test equipment at different temperature and humidity environments to comply with IEEE 323 or any other commercial/military standards (Methods 501.1, 502.1 and 507.1 of MIL-STD-810 and Method 102A of MIL-STD-202D). Environmental chambers of different sizes, including walk-in rooms, are available to perform test programs. Temperature range of +200°F to -200°F and relative humidity range of 40% to 100% can be maintained.

• 0% to 90% relative humidity, non-condensing

Capabilities

Tempature Range:	-30°F to +177°C
Humidity Range:	20% RH to 95% RH (In the tempature range bounded by an 85°C maximum dry bulb tempature and a 4°C minimum dew point.)
Altitude Simulation Range:	Site to 50,000 Feet
Temperature Control Stability:	+-1°C as measured at the control/measuring sensor after stbilization. Stabilization occurs when the tempature of the chamber wall liner changes less than 2°C per hour.
Chamber Gradient:	Not Applicable
