Claim:
An accelerated weathering test apparatus comprising a test chamber defined within an enclosure for exposing a specimen to a light source, the accelerated weathering test apparatus further comprising: a door connected to the enclosure that is movable between an open position that permits access to the test chamber and a closed position that prevents access to the test chamber; a sensor-support assembly disposed in the test chamber including a panel and a sensor removably connected to the panel for exposure to the light source; and a calibration-access assembly including an aperture defined in the door and a shield connected to an interior of the door that is movable between a first operative position that prevents access to the panel and a second operative position that permits access to the panel, wherein a reference sensor is removably connected to the panel in place of the sensor when the door is disposed in the closed position and the shield is disposed in the second operative position, wherein the accelerated weathering test apparatus further comprises a specimen mounting apparatus disposed within the test chamber for supporting a specimen holder and the sensor-support assembly further comprises a pair of bars that extend between opposing enclosure sidewalls, wherein the bars are offset such that the panel is connected to and extends between the bars and is discontiguous with the specimen mounting apparatus.
