Abstract
An apparatus for accelerating the weathering effects on test specimens within a test chamber including a calibration-access assembly for replacing test sensors located within the apparatus with reference sensors when the apparatus door is closed. An improved sensor support assembly is also included. The calibration-access assembly from an improved location, facilitating superior irradiance detection. The calibration-access assembly including an aperture defined in the door of the apparatus and a shield connected to the door that is movable to permit or prevent access to sensors when the apparatus door is closed.
