Abstract
An accelerated weathering test apparatus including a target board operatively coupled to a reflector device. The target board is configured to support at least one test specimen for exposure to concentrated solar radiation. The reflector device is configured to reflect and concentrate solar radiation onto the at least one test specimen. The reflector device includes a bed and a plurality of mirrors. Each mirror is disposed on the bed in one of a first operative position, where solar radiation is reflected on the at least one test specimen, and a second operative position, where no solar radiation is reflected on the at least one test specimen. One of the irradiance incident on the at least one test specimen from the reflector device and the temperature of the at least one test specimen is adjustable by movement of selected mirrors from the first operative position to the second operative position in response to an input in order to control one of a temperature of the at least one test specimen or the irradiance.
