Abstract:
1. An accelerated weathering test apparatus of the type used to concentrate solar radiation upon test specimens including a frame supporting a reflecting solar concentrator disposed in opposition to a target board supported in an air tunnel having a deflector to circulate air across the test specimens mounted on the target board, the accelerated weathering test apparatus comprising: a fixture connected to the target board including a frame spaced from the target board a predetermined distance by a plurality of stand-offs, the fixture having at least one opening defined therein, and a transparent element connected to the frame in alignment with said at least one opening in a covering orientation such that the solar radiation from the reflecting solar concentrator impinges upon the test specimens, wherein the predetermined distance is configured such that the frame functions as an extension of the deflector and an operating temperature of the test specimens is shielded from external influences.
