  • Temperature reduction fixture for accelerated weathering test apparatus
    Patent number: 7174781
    Abstract: An accelerated weathering test apparatus of the type used to concentrate solar radiation upon test specimens including a fixture connected to a target board including a frame spaced from the target board a predetermined distance by a plurality of stand-offs and having at least one opening defined therein and a transparent element connected to the frame in alignment with each at least one opening in a covering orientation such that the solar radiation from a reflecting solar concentrator impinges upon the test specimens. The predetermined distance is configured such that the frame functions as an extension of a deflector and an operating temperature of the test specimens is shielded from external influences.
