Abstract

An accelerated weathering test apparatus for concentrating solar radiation upon at least one test specimen including a target board, a reflector device, an air circulation device, a feedback device, an input device and a controller. Ambient air is circulated over the target board to cool the test specimens. The controller continuously sets a dynamic set point based on the reference signal from the input device which is representative of a complex temperature cycle of a material end-use application and adjusts the rate of air circulation based on a test signal from the feedback device.
