Abstract

An accelerated weathering test apparatus of the type used to concentrate solar radiation upon test specimens including a heating element that transfers energy to the test specimens. A temperature sensor is operatively coupled to one of the test specimens for generating a test signal representative of the operating temperature of the test specimens. A controller for generating a temperature set point is connected to the temperature sensor and responsive to the test signal for selectively controlling a power level applied to the heating element in order to control a rate at which energy is transferred to the test specimens.
