Abstract: A device for exposing samples to radiation to test their ageing includes a chamber having a sample-holder cage rotating about an axis, and a lamp holder for placing at least one electromagnetic radiation lamp in a fixed position in a central part of the cage and for supplying the lamp with power. An air circulation system provides a swirling air flow about the axis of the cage. The swirling air flow has components that are tangential and/or radial to the periphery of the cage, and an axial component in the central part of the cage. The cage is mounted rotationally on an axially hollowed-out hub so that the air flow is discharged through the hub. Air inlet louvers are positioned on the periphery of the cage and are directed non-radially. The device is designed to operate with the axis of the rotary cage being positioned in a horizontal direction.
