Accelerated Weathering Instrument. A reliable accelerated weathering instrument in a compact design for acceleration of natural weathering. BANDOL WHEEL® 532/I – designed for dry weathering cycles, was developed for quick but natural weathering, similar to outdoor exposure. To complete the weathering cycle, a mask can be added in the equipment which permits the introduction of obscurity phases without switching off the light source. The samples get a nominal UV radiation level corresponding to about “2 suns”. This permits an important acceleration in weathering that, at the same time, still correlates with natural weathering.
