accelerated aging/weathering

As defined in the SGIA Glossary for the specialty imaging community.

Laboratory test methodology that simulates long term environmental effects, but at the same time intensify and accelerate the destructive action of natural weathering in an attempt to produce changes in the material similar to those observed after continuous outdoor exposure. (Test involves exposure to artificially produced components of natural weather, light, heat, cold, water vapor, and rain which are controlled and repeated in a given cycle).
