Weathering Test Chambers
Accelerated Weathering Test Chambers are essential laboratory instruments designed to simulate and intensify the damaging effects of outdoor environmental conditions on materials in a controlled and reproducible manner. Both Xenon Arc Test Chambers (governed by ASTM G155) and UV Test Chambers (governed by ASTM G154) fall under this critical category, serving to predict the long-term performance and durability of materials such as coatings, plastics, textiles, automotive components, and industrial products.
While employing different light sources and methodologies, these chambers share the core objective of accelerated weathering. They replicate key environmental stressors including light (spectral distribution), temperature, and moisture to induce and observe degradation mechanisms like color fading, chalking, cracking, gloss loss, and embrittlement within days or weeks—a process that might take months or years in real-world exposure.
