High-performance materials for outdoor structures related to automobiles and civil engineering! Measuring resistance to environmental factors!
The "Accelerated Weathering Test" is fundamentally based on outdoor exposure; however, since it takes a long time to assess performance, various accelerated tests have been implemented. Our company provides comprehensive support for product development for customers conducting accelerated weathering tests. Please feel free to consult us if you have any requests. 【Representative Testing Equipment】 ■ Sunshine Weather Meter (SWOM) - Capable of dew cycles as a high acceleration method ■ Xenon Weather Meter (XWOM) - Low degradation acceleration but high reproducibility ■ Metering Weather Meter - Utilizes strong ultraviolet light, resulting in exceptionally high acceleration ■ Ultraviolet Fluorescent Lamp Weather Meter - Conducts cycle tests combining irradiation and dark (condensation) *For more details, please download the PDF or feel free to contact us.
