Solving customer problems with advanced analysis and "analytical skills"! Introduction to weather resistance testing.
Conducting outdoor exposure tests to determine how long a product can be used is fundamental. However, due to reasons such as the need for long testing times, varying results depending on exposure locations, and differing weather conditions each year, a method using "accelerated weathering tests (weather meters)" has been developed to conduct tests in a shorter time frame. Since Japanese industrial products are used in various countries and regions, it is necessary to understand the extent of product degradation under the weather conditions of the locations where they are used. 【Comparison of Weathering Test Light Sources】 <Xenon Arc Lamp Weathering Test> ■ Wavelength Range: Broad spectrum UV irradiation close to sunlight - A testing method that strongly emphasizes the reproducibility of natural degradation conditions compared to other accelerated weathering tests. <Sunshine Carbon Arc Lamp Weathering Test> ■ Wavelength Range: UV irradiation of 315-400nm, several times that of sunlight - Significantly affects the degradation of organic materials. <Metal Halide Lamp Weathering Test> ■ Wavelength Range: Contains almost no thermal components (infrared), with about 20-30 times the ultraviolet amount of sunlight - Super-accelerated degradation effects on coatings and plastics. *For more details, please download the PDF or feel free to contact us.

basic information
Comparison of Outdoor Exposure and Accelerated Weathering Test Methods ■ The wavelength range that affects the degradation of materials such as paper and resin is 300-400 nm. ■ When tested with a super xenon lamp at 180 W/m² (300-400 nm), the annual exposure amount in Japan is 298.4 MJ/m² (300-400 nm), which means that 460.5 hours corresponds to one year’s worth of degradation. ■ When conducting standard weathering tests, to simulate actual usage conditions, rainfall conditions are reproduced at intervals of 18 minutes every 200 minutes. *For more details, please download the PDF or feel free to contact us.*
