Weather Resistance Test
By changing the conditions of ultraviolet irradiation from carbon arc discharge, as well as the temperature, humidity, and water spray inside the chamber, it is possible to conduct accelerated testing of degradation that occurs due to outdoor use of products, parts, and materials, which takes a long time in nature.
Solving customer problems with advanced analysis and "insight"! 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 approximately 20~30 times the UV amount of sunlight ・Super-accelerated degradation effect on coatings and plastics. *For more details, please download the PDF or feel free to contact us.
