Product designers and manufacturers must always guarantee the life of the product.
Market surveys and outdoor exposure tests have been carried out as means to know the lifespan, and actual weather resistance deterioration is confirmed. We also conduct an accelerated weather resistance test in order to know the product lifetime earlier, and compared with results with outdoor exposure tests to predict lifespan. Following this process, measurement examples of outdoor exposure test methods with different atmospheric environmental factors using painted steel plates and outdoor exposure test results will be introduced. We also describe the characteristics of various light sources used for accelerated weathering test and the accelerated weathering resistance test results. There are differences in weather resistance depending on environment, light source, and test method.
