Accelerated Test Conditions
The main influencing factor of indoor coating aging yellowing is ultraviolet light in the range of light wave 290~400 nm in sunlight, which has strong light energy and has the greatest damaging effect on the coating.
The UV Weathering Tester adopts the test method of ISO 11507: 1997 "Pigments and varnishes - Artificial climate aging of coatings - Exposure to fluorescent ultraviolet light and water" according to the international standard for accelerated UV aging.
