UVA UVB Light Fastness UV Aging Test Chamber , UV Accelerated Weathering Tester

ISO ASTM Standard Light Fastness UV Exposure Aging Test Chamber For Environmental Climatic Accelerated Weathering Testing

Description

UV aging test Chamber is designed for evaluating the resistant performance of non-metallic materials, organic materials (plastics, paints, coatings, rubbers, etc.) under the specified conditions such as sunlight, temperature, and other climatic conditions. It creates a man-made testing environment imitating the natural light source such as sunlight and other damages in the nature, such as rain and dew damage, to impose on the materials and to assess the degree of color changing and fading under the accelerated environment conditions. The chamber fully complies with the requirements of Standard GB/T16585-1996, GB14522-93, GB/T16422.3-97, ASTMG53 and etc., provides the best UV sunlight simulation and is easy to use and operate.
