Product Mode： Fixed mode of products： Test Speed： Number of tests： Equipment size： Description: This device complies with standards such as GB/T16422.3-1997, GJB, ISO, ASTM G154, etc. It simulates damage caused by sunlight, rainwater, and dew, and tests the material by exposing it to controlled high temperature alternating cycles of light and moisture. It uses ultraviolet lamps to simulate the radiation of sunlight, and uses condensed water and water spray to simulate dew and rainwater. This device can withstand laboratory damage such as fading, color changes, loss of luster, powdering, cracking, cracking, wrinkling, blistering, brittleness, reduced strength, and oxidation that may occur in outdoor environments that take months or even years. The test results can be used to select new materials, improve existing materials, or evaluate changes in material formulations. Choose UVB and UVA lamps for the equipment. It can generate stronger shortwave ultraviolet radiation than usual on the Earth's surface, allowing for faster testing results. UVB lamp exposure testing can be useful for quality control applications or for testing extreme durability materials.
