Method and apparatus for determining the resistance of materials to light and corrosives

摘要

An accelerated weather testing apparatus includes a test chamber, a lamp ( 16 ), a dispenser ( 18, 20 ), and a specimen support ( 14 ). The lamp is capable of generating UV radiation and directing the radiation towards the specimen support. The dispenser connects to an associated liquid source to dispense either water or acid, or both. The specimen support is disposed in the test chamber below the lamp and the dispenser.
