The standard describes operating procedures for material exposure testing in sunlight through Glass, designed to simulate material degradation caused by sunlight and water. Since changes in environmental parameters such as solar radiation, temperature, Humidity and contaminants have a significant impact on material degradation, the standard recommends the use of control materials with known performance to assess specimen performance. Testing involves the use of two types of exposure cabinets: Type A for passive ventilated and Type B for enclosed black boxes. The standard applies to comparing the effects of different batches of Glass on materials and does not apply to bare metal corrosion testing.
