Indeed, by combining the effects of those filters with the apparatus conditions, it is possible to simulate the end uses conditions in order to have a better assessment of the performance of the material over time. In fact, by using the appropriate filters, it is possible to reproduce the characteristics of daylight going through a glass window or direct sun exposure. The point of focus of ISO 4892-2 is the characteristic of the light employed and all the conditions that are required to do an in accelerated aging. Even though ISO 4892-3 is very similar to this method, it differs significantly by the fact that it uses UV fluorescent lights as an illuminating source. ISO 4892-2 is a standard that specifies test conditions replicating weathering effects on plastic materials through the use of moisture and xenon arc light.
