ISO 4892-2: Xenon-Arc Exposure Method

ISO 4892-2 specifies test conditions replicating weathering effects on plastic materials through the use of moisture and xenon arc light. By using appropriate filters, it is possible to reproduce direct sun exposure or daylight through glass. This method matches the solar spectra responsible for color fading, making it ideal for assessment of aesthetic performance over time.

Understanding the Standard

ISO 4892-2 specifies methods for exposing specimens to xenon-arc light in the presence of moisture to reproduce weathering effects. This includes quartz-jacketed xenon-arc lamps fitted with filters to simulate the relative spectral irradiance of daylight in UV and visible regions.
