Xenon lamp aging test chamber for ISO 4892-2

Plastics accelerated aging standard

AATCC 16.3, AATCC 169, Accelerated Aging, ASTM D2565, Aging chamber testing, ISO 4892-2 ISO 4892-2 describes various methods for describing the effects of aging on plastic parts through the use of UV testing. This specification is equivalent to ASTM G155 and relies on the use of xenon arc sources. As part of its coating testing services, Sonacme offers xenon lamp burn-in test chambers for ISO 4892-2 testing.

ISO 4892-2 is a standard that specifies test conditions for reproducing weathering effects of plastic materials through the use of moisture and xenon arcs. Although ISO 4892-3 is very similar to this method, it differs significantly from this method in that it uses ultraviolet fluorescent lamps as lighting sources. ISO 4892-2 focuses on the characteristics of the light used and all the conditions required to perform accelerated aging. In fact, by using the appropriate filter, it is possible to reproduce the characteristics of daylight passing through a glass window or shining directly at the sun.

By combining the effects of these filters with xenon lamp burn-in test chamber conditions, end-use conditions can be simulated to better assess the long-term performance of the material. Xenon arc lamp exposure is primarily used to assess aesthetics, as the emission spectrum of this light source matches the part of the solar spectrum that causes fading. The main factors for exposure include: type of filter, exposure time, irradiance level, temperature in the cabinet, and relative humidity.
