Weathering test plastics
Plastics generally age under direct or indirect exposure to light, mostly due to UV radiation. If the exposure to light is accompanied by exposure to moisture, it is not only decisive how strongly the plastics age, but also how the material properties change over a certain period of time. The loss of mechanical properties can be measured. A frequent test method is an accelerated outdoor test according to DIN EN ISO 4892-2. This takes into account solar radiation and alternating dry and wet cycles.
Standards: DIN EN ISO 4892-2, DIN EN ISO 105-B04, DIN EN ISO 105-B06, ASTM D2565, ASTM D7356 / D7356M – 19
