Plastics. Test method for exposing polyolefins outdoors combining natural weathering and artificial irradiation PAS 015What is ISO TS 21488 about? ISO TS 21488 specifies methods for exposing specimen to alternating outdoor weathering supported with artificial radiation. This method utilizes, as much as possible, the natural outdoor exposure which are then assisted by the artificial radiation during nighttime and in cloudy conditions. ISO TS 21488 is applicable to polyolefin materials as well as to products and portions of products. The artificial and natural outdoor
