Plastics. Test method for exposing polyolefins outdoors combining natural weathering and artificial irradiation Ingestion-build-98192 These are covered by PAS1 Scope This document 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 night time and in cloudy conditions. This document is applicable to polyolefin materials as well as to products and portions of products. The artificial and natural outdoor exposures and
