Plastics — Test method for exposing polyolefins outdoors combining natural weathering and artificial irradiation

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 their practices applicable to this document are described in ISO 4892-1, ISO 4892-3 and ISO 877-1, ISO 877-2 and ISO 877-3, respectively.
