Plastics — Methods of exposure to laboratory light sources — Part 4: Open-flame carbon-arc lamps
This document specifies methods for exposing specimens to open-flame carbon-arc lamps in the presence of moisture to reproduce the weathering effects that occur when materials are exposed in actual end-use environments to global solar radiation, or to window-glass filtered solar radiation.
The specimens are exposed to filtered open-flame carbon-arc light under controlled environmental conditions (temperature, moisture). Various filters are described.
General guidance is given in ISO 4892-1.
