The purpose of sunshine tests is to determine the ability of equipment and their enclosures to withstand the effects of solar radiation. These tests consist in exposing the equipment to radiation from a light source (most often xenon arc) with or without association with other climatic conditions such as: dry heat, humidity, and spraying. Many polymer, polypropylene or paint materials are very sensitive to the effects of the sun (bleaching, cracking, etc.).
