This standard is part of a series of environmental tests designed to evaluate the durability of equipment or components under solar radiation conditions, examining the extent to which they are affected by the thermal and photochemical effects of solar radiation. It can be used to detect changes in their electrical, mechanical, or other physical properties. To achieve this purpose, the standard specifies the use of specialized solar radiation simulation test chambers, which are capable of simulating ground-level solar radiation spectra, irradiance (e.g., up to 1120W/m²), and controlling key environmental conditions such as temperature. The standard provides various test procedures, including continuous and periodic illumination, to primarily evaluate the photochemical degradation effects or thermal effects of materials, respectively.
