This standard is part of the series on environmental testing for optics and photonics. It specifically specifies the comprehensive environmental test methods for simultaneously exposing optical and photonic instruments and equipment (including related components from other fields) to pollutants and solar radiation. The test aims to evaluate the instrument's tolerance under more severe combined environmental conditions, with a severity level significantly higher than that of single environmental tests. According to the standard method, when conducting such comprehensive tests, a solar radiation simulation test chamber (such as a xenon lamp weathering test chamber) is required to accurately simulate and apply solar radiation conditions. This provides a crucial and unified technical basis for evaluating the environmental reliability of instruments under potential real-world usage conditions.
