The GJB 150.7-1986 standard specifies the test method for military equipment under solar radiation, aiming to evaluate the ability of equipment to face the thermal and photochemical effects of solar radiation in an unsheltered outdoor environment. The standard provides the basis for the development of technical conditions and product standards for military equipment. Through this test, the tolerance and Reliability of equipment under long-term exposure to sunlight can be determined. Note that this standard may have updated versions. It is recommended to consult the latest relevant literature to ensure that the standard version used is the latest.
