This part of IEC 60068-2 specifies the methods for testing equipment or components under
simulated solar radiation conditions.
This document is applicable to the equipment and components at the surface of the earth.
The purpose of testing is to investigate to what extent the equipment or components are
affected by simulated solar radiation in the presence of moisture to reproduce the weathering
effects (temperature, humidity and/or wetting) that occur when they are exposed in actual
end-use environments to daylight or to daylight filtered through window glass. This document
specifies two test methods, test method Sa: thermal effect test, and test method Sb:
weathering test.
