In this work, a series of long duration accelerated aging tests were used to test a set of different reflector materials, from commercial to experimental and low-cost materials, and by taking the durations to extreme levels never before conducted, assuring the appearance of considerable degradation. The most common degradation parameters were determined and a thorough evaluation of the tests, the parameters and their determination techniques was performed. The copper-accelerated acetic acid salt spray test was confirmed to be the quickest test to provoke degradation in most materials and this way offers the possibility to compare different candidates. Other tests provoke little degradation for most materials even after long durations. The development of corrosion spots is the first parameter to show differences for the materials. The specular reflectance is more sensitive to show degradation than the hemispherical reflecance. An overview table was created which allows to determine minimum test durations to select, depending on the parameter and test to be evaluated.

Currently, there is little research on the impact of scale variation on the thermophysical and phase change characteristics of composite chloride salts, and the underlying mechanisms are not yet clear.
