Among the principal concerns relating to the utilization of active solar systems for space or water heating are those regarding durability. One of the. major factors which affect the durability of a solar heating system is the interaction between the heat transfer liquid and its containment system. This interaction may result in changes in the properties of the heat transfer liquid, corrosion of the metallic components of the absorber plate as well as other parts of the containment system, or both. In addition, these phenomena show varying degrees of synergism depending on the compositions of the metal (s) and heat transfer liquid. It is the purpose of this paper to describe a test methodology currently being used to evaluate the responses of simulated metallic containment systems and heat transfer liquids to a variety of operating and stagnation conditions. This is part of a study to assess the validity of a proposed ASTM accelerated simulated service test methodology.
