A salt/sulfur dioxide test was chosen as the most appropriate test for evaluating external corrosion of automotive evaporators based on condensate analysis, ecological data, and analysis of units retrieved from the field. The test generates a corrosion attack mode, similar to the field, using conditions that simulate field conditions. The test is able to discriminate between various alloys and processing conditions in the laboratory. The laboratory results compare very well with a controlled field test that is being conducted on worst-case applications. Such data will be utilized in the future to develop a correlation between laboratory and field results to be able to predict field corrosion durability of evaporators as well as to assess the influence of material and process changes on field performance.
