The work accomplished during this Quarter included the completion of manufacture and testing of the First Article filters. The tests included the 800 hour Radiation Reliability test on two filters, and Fungus Growth and Temperature testing on three filters. No failures were encountered in any of the tests for any of the five First Article filters. The test reports and filters were sent to the Government contracting agency for further examination and approval. Preparations continued for the Pilot Run of filters when approval from the Government is received. The assumed linear mathematical relationship between the calculated Figure of Merit and the observed Angle of Visual Security was found to be satisfactory when the test data from the First Article Filters were added to the graph produced from earlier observations. This relationship will help to determine performance limits and tolerances for filters produced by the approved Manufacturing Process in this program. Author
