The weather resistance of 192 porcelain enameled panels representing 14 enamel types was evaluated after being exposed for 30 years at Washington, D.C.A direct correlation was found between the acid resistance and weather resistance of the enamels tested.The porcelain enamel protected the base metal from corrosion if the initial coverage was complete.Similar evaluations and findings were made on 58 panels representing 13 enamel types that were added to this test in 1947.(Author).
