A bstract Twenty‐one enameled specimens were exposed for approximately tea months in an industrial area arid were graded visually by ten observers for weather resistance based on appearance change as compared with an unexposed standard. Weight‐loss data were obtained on exposure to boiling solutions of (1) distilled water, (2) 6% citric acid, and (3) 5% sodium pyrophosphate. Acid‐resistance data were obtained by employing the Porcelain Enamel Institute research test. These data were correlated with the weather‐resistance gradings. Loss of weight on exposure to boiling 6%; citric acid appeared to give the best indication of weather resistance.
