"An apparatus was designed and built which held two u-bend specimens. When the specimens were exposed to a corrodent, losses in strength were detected as a result of stress corrosion cracking. The apparatus was used to study time to failure of cartridge brass u-bend specimens exposed to ammoniacal copper sulfate solutions which varied in pH. A minimum time to failure, 1.06 hours, was detected at pH 7.2. The maximum time to failure, for the range studied, was 28.36 hours at pH 7.7. No useful data were obtained in the range from pH 6.6 - 6.8. thick, black surface coatings were found to be present on the specimens and these were believed to be responsible for the lack of indicated failure"--Abstract, page ii.
