“Although the laboratory accelerated tests for the determination of the relative value of structural steel paints afford information of some import, there seems to be a general opinion that the best method to follow, if information of a reliable character is to be obtained, is to make actual field exposure tests upon large surfaces. The results of the above described water-pigment tests suggested the erection of a series of steel panels on which to test out the same pigments under practical service conditions...”

“The three types of metal selected for the test were rolled into billets, the middle of which were selected, and worked up into plates 24 inches wide, 36 inches wide, and 1.8 inch in diameter — approximately 11 gauge...”
