a The average inside diameter of circular pipe and pipe to be reformed into pipe-arches shall not vary more than ½ in. (13 mm) from the specified diameter when measured on the inside crest of the corrugations
for diameters through 48 in. (1200 mm) and one percent for diameters greater than 48 in. (1200 mm). In no case shall the difference in diameter of the abutting pipe ends be more than 1/2 in. (13 mm).
b Circular pipe 54 in. (1350 mm) or more in diameter shall be shop elongated. Circular pipe 48 in. (1200 mm) in diameter may be furnished round or shop elongated in accordance with Sec 725.
c Measured on outside at right angle to a line parallel to axis of pipe. The depth of the corrugations shall not underrun that specified by more than 5 percent.
Unless otherwise provided on the plans or in the contract, the minimum thickness listed in Sec 725, for a specified diameter may be furnished.
