This standard describes 3-in. through 64-in. (76-mm through 1,600-mm) ductile-iron pipe, centrifugally cast, for water, with push-on joints or mechanical joints. Requirements for pipe according to this standard are discussed in the text and are shown in Tables 1 through 7 and Figures 1, 2, and 3. This standard may be used for pipe with other types of joints as may be agreed on at the time of purchase. Major revisions made to the standard in this edition include the following: the format has been changed to AWWA standard style; the acceptance clause (Sec. I.C) has been revised to approved wording; definitions for bell, socket, spigot, accessory, restrained joint, and lot were added; and, defective specimens and retests (Sec. 5.6) were clarified.
