The review copy will be edited for publication and may also be revised as appropriate based on any comments received during the public comment period. Therefore, this copy is not suitable for continued utilization and is intended only for comment purposes.

Final publication of the standard may take several months. When it is available, a notice will be published in the official notice section of Journal – American Water Works Association. The standard becomes an effective AWWA standard on the first day of the month following such publication in Journal – American Water Works Association. 

SCOPE
This standard describes the manufacture of concrete pressure pipe, reinforced with a steel cylinder that is helically wrapped with mild steel bar reinforcement, in sizes ranging from 10 in. through 72 in. (250 mm through 1,830 mm), inclusive, and for working pressures up to 400 psi (2,760 kPa). 

MAJOR REVISIONS
Major changes made to the standard in this edition include the following:
1. ASTM C595 type IL cement has been added as a cement type (Sec. 4.4.1.1).
2. The allowable circumferential steel stress used in the design of fittings has been modified (Sec. 4.7.2.1).
