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 Therefore, this copy is not suitable for continued utilization and is intended only for comment purposes.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 pertains to molecularly oriented polyvinyl chloride (PVCO) pressure pipe that is manufactured from starting stock pipe made from ASTM D1784 cell class 12454 material. The starting stock materials are then oriented through circumferential expansion to provide a hydrostatic design basis (HDB) of 7,100 psi (49.0 MPa).

MAJOR REVISIONS
Major changes made to the standard in this edition include the following:
1. Revisions to references to PPI TR-2 and PPI TR-3 which were incorrect in the previous edition.
2. Move color pigment compound requirements from Section 5.1.5 to Section 4.2.
3. Clarifications to material requirements in Sec. 4.2.1.
4. Clarifications to joint requirements in Sec. 4.4.
