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 Therefore, this copy is not suitable for continued utilization and is intended only for comment purposes.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 polyethylene (PE) pressure pipe and fittings made from materials conforming to standard PE materials designation code PE 4710.

MAJOR REVISIONS
Major changes made to the standard in this edition include the following:
1. Non-PE4710 resins have been removed from the scope (Sec. 1.1) and throughout the standard.
2. The foreword special issues section on Oxidative Resistance was rewritten. (Sec. II.C.)
3. The definitions for design factor, hydrostatic design basis (HDB), standard dimension ration (SDR), and virgin PE compound have been updated. Definitions for PE4710, PE compound, potable water, reclaimed water, safety factor, sample, specimen, and wastewater have been added. (Sec. 3)
4. Addition of chlorine category requirement CC3 for potable water applications in the materials section (4.2.1.2).
5. UV stabilizer information has been updated (4.2.2).
6. Pipe sizes of 5, 7, 13 and 21.5 inches have been removed from Table 3, and DRs 32.5, 26, 19, 15.5, 9.3, and 7.3 were removed from Tables 5, 6, and 7.
7. Tensile tests have been grouped and clarified (4.3.7).
8. Ductility tests have been grouped and clarified (4.3.8).
9. AWWA Basis of Rejection language has been added (5.8).
10. Required markings related to cell class designation and oxidative resistance classification for pipe (6.1.2) and fittings (6.1.3) have been updated. 
11. End caps or other suitable prevention has been added to shipping requirements (6.2).
12. The appendix on surge pressures, fatigue life, and flow capacity has been rewritten (Appendix A).
13. Additional bibliographical sources regarding permeation have been included (Appendix B).
14. Bibliographic sources for additional HDPE pipe information have been added (Appendix C).
