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 Therefore, this copy is not suitable for continued utilization and is intended only for comment purposes.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 electrically butt-joint-welded straight-seam or spiral-seam pipe and seamless pipe, 6 in. (150 mm) in nominal diameter and larger, for the transmission and distribution of potable, raw, and reclaimed water, or wastewater or for use in other water system facilities.

MAJOR REVISIONS
Major revisions made to the standard in this edition include the following:
1. Updated Sec. I.C. Acceptance in the Foreword with the latest Standards Council language reflecting the addition of reference to NSF/ANSI/CAN 372 and NSF/ANSI/CAN 600.
2. In Sec. II.A Advisory Information on Product Application in the Foreword, Item 5 Roundness of Pipe was revised to provide more information on bracing.
3. The scope was updated to include raw and reclaimed water and wastewater since the standard is applicable to these (Sec. 1.1).
4. The definitions for potable, raw, reclaimed water and wastewater were added and the definitions for bevel, check analysis, flame cutting, MT, PT, RT, random lengths, UT, VT were deleted from Sec. 3 Definitions.
5. Updated Sec. 4.1 Permeation and Sec. 4.2. Materials with the latest Standards Council boilerplate language.
6. The information in Sec. 4.6 Requirements for Welding Qualifications was rearranged, combined, and slightly revised for better flow.
7. Figure 2 Repair method by offset value and wall thickness was revised to include coil splice welds.
8. Sec. 4.8.1 Weld-test specimens was renamed and separated into two sections.
9. Sec. 4.9.4.2 on random lengths was deleted.
10. Sec. 4.11.6.4 Testing and certification was revised.
11. Sec. 4.11.6.5 Gasket dimensions and tolerances was revised and updated splice testing.
12. A new Sec. 4.11.5 Ends for field butt joint welding with sub sections 4.11.5.1 Squareness of pipe ends and Sec. 4.11.5.2 End face tolerances was added to update and replace beveled ends section. This separates butt joint end squareness and butt joint face assessment.
13. A new Fig. 9 Field butt joint end tolerance was added.
14. Sec. 4.11.8.2 Diameter was rearranged and revised.
15. In Sec. 5.2.2.1 Nondestructive testing (NDT), Item 6, Hydrostatic testing of specials was clarified to be at a maximum of the design pressure of the special.
16. Sec. 5.2.2.2 NDT qualifications were clarified for specific methods.
