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 Therefore, this copy is not suitable for continued utilization and is intended only for comment purposes.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 fabricated full-encirclement stainless-steel clamps for use in the repair or tapped service connection of potable water, wastewater, and reclaimed water piping systems. They are intended for nominal diameters 2 in. (50 mm) through 12 in. (300 mm). Full-encirclement repair clamps shall be manufactured completely from stainless steel or a combination of stainless-steel band and cast ductile-iron lug, along with stainless-steel or low-alloy carbon steel bolts and nuts, depending on service requirements and the purchaser’s documents. Tapped service connection outlets may be provided and shall range from ½-in. through 3-in.  (12-mm through 75-mm) sizes.  This standard does not cover stainless-steel tapping saddles, the seal of which is not fully circumferential. Repair clamps for larger than 12-in. (300-mm) nominal pipe diameters are available from various manufacturers but are not covered by this standard.

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. The definition of Actual outside diameter was revised (Sec. 3).
3. In the definitions Nominal pipe size was changed to Nominal diameter to be consistent with other standards (Sec. 3).
4. The definition of Stainless Steel was added (Sec. 3).
5. The word “design” was replaced by “application” for clarification in Section 4.2.
6. Post-weld cleaning requirements were revised (Sec. 4.3.4).
7. A section for “Basis for Rejection” was added to be consistent with other standards (Sec. 5.5).
8. Marking nomenclature was updated to include requirements for inks, crayons, and adhesive labels (Sec 6.1.3 & Sec. 6.1.4).
9. Appendix A was added to provide additional background information on post-weld cleaning of stainless steel.
