AWWA solicits public comments on all proposed new AWWA Standards, and on all proposed revisions, reaffirmations, or withdrawals of existing AWWA Standards. The referenced standards project is being considered for approval and the publication of this notice begins the 45-day public comment period for AWWA and ANSI. An electronic public review copy of the proposed standard can be obtained for review during the comment period by emailing etssupport@awwa.org. Comments must be submitted in writing to the AWWA contact listed below no later than the last day of the comment period specified herein.

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 Therefore, this copy is not suitable for continued utilization and is intended only for comment purposes.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 steel and stainless-steel tapping sleeves used to provide outlets and branches on existing pipe with or without interruption of service. They are intended for pipe sizes 4 in. (100 mm) through 48 in. (1,200 mm) with branch outlets through 36 in. (900 mm). This standard includes requirements for materials, dimensions, tolerances, finishes, and testing. This standard is not intended to apply to tapping sleeves welded to pipe. Fabricated tapping sleeves are intended for the transmission and distribution of water, reclaimed water, and wastewater, and for use in other water-supply system facilities. For outlets and main sizes greater than those specified, consult the manufacturer.

MAJOR REVISIONS
Major revisions made to the standard in this edition include the following:
1. An advisory statement was added in the Foreword (Sec. II.B) regarding chlorine and chloramine degradation of elastomers.
2. A statement was added in the Foreword (Sec. I.A) to give an operational history and design basis for the use of a flange with an MSS SP-60 recess.
3. Sec. 2 References has been updated.
4. In Sec. 3 Definitions, the definition for rated pressure was deleted and definitions for shop test pressure and working pressure were added. The definition for transient pressure was slightly revised. These changes were made to make the pressure definitions consistent with AWWA Manual M11.
5. The term “rated pressure” was replaced with “working pressure” in Foreword Sec. III.A and III.B and Sec. 4.3.1 to be consistent with industry terminology.
6. Sec. 4.2.3.1 Tapping flanges for steel tapping sleeves, was revised to remove the requirement for the flange class to be specified by the purchaser and added a recommendation that other materials can be specified by the purchaser.
7. Sec. 4.2.3.2 Tapping flanges for stainless-steel tapping sleeves, was revised to remove the requirement for the flange class to be specified by the purchaser. A number of references were also deleted and a reference to AWWA C228 was added.
8. In Sec. 4.2.5 Bolting, the ASTM metric standards which have been withdrawn were deleted and replaced with reference to ISO standards. A requirement for washers was added to meet ASTM F436.
9. In Sec. 4.3.3.1 the withdrawn ASME metric standard was replaced with a reference to ISO 8678 for carriage heads.
10. In Sec. 4.4.2.4 Stainless-steel weldments, a clarification for low-carbon grade stainless-steel was added as less than 0.03% C.
