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 Therefore, this copy is not suitable for continued utilization and is intended only for comment purposes.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 provides formulas to calculate overall dimensions of fittings for steel water transmission and distribution facilities. 

MAJOR REVISIONS
Major revisions made to the standard in this edition include the following:
1. Sec. 4.1.2 was modified to note nominal diameter as the basis for calculating reducer length.
2. Secs. 4.1.7, 4.1.8, and Sec. 4.1.9, and Figures 1E Case I and 1E Case II, and Figure 5, were modified to delineate lateral lower angular deflection limits based on the type of reinforcement being utilized; 45° for laterals utilizing crotch plate reinforcement and 30° for laterals not utilizing crotch plate reinforcement. The changes address potential fabrication/welding difficulties in the acute crotch of the lateral.
3. Sec. 4.1.10, minimum bifurcation angle was increased from 30° to 45°. This increase addresses potential fabrication/welding difficulties in the acute crotch of the bifurcation.
4. Figures 1A through 1E were modified to identify outlets utilizing verbiage consistent with AWWA M11.
5. Figure 2B was modified to reflect the maximum deflection angle of 30°.
