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.

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 Therefore, this copy is not suitable for continued utilization and is intended only for comment purposes.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 3-in. through 64-in. (80-mm through 1,600-mm) flanged ductile-iron pipe with ductile-iron or gray-iron threaded flanges for potable water, wastewater, and reclaimed water service. Flanged pipe and flanges are rated for a maximum working pressure of 250 psi (1,720 kPa). However, 24-in. (600-mm) and smaller flanged joints with ductile-iron flanges may be rated for a maximum working pressure of 350 psi (2,413 kPa).

MAJOR REVISIONS
Major changes made in this revision of ANSI/AWWA C115 are as follows:

  1. Added section on Chlorine and Chlorine Degradation in the Foreword II.D. 
  2. Modified section 4.2.3 Pipe Threads and Table 1 to include Minimum Thread Length and thread taper. 
  3. Modified section 4.3 and Table 2 for Minimum Skirt Length on Table 2 and Table 3 
  4. Removed section 4.4.6 on Finished pipe/flange weight. 
  5. A new Section 4.4.6 on Pipe Wall Thickness was added. 
  6. Modified Section 4.6 Marking to remove requirement for weight marking and to indicate the location of the fabricator’s mark. 
  7. Added requirement in Section A.3 Installation to avoid damage and incompatibility.
