This standard covers 3-in. through 24-in. (76-mm through 610-mm) and 54-in. through 64-in. (1,400-mm through 1,600-mm) ductile-iron compact fittings to be used with ductile-iron pipe or pipe made of other materials with similar outside diameters for conveying water. For the 3-in. through 24-in. (76-mm through 610-mm) size range, fittings are rated for 350-psi (2,413-kPa) working pressure. For the 54-in. through 64-in. (1,400-mm through 1,600-mm) size range, fittings are rated for 150-psi (1,034-kPa) working pressure. Fittings with mechanical joints are listed in this standard for the 3-in. through 24-in. (76-mm through 610-mm) sizes. The standard also may be used for fittings of these sizes with push-on joints or such other joints as agreed on at the time of purchase. Fittings with push-on joints and flanged joints are listed in this standard for the 54-in. through 64-in. (1,400-mm through 1,600-mm) sizes. Fittings with flange joints are not covered by this standard for sizes 3 in. through 24 in. (76 mm through 610 mm), due to the importance of standardized center-to-flange face dimensions for these sizes already covered in ANSI/AWWA C110/A21.10. Fittings with plain end(s) are listed for bends and reducers of the 3-in. through 24-in. (76-mm through 610-mm) and 54-in. through 64-in. (1,400-mm through 1,600-mm) size ranges and for tees and crosses of the 54-in. through 64-in. (1,400-mm through 1,600-mm) size range. The major revisions in this edition of ANSI/AWWA C153 include the following:
