This standard describes 3-in. through 64-in. (80-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 potable water, wastewater, and reclaimed water. Minimum working pressures by size range are as follows: 3 in. through 24 in. (80 mm through 600 mm): 350 psi (2,413 kPa); 30 in. through 48 in. (750 mm through 1,200 mm): 250 psi (1,724 kPa); and 54 in. through 64 in. (1,400 mm through 1,600 mm): 150 psi (1,034 kPa). Fittings are adequate for the rated working pressure plus a surge allowance of 100 psi or a surge allowance of half the rated working pressure, whichever is less.

Fittings with mechanical joints are listed in this standard for the 3-in. through 64-in. (80-mm through 1,600-mm) sizes. The standard also may be used for fittings of these sizes with push-on joints or 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 discussed in this standard for sizes 3 in. through 48 in. (80 mm through 1,200 mm) because of the importance of standardized center-to-flange face dimensions for these sizes already described in ANSI*/AWWA C110/A21.10.

Fittings with plain ends are listed for bends and reducers of the 3-in. through 64-in. (80-mm through 1,600-mm) size range and for tees and crosses of the 54-in. through 64-in. (1,400-mm through 1,600-mm) size range.

Purpose

The purpose of this standard is to provide the minimum requirements for ductile-iron compact fittings, 3 in. through 64 in. (80 mm through 1,600 mm), for potable water, wastewater, and reclaimed water service.

* Metric conversions given in this standard are direct conversions of US customary units and are not those specified in International Organization for Standardization (ISO) standards.
