This standard describes 3- to 48-in. (76- to 1,219-mm) gray-iron or ductile-iron fittings to be used with ductile-iron pipe for water, wastewater, and reclaimed water. Requirements for fittings with mechanical joints and flanged joints are listed in Tables 3 through 21 at the end of this standard. This standard may also be used for fittings with push-on joints or such other joints as may be agreed on at the time of purchase.

For the 3- to 24-in. (76- to 610-mm) size range, ductile-iron mechanical-joint fittings and ductile-iron push-on-joint fittings are rated for 350-psi (2,413-kPa) working pressure. Ductile-iron flange-joint fittings are rated for 250-psi (1,724-kPa) working pressure; however, 24-in. (610-mm) and smaller sizes may be rated for 350 psi (2,413 kPa) with the use of special gaskets. Gray-iron fittings having all types of joints described in this standard are rated for 150- or 250-psi (1,034- or 1,724-kPa) working pressures, as shown in the tables.

For the 30- to 48-in. (762- to 1,219-mm) size range, fittings with all types of joints described in this standard are shown in the tables with rated working pressures of 150 or 250 psi (1,034 or 1,724 kPa), depending on the type of iron as shown in the tables.

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.

Purpose

The purpose of this standard is to provide the minimum requirements for ductile-iron and gray-iron fittings, 3 in. through 48 in. (76 mm through 1,219 mm), for water, wastewater, and reclaimed water.

Application

This standard can be referenced in specifications for ductile-iron and gray-iron fittings, 3 in. through 48 in. (76 mm through 1,219 mm), for water. The stipulations of this standard apply when this document has been referenced and then only to ductile-iron and gray-iron fittings, 3 in. through 48 in. (76 mm through 1,219 mm), for water.
