This standard describes Pressure Class 235 (PC235) polyvinyl chloride (PVC) injection-molded fittings with push-on rubber-gasketed joints in nominal sizes 4 in. through 12 in. (100 mm through 300 mm)* for use in water, wastewater, and reclaimed water service. The fittings are for use with PVC and molecularly oriented polyvinyl chloride (PVCO) pressure pipe having an outside diameter conforming to the dimensions of cast-iron pipe and with dimension ratios (DRs) of 18 (Pressure Class 235) or 25 (Pressure Class 165), as described in ANSI/AWWA C900, Polyvinyl Chloride (PVC) Pressure Pipe and Fabricated Fittings, 4 In. Through 60 In. (100 mm Through 1,500 mm), AWWA Manual M23?PVC Pipe?Design and Installation, and ANSI/AWWA C909, Molecularly Oriented Polyvinyl Chloride (PVCO) Pressure Pipe, 4 In. and Larger. This standard can be referenced in specifications for purchasing and receiving injection-molded PVC pressure fittings, 4 in. (100 mm) and larger, for PVC and PVCO pressure-pipe systems. The stipulations of this standard apply when this document has been referenced and then only to injection-molded PVC pressure fittings, 4 in. to 12 in. (100 mm to 300 mm), for PVC and PVCO pressure-pipe systems.
