AWWA C907-12 Injection-Molded Polyvinyl Chloride (PVC) Pressure Fittings, 4 In. Through 12 In. (100 mm Through 300 mm), for Water, Wastewater, and Reclaimed Water Service (PDF)
SKU: STC_0075647-PDF
This standard describes Pressure Class 235 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). 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 (DR) of 18 (Pressure Class 235) or 25 (Pressure Class 165), as described in ANSI/AWWA C900, Standard for Polyvinyl Chloride (PVC) Pressure Pipe and Fabricated Fittings, 4 In. Through 12 In. (100 mm Through 300 mm), for Water Transmission and Distribution, and ANSI/AWWA C909, Molecularly Oriented Polyvinyl Chloride (PVCO) Pressure Pipe, 4 In. Through 24 In. (100 mm Through 600 mm), for Water, Wastewater, and Reclaimed Water Service.
Description
Major changes made to the standard in this revision include the following: the factor of safety was revised from 2.5 to 2.0 to bring ANSI/AWWA C907 in line with industry practices and other PVC pipe standards; the built-in surge allowance was eliminated; the pressure classes were revised from 150 psi (1035 kPa) to 235 psi (1,620 kPa); and, treatment of surge pressures was expanded to include occasional (emergency) surge and recurring (cyclic) surge.
