B137.2-93

1.1 This Standard covers rigid polyvinyl chloride (PVC) injection-moulded fittings intended for use in pressure applications such as water mains, water service piping, process piping, and fire lines. Fittings covered by this Standard are suitable for use with PVC pipes having outside diameter (OD) dimensions of cast iron pipe. Only one pressure rating, 1620 kpA (Class 150), is included that is suitable for use with compatible-OD PVC pipes having a dimension ratio (DR) of 18 or more. The fittings have gasketed joints. Note: If PVC fittings are to be used in other than water applications, the manufacturer should be consulted. 1.2 This standard includes requirements for materials, workmanship, dimensions, marking, long-term performance under sustained hydrostatic pressure, and injection-moulding quality. 1.3 The vaules given in SI (metric) are the standard. The values in parentheses are for information only.
