System: PVC SDR 35 Gravity Sewer Pipe
Scope: ThisspecicationcoversPVCStandardDimensionRatio(SDR)35PSMpipeforgravitysewerandsurface
water applications with a pipe stiffness of 46. This product is intended for gravity applications where the
operating temperature will not exceed 140°F.
Specification: Pipe shall be manufactured from virgin rigid PVC (polyvinyl chloride) vinyl compounds with a cell class
of12364asidentiedinASTMD1784.Therequirementsofthisspecicationareintendedtoprovide
pipe suitable for non-pressure drainage and surface water.
