C900-89: AWWA Standard for Polyvinyl Chloride (PVC) Pressure Pipe, 4 In. Through 12 In., for Water Distribution (PDF)
SKU: STC_0027649-PDF
This standard pertains to 4-in. through 12-in. PVC pressure pipe made from class 12454-A or class 12454-B material providing a hydrostatic design basis (HDB) of 4000 psi and with cast-iron-pipe-equivalent (CI) outside diameter (OD) dimensions and with wall thicknesses equivalent to a dimension-ratio (DR) series 14, 18, or 25. Design considerations are provided in the appendix to this standard and in PVC Pipe--Design and Installation.
Description
The history of the standard, purpose and application, information to be supplied by the purchaser, major revisions, and AWWA Manual M23 are covered in the foreword. Section 1 discusses scope, definitions, references, and affidavit of compliance. Section 2 on pipe, couplings, and joining materials discusses basic materials, pipe requirements, coupling requirements, performance requirements for elastomeric-gasket joints, permeation, marking requirements, shipping, delivery, and pressure-class ratings for pipe. Section 3 covers inspection and testing by manufacturer including quality-control test requirements, quality-control records and hydrostatic proof-test requirements. Section 4 on plant inspection by purchaser includes production notice, manufacturer's responsibility, inspection limitations, plant access, and inspection aids. The appendix covers AWWA design requirements and criteria for polyvinyl chloride (PVC) pipe for water distribution and includes general requirements, design terminology, internal pressures, external loads, deflection, installation, and failure modes. Major revisions include: provisions for solvent-welded joints throughout the standard were deleted; provisions for iron-pipe-size (IPS) outside diameters throughout the standard were deleted; and references to outside-diameter-to-wall-thickness ratios were changed to DR designations for consistency.
