4.2.1 Regulatory requirement. Te pipe and fttings intended for potable water applications shall comply with all applicable requirements of NSF/ANSI 61. Materials used to manufacture potable water pipes shall comply with the require- ments of the Safe Drinking Water Act. In addition, all materials shall comply with other federal regulations for potable water, wastewater, and reclaimed water systems as applicable.
4.2.2 Pipes and fabricated fttings. PVC pipes and fabricated fttings shall be made from virgin PVC resin that has been compounded to provide physical and chemical properties that equal or exceed cell class 12454 as defned in ASTM D1784. Pipe and fttings compounds shall also qualify for a minimum HDB of 4,000 psi (27.58 MPa) at 73.4°F (23°C) in accordance with the requirements of ASTM D2837* or PPI TR-2 or PPI TR-3.
4.2.3 Rework materials. Clean rework materials derived from a manu- facturer’s own pipe or ftting product may be used by the same manufacturer for similar purposes provided that (1) the cell classifcation of the rework material is identical to the material to which it will be added; and (2) the rework material complies with applicable requirements of Sec. 4.2 of this standard.
4.2.4 Certifcation for potable water service. PVC compounds and prod- ucts to be used for potable water shall be certifed by an accredited testing agency for compliance with NSF/ANSI 61.
4.2.5 Gaskets and lubricants. Gaskets and lubricants intended for use with PVC pipe and fabricated fttings shall be made from materials that are compatible with the pipe and with each other when used together. Each gasket-seal bell end of every pipe, ftting, and coupling shall include an elastomeric gasket. Elastomeric gaskets shall meet the requirements of ASTM F477 for high-head (50 ft of head or higher) applications. Gaskets and lubricants intended for use with potable water shall be certifed by an accredited testing agency for compliance with NSF/ANSI 61.
4.2.6 Fabricated ftting overwrap reinforcement. Optional reinforcement, either PVC or non-PVC, may be applied by the fabricated fttings manufacturer to meet the requirements of this standard.AWWA C900-16 pdf download.
