Dielectric isolation shall conform with NACE RP-0286.
4-22.9
Ductile iron piping systems: Conduct an analysis (except for ductile iron piping under
floor in soil) to determine if CP and/or bonded or unbonded coatings are required. Unbonded
coatings are defined in ANSI/AWWA C105/A21.5.
4-22.10
Economic analysis: Conduct an economic analysis to determine if CP and protective
coatings should be provided for gravity sewer lines and the following structures in soil resistivity
conditions above 10,000 Ohm-cm:
4-22.10.1 Potable water lines.
4-22.10.2 Concentric neutral cable.
4-22.10.3 Other structures. Buried and submerged ferrous metallic structures not covered
above.
4-22.11
Contact with concrete. Ferrous metallic piping passing through concrete shall not be
in contact with the concrete.
