(5) Steel sheetpiles (landslide)
(6) Underground compressed gas distribution systems (except oxygen)
(7) Water distribution systems
(8) Concentric neutral cable
(9) Heating (steam or hot water) distribution systems
(10) Other buried/submerged metallic structures not covered above
D. CP surveys and designs must be performed by a registered corrosion
engineer or National Association of Corrosion Engineers (NACE) certified corrosion or
CP specialist with at least five years experience in the type of CP system being
designed. The consultant's qualifications shall be verified.
E.
Designs for CP must comply with the following:
(1) MIL-HDBK 1004/10, Electrical Engineering, Cathodic Protection
(2) CP systems must be designed to provide protective potentials that
meet the requirements of applicable NACE recommended practices (i.e., RP01-69,
RP02-85, RP03-88, etc.)
(3) All CP designs must be based on specific field tests made at the
proposed construction site. Tests would include soil resistivity (Wenner Four Pin
method), water corrosivity (pH), structure-to-electrolyte (S/E), and potential
measurements (on existing structures or test specimens). Results of field testing will be
provided with design submission.
(4) Designs must include test stations, electrolyte access points and/or
reference electrodes required for routine operation, maintenance and potential
surveying of the CP systems.
(5) Specifications will provide procedures for recommended acceptance
testing including static (native) potentials, initial and final system potentials, and
interference tests.
(6) Air Force designs will also comply with the current Air Force CP
Engineering Technical Letter (ETL).
