installed].
g.
Protected potential measurement tests: With the entire galvanic
protection system put into operation for at least [one week] [24
hours] [_____], measure potentials along the [pipeline [and at all
casings]] [structure] using a portable [copper-copper sulfate]
[silver-silver chloride] [and all permanent] reference electrodes
and a voltmeter having an input impedance of not less than 10
megohm. The locations of these measurements shall be identical to
the locations used for the base potential measurements.
h.
Interference testing: Perform interference testing with respect
to any crossing and nearby foreign pipes in cooperation with the
owner of the foreign pipes. The testing shall verify that the
cathodic protection system does not have a deleterious effect on
the foreign pipelines, and vice versa. Prepare a full report of
the tests giving all details including remedial actions taken or
recommendations to correct noted interference problems.
3.2.1.4
Initial Cathodic Protection System Field Test Report
The contractor shall submit a field test report of the cathodic protection
system. All structure-to-electrolyte measurements, including initial
potentials and anode outputs, shall be recorded on applicable forms.
Identification of test locations, test station and anode test stations
shall coordinate with the as-built drawings and be provided on system
drawings included in the report. The contractor shall locate, correct, and
report to the Contracting Officer any short circuits encountered during the
checkout of the installed cathodic protection system.
**************************************************************************
NOTE: The requirements of paragraph entitled
"Government Field Testing" are required for cathodic
protection projects in the LANTNAVFACENGCOM area.
The designer should verify their applicability to
projects outside the LANTNAVFACENGCOM area with the
appropriate EFD corrosion program manager.
**************************************************************************
3.2.1.5
Government Field Testing
The government corrosion [engineer, LANTNAVFACENGCOM Code 404] [program
manager, LANTNAVFACENGCOM Code 1614C] shall review the Contractor's initial
field testing report. Approximately four weeks after receipt of the
Contractor's initial test report, the system will be tested and inspected
in the Contractor's presence by the government corrosion [engineer,
LANTNAVFACENGCOM Code 404] [program manager, LANTNAVFACENGCOM Code 1614C].
The Contractor shall correct, at his expense, materials and installations
observed by these tests and inspections to not be in conformance with the
plans and specifications. The Contractor shall pay for all retesting done
by the government engineer made necessary by the correction of deficiencies.
**************************************************************************
NOTE: For cathodic protection projects in the
LANTNAVFACENGCOM area, select the appropriate
LANTNAVFACENGCOM options for paragraphs entitled
"One Year Warranty Period Testing" and "Final Field
Testing."
