3.2.1.6
One Year Warranty Period Testing
The Contractor shall inspect, test, and adjust the cathodic protection
system [quarterly] [semi-annually] [_____] for one year, [4] [2] [ ]
interim inspections total, to ensure its continued conformance with the
criteria outlined below. The performance period for these tests shall
commence upon the completion of all cathodic protection work, including
changes required to correct deficiencies identified during initial testing,
and preliminary acceptance of the cathodic protection system by the
Contracting Officer. Copies of the One Year Warranty Period Cathodic
Protection System Field Test Report, including field data, and certified by
the Contractor's corrosion engineer shall be submitted to the Contracting
Officer, the activity, and the geographic Engineering Field Division
corrosion [protection program manager] [engineer, LANTNAVFACENGCOM Code
404] [protection program manager, LANTNAVFACENGCOM Code 1614C].
3.2.1.7
Final Field Testing
Conduct final field testing of the cathodic protection system utilizing the
same procedures specified under, "Initial Field Testing of the Galvanic
Cathodic Protection Systems". The Contractor shall inspect, test, and
adjust the cathodic protection system after one year of operation to ensure
its continued conformance with the criteria outlined below. The
performance period for these tests shall commence upon preliminary
acceptance for the cathodic protection system by the Contracting Officer.
Copies of the Final Cathodic Protection System Field Test Report, certified
by the Contractor's corrosion engineer shall be submitted to the
Contracting Officer and the geographic Engineering Field Division corrosion
[protection program manager] [engineer, LANTNAVFACENGCOM Code 404]
[protection program manager, LANTNAVFACENGCOM Code 1614C] for approval, and
as an attachment to the operation and maintenance manual in accordance with
Section 01781, "Operation and Maintenance Data".Text
3.2.2
Criteria for Cathodic Protection
Conduct in accordance with [NACE RP0169] [NACE RP0285]. Criteria for
determining the adequacy of protection shall be selected by the corrosion
engineer as applicable:
**************************************************************************
NOTE: The following criteria are applicable only to
iron and steel structures. Refer to NACE RP0169 for
appropriate criteria for other metal structures.
Not all criteria may be readily applicable to the
type of CP system(s) being designed, and the
designer should select only the applicable criteria.
**************************************************************************
a.
A negative voltage of at least 0.85 volt (850 millivolts) as
measured between the structure surface and a saturated copper-
copper sulfate reference electrode contacting the earth
[electrolyte]. Determination of this voltage is to be made with
the protective current applied to the [structure] [tank]
[pipeline] for a minimum of [24] [_____] hours. Voltage drops
must be considered for valid interpretation of this voltage
measurement. The method of voltage drop consideration shall be
identified by the Contractor's corrosion engineer and approved by
the Government corrosion engineer.
