**************************************************************************
NOTE: Additional testing may be required, based
upon the specific project or design. All tests
listed below may not be required. Designer should
consider the project requirements for selection of
test procedures.

3.2.1
Testing
3.2.1.1
Destructive Testing
Contractor shall perform the tests in the presence of the Contracting
Officer. Contractor shall include the cost of an additional anode [of each
different type] with the longest lead wire for the destructive test in his
bid. One completed [prepackaged] anode of each type with lead wires shall
be chosen at random for destructive testing and shall be submitted to a
static pull test. Anode lead wire connections of anodes shall have
sufficient strength to withstand a minimum tensile load of [1335] [_____] N
[300] [_____] pounds. [The anode shall also be cut into sections and/or
broken with a sledge hammer to verify conformance with this specification.
Such items as anode-to-wire connection, complete encapsulation of the wire
connector, and wire to anode electrical resistance shall be checked.]
[Failure of the test anode to conform to this specification can be cause
for rejecting all anodes from the same lot as the test anode. The
contractor shall mark all rejected anodes on the ends with a 150 mm 6 inches
high "X" using yellow spray paint. Failed anodes shall be removed from
the job site by the end of the day. The contractor shall replace any
rejected anodes at his expense. The destructive testing provision shall
also apply to replacement anodes as well.]
3.2.1.2
Wire for Power Service
Test wire for power service at 600 volts or less to determine that the
wiring system and equipment are free from short circuits and grounds [by a
minimum of two megohms]. Perform the test with a megohm meter having a
500-volt rating.
3.2.1.3
Initial Cathodic Protection System Field Testing
The systems shall be tested and inspected by the Contractor's corrosion
engineer in the presence of the Contracting Officer's corrosion protection
engineer or an approved representative. Record test data, including date,
time, and locations of testing and submit report to the Contracting
Officer. Contractor shall correct, at his expense, all deficiencies in the
materials and installation observed by these tests and inspections.
Contractor shall pay for retests made necessary by the corrections.
Testing shall include the following measurements:
a.
Base potential tests: At least [one week] [24 hours] [_____] after
[backfilling of the pipe] [installation of the structure to be
protected] [initial operation of structures containing fluids]
[_____] , but before energizing of the cathodic protection system,
measure the base (native) [structure-to-electrolyte]
[pipe-to-soil] potentials of the [pipe [and the casings]]
[structure]. Perform measurements at anode junction boxes, test
stations and other locations suitable for test purposes (such as
service risers or valves) at intervals not exceeding [30] [122]
[_____] meters [100] [400] [_____] feet with readings at each end
