SECTION 26 05 19.00 28 Page 12
3.3.2.4 Field Testing
3.3.2.4.1 General
After completion of the installation and splicing, and prior to energizing the conductors, perform wire and cable continuity and insulation tests as herein specified before the conductors are energized. Commercially available pre-terminated wire and cable systems are exempt from these tests.
Contractor must provide all necessary test equipment, labor, and personnel to perform the tests, as herein specified.
Isolate completely all wire and cable from all extraneous electrical connections at cable terminations and joints. Feeder breakers, disconnects in combination motor starters, circuit breakers in panel boards, and other disconnecting devices must be used to isolate the circuits under test.
3.3.2.4.2 Insulation-Resistance Test
Perform Insulation-Resistance Tests on each field-installed conductor with respect to ground and adjacent conductors. Applied potential must be 500 volts dc for 300 volt rated cable and 1000 volts dc for 600 volt rated cable. Take readings after 1 minute and until the reading is constant for 15 seconds. Minimum insulation-resistance values must not be less than 25 Megohms for 300 volt rated cable and 100 Megohms for 600 volt rated cable.
For circuits with conductor sizes 8AWG and smaller insulation resistance testing is not required.
3.3.2.4.3 Continuity Test
Perform Continuity Tests to insure correct cable connection (i.e correct phase conductor, grounded conductor, and grounding conductor wiring) end-to end. Any damages to existing or new electrical equipment resulting from contractor mis-wiring will be repaired and re-verified at contractor's expense. All repairs must be approved by the CO prior to acceptance of the repair.
3.3.2.4.4 Phase-Rotation Tests
Conduct Phase-Rotation Tests on all three-phase circuits using a phase-rotation indicating instrument. Perform phase rotation of electrical connections to connected equipment clockwise, facing the source.
3.3.2.4.5 Link Tests
For all Ethernet cable which is not pre-terminated by the manufacturer, perform Category 5e Link Tests in accordance with TIA-568-C.1 and TIA-568-C.2. Tests shall include wire map, length, insertion loss, NEXT, PSNEXT, ELFEXT, PSELFEXT, return loss, propagation delay, and delay skew.
3.3.2.4.6 Acceptance
Final acceptance will depend upon the successful performance of wire and cable under test. Do not energize any conductor until the final test reports are reviewed and approved by the Contracting Officer.
3.3.2.5 Independent Tests
The Government may at any time make visual inspections, continuity or
SECTION 26 05 19.00 28 Page 13 resistance checks, insulation resistance readings, power factor tests, or dc high-potential tests at field test values.
