mission lines, dehydrators, coolant lines, piping, and so forth, have been installed in
accordance with plans and specifications; that continuity exists in all interconnections.
b.
That the test equipment listed in Chapter 1 is on board, operating satisfactorily, has been
calibrated and has adequate storage in accordance with NAVSEA ST000-AB-GYD-
010/PEETE.
c.
That the APL is on board, that the Coordinated Shipboard Allowance List (COSAL) includes
the equipment data.
d.
That all field changes, SHIPALTs, and mandatory retrofits have been accomplished.
e.
That all installation and reference standards are entered on the Installation Standards
Summary Sheet.
f.
That all rotating devices are free from obstruction.
g.
That there is access to the equipment for maintenance.
h.
That all pre-energizing servicing procedures, including lubrication have been accomplished.
i.
That it is safe to turn on the equipment.
3.6.9.9.2 Phase 2 - Initial turn-on and preliminary test. Procedures shall be included for
energizing the equipment for the first time. This may be accomplished by reference to the
applicable portions of Chapter 2. Step-by-step procedures shall be included for testing the
equipment electrical supply circuits including distribution panels, switches, breakers, relief valves,
and interlocks. Procedures shall be included for testing piping, electrical cables, wire rope, stays,
for proper installation of transmission lines and waveguides, hangar spacing, torquing of
connectors, pressure testing, flow rates, standing wave ratio and attenuation checks, and so forth.
3.6.9.9.2.1 Phase 3 - Installation verification test. Complete instructions shall be included for
testing the equipment in all modes of operation. Where applicable, refer to the scheduled
performance tests in Chapter 4. Procedures shall cover checking gauges, meters, alarms, and
other sensing devices for proper operation and calibration. The tests shall verify that all inputs are
in tolerance. Where applicable, include voltage standing wave ratio (VSWR) and insertion loss
tests to verify the proper installation of antenna-to-equipment waveguide runs; transducer
impedance and source level checks to verify proper installation of transducers, domes, and cables.
Preliminary setup data shall be included in each procedure. When it is required that an alignment
be accomplished prior to performing a test, the alignment shall be included or referenced in the
procedure.
3.6.9.9.2.2 Test procedure. Testing procedures shall be presented in a logical order as follows:
a. Energize the equipment.
b. Test the first units (normally power supplies) which shall be operating properly. When test
results are within the required tolerance, include reference to the next logical test. Include a
reference to the corrective maintenance or troubleshooting data to be used if test results are
not within tolerances.
3.6.9.9.2.3 Installation standards summary sheet. The installation standards summary sheet shall
provide spaces for recording the results of all installation verification tests and significant
reference standard tests that should be made a matter of record for reference by the technician
