Body of report; and
i.
Conclusions.
3.1. Test and equipment information. This section shall contain:
a. Make, model and serial number of the unit under test, including identification of major
components.
b. Ship name(s) and hull number(s) for which the unit is being acquired.
c. Compartment or on-deck location where the unit will be installed. If identical units by
make and model number will be installed in any one compartment, identify the specific
location in that compartment where the units will be installed.
d. Overall unit dimensions and orientation of machinery and equipment item undergoing
testing.
e. Evaluating activity and test site, including name, phone number and e-mail addresses of
the individuals who performed and supervised the tests.
f. Test date.
g. Specified acceptance criteria, including reference units.
h. Driver unit horsepower.
i. Rated electrical characteristics, including volts, amps, phase.
j. Rated fluid media parameters (e.g., flow rates, temperatures, pressures).
k. Equipment rated operational speeds (e.g., driver and driven unit rpm).
l. Expected equipment primary source excitation frequencies (e.g., rotational
frequencies, gear tooth mesh frequencies, motor slot frequency, cylinder firing
frequencies, vane frequencies, blade frequencies, piston frequencies, turbocharger
frequencies).
m. Resilient mount manufacturer, model number, and date of manufacture.
n. Number of resilient mounts used. A photo shall be included showing each installed
resilient mount.
o. If the use of non-Navy standard resilient mounts has been approved, include the
characteristics including load rating in pounds and resonant frequency of the mounts.
p. Operational load (e.g., full, half) of the machinery and equipment undergoing testing.
q. Operating speeds (rpm) used during test.
r. Throttling conditions, if any, and a description of how throttling conditions are set and
verified.
s. Operating suction and discharge fluid media parameters during test (e.g., flow rates,
pressures, temperatures).
t. Electrical inputs and outputs used during the test.
