one bottle of CO2. After a time delay of not more than 11 seconds, the system shall begin
discharging CO2 into the engine compartment and the center of the engine "V". After returning
the handle to its original position, a second actuation shall discharge the remaining two bottles of
CO2. The CO2 meters shall register a peak CO2 concentration of at least 70 percent diminishing
to zero within 1 minute after discharge. Removal and weighing of the CO2 cylinders shall show
a minimum of 10 pounds of CO2 discharged.
4.5.3.12 Electromagnetic characteristics. To determine conformance to 3.4.9.4 and 3.10
through 3.10.4, the production vehicle test shall include electromagnetic interference tests in
accordance with MIL-STD-462. As an aid to determining intra-system compatibility, broadband
conducted emissions on the +28 vdc bus shall be compared to the limits of CE07. Broadband
radiated emission limts shall be measured at a 6.0 +0.1 meter distance from the vehicle.
Radiated susceptibility test RS03 shall be performed using 1.0KHZ sine wave modulation at
50 percent amplitude modulation as well as CW.
4.5.3.13 Vibration and noise level. To determine conformance to 3.11.1 and 3.11.2, the
average of three noise level readings at each octave band shall be determine at each operator
head position under normal operating procedures. The soundlevel meter, microphone-related
equipment, and techniques employed shall be in accordance with MIL-STD-1474. Verify that
noise hazard signs are clearly visible to personnel in all crew stations.
4.5.4 Preparation for delivery inspection. Preparation for delivery inspection shall be
performed on each vehicle that has completed acceptance and control tests per the applicable
requirements of MIL-V-62060. Final equipment and component installation shall also be
inspected and tested, as required, to determine conformance to applicable requirements of this
specification.
5. PREPARATION FOR DELIVERY
5.1 Preparation for delivery and storage shall be in accordance with MIL-V-62060.
6. NOTES
6.1 Intended use. The vehicle is intended for use by the Armed Forces as a combat
vehicle.
6.2 Ordering data. Acquisition documents should specify the following:
a.
Title, number, and date of this specification.
b.
Preproduction sample if required (see 3.1).
c.
Deep water kit installation when required (see 3.6.8.2).
d.
Radio interference if other than specified (see 3.7).
e.
Selection of applicable levels of preservation, packing and packaging
(see 5.1).
6.3 Safety precautions. Caution should be exercised in handling carbon dioxide
fire-extinguisher cylinders. They should not be dropped, permitted to strike each other, or be
handled roughly. Extreme care should be exercised during reinstallation to avoid tripping
fire-extinguisher control system since physical injury is highly probable.
