The weight distribution of the vehicle in any loading condition shall not
be unbalanced or improperly distributed. The difference in load between the left and right wheels of any
axle shall not exceed 2.5 percent of the total load on the axle.
The vehicle shall not lean to either side more than one percent of the body width, in
either the fully loaded or the unloaded condition, Body lean measurements shall be made at the outermost
portion of the vehicle (excluding mirrors, mirror support brackets, lights or asymmetrical shapes)
directly above each axle; the difference in body height at each axle shall not exceed one percent of the body
width at that location.
Electromagnetic interference (EMI).
Electromagnetic interference suppression.
The vehicle shall be equipped for the suppression
of electromagnetic interference in accordance with Part 8 (Group I) of MIL-STD-461B as modified below.
As a minimum, these bandwidths listed below shall be used in the appropriate frequency band of the
measurement receiver for UM03 testing.
1 KHz, plus or minus 10 percent
150 KHz- 1MHz
10 KHz, plus or minus 10 percent
1 MHz -30 MHz
100 KHz, plus or minus 10 percent
30 MHz- 1 GHz
The limits for UM03 (Figure 8-1) shall be relaxed by 20dB.
The vehicle shall not exhibit any malfunction, degradation of
performance, or deviation from specified indications beyond the tolerances indicated in the individual
equipment or subsystem specification when subjected to the following radiated electric fields (E) in
accordance with MIL-STD-461B, Part 2, paragraph 19.RS03.
FREQU ENCY RANGE
2MHz to l GHz
The maximum sound level produced by the vehicle shall not exceed
126.96.36.199 Exterior sound level.
83dBA when measured in accordance with SAE J366b. An additional 2dBA allowance shall be permitted
for production units to provide for variation in test site, temperature gradients, test equipment and
inherent differences in nominally identical vehicles.
188.8.131.52 Cab interior sound level. The maximum sound level in the cab interior shall not exceed the
SAE recommended design criteria for new vehicles when measured in accordance with SAE J336A.
The tractor shall be air transportable in accordance with MIL-STD-1791
in types C-130, C-141 and C-5 Aircraft. Removal of beacon light only shall be permitted, if necessary, to
provide the required height for air transport.
184.108.40.206 Tiedowns. The vehicle shall be equipped with sufficient tiedown points so located that it can be
restrained in all directions during air transport, The attachment points shall be designed for use with
attachment in the aircraft as described in MIL-STD-1791. Sufficient clearance shall be maintained
around all attachment points to allow for restraining chains without interference from any other
