List of methods to be used to protect against electrolytic corrosion of dissimilar metals in
intimate contact in accordance with MIL-STD-889.
f.
Test report for each component covered by a document listed in the DODISS.
Acceptance testing. Acceptance testing shall be classified as follows:
4.4
Individual testing (see 4.4.1).
a.
b.
Random sample testing (see 4.4.2).
4.4.1
Individual testing. Each vehicle shall be subjected to the tests specified in 4.5.1, 4.5.2 and 4.5.3.
4.4.2
Random Sample Test. Any time chosen by the Air Force during the production of vehicles to
meet the total contractual requirement, a production line vehicle may be identified for testing. This test
shall incorporate all tests required in Section 4.5, except 4.5.8, 4.5.9, and Air Transportability
Certification, and be in accordance with the previously approved test procedures.
4.4.2.1 Rejection and retest. When a vehicle fails to meet the requirements of this purchase
description, vehicles to be delivered pursuant to the contract may not be accepted until the cause of the
failure is determined, corrective action is taken by the contractor, and the part that failed is successfully
retested to assure compliance with this specification. Tests not involving the failed part may be continued
pending the investigation of a test failure,
4.5
T e s t met hods.
4.5.1
Examinat ion of product . The vehicle shall be inspected to determine compliance with the
requirements specified herein. Particular attention shall be given to materials, workmanship,
dimensions, surface finishes, protective coatings and their application, welding and riveting, and
markings. For the first article and random sample vehicles, this examination shall be accomplished by
use of a checklist which lists each requirement not validated by a test and the results of the examination.
4.5.2
Lub rication Inspect ion. Observe the lubrication of every fitting on the vehicle to determine
compliance with:
a.
Lubrication by standard military lubricants.
All fittings accessible.
b.
c.
Fittings is vulnerable positions are protected by recessing or bossing.
4.5.3
Draw Bar Pull. The vehicle shall be tested to show conformance with 3.2.1j. The test shall only
be conducted in an environment where the dry barometer pressure is between 28 to 30 in. Hg and ambient
air temperature is between 60 to 110 F. Subsequent tractors shall be tested for static drawbar pull of 11,000
pounds minimum in forward and reverse gears. In each case, diesel fuel conforming to MIL-T-83133
must be used.
Torque Converter Test. Immediately following the test in 4.5.3, the tractor shall be stopped by
4.5.4
application of the service brakes and held stationary by the brakes while the transmission is in the lowest
gear. The engine shall be run at 90% of torque converter stall speed for one minute. The transmission oil
temperature shall not exceed 230.
4.5.5
Endurance Test. The tractor shall be driven through continuous sharp "s" curves in four wheel
drive coordinated steer for a distance of 5 miles on the odometer, and shall be accelerated through gears to
15 MPH, stopped, and backed 15 feet, in cycles for 8 additional miles on the odometer. This test shall be
repeated for four wheel drive, two wheel steer.
