APPENDIX D
D.3.6.1 Fifty mile scenario. During the test, operators are to run one 50 mile scenario at
a time in accordance with the mission profile requirements stated below. A mission profile
requirement will consist of the following:
Secondary road....................22.5 miles
Paved road.........................10.5 miles
Combined X Country.............17 miles
D.3.7 Climatological conditions. In order to expose the track test samples to the
maximum "hot" weather conditions, vehicle road testing shall be selected to start no earlier than
1 March and no later than 1 September of the same calendar year.
D.3.8 Pad delivery and storage. Pad samples shall be delivered to the test site by a date
as specified by the Preparing Activity. Adequate time must be allowed for test site personnel to
inspect, mark, and install the hardware so as not to impact the projected test start date. A secured
area must be made available during and after the test for each of the track pad samples. The
samples received will be placed in a shaded area that prevents direct sunlight from shining on the
track pads during storage and assembly operations. The reduction of variables such as solar
heating of the pads in a stack while others are shaded and, therefore, cooler is mandatory. Any
condition that might influence the relative performance of the track pads shall be held as uniform
as possible.
D.3.9 Contractor hardware requirements. For the qualification road test, the contractor
test samples shall consist of 164 complete pad assemblies (to include self-locking nut,
P/N MS51943). In addition, 136 spare pads (with self-locking nut, P/N MS51943) shall be
required.
D.3.10 Initial inspection/preparation for test. The test site shall perform a receiving
inspection of the Bradley series vehicle to be used for the test. The basic test vehicle will be
visually and functionally checked with specific attention given to suspension, electrical systems,
hydraulic systems, and automotive controls and accessories. Any damage or improper operation
will be repaired/corrected to ensure the vehicle will be capable of meeting the test requirements
defined by this appendix.
D.3.10.1 Qualification sample inspection. Contractor supplied track pad qualification
samples will be inspected to ensure no physical damage has occurred in shipment, that the
required number of samples and spares have been provided, and that all components are properly
identified.
