APPENDIX A
Verification Guidance
Preparation and use of an inspection check sheet, such as a FIR, citing all the accessories,
components, adjustments and connections will provide a documented record and assurance that
proper installation has been accomplished.
3.5 Reliability, availability, maintainability, durability (RAM-D). The RAM-D
requirements shall be demonstrated by operating ______ vehicles, each for _____ kilometers in
accordance with the distance and percent of distance schedule specified in 3.6.1. For RAM-D
calculations, ______kilometers shall equal one operating hour.
Rationale
To provide requirements, and specific tasks to ensure RAM-D requirements during the
development, production and deployment of vehicles.
Guidance
Insert in the first blank space the quantity of vehicles to be tested. In the second blank space
insert the number of kilometers that each vehicle shall be tested and the total amount of
kilometers (accumulated test distance) in the third space.
Lessons Learned
4.5 RAM-D. To determine conformance to the RAM-D, the requirements shall be verified
by reviewing the test data developed during the testing of ______ vehicles at a Government
Proving Ground. The vehicles shall be operated for a distance of ______ kilometers each, for a
total of ______ kilometers. The data collected shall be reviewed, analyzed and computed as
specified in 3.5.1 through 3.5.4, and Appendix B, System Failure Definition/Scoring Criteria
(FD/SC).
Verification Rationale
Reliability data collected during testing will be analyzed and failures scored utilizing the
system FD/SC guidelines (Appendices B and C) and implemented during official scoring
conferences. Scoring conferences will be held during and at the conclusion of initial production
testing with a contractor representative in attendance. In addition aggregation committee
meetings will be held with contractor representation when necessary to purge failures which
have been corrected and verified through testing.
