APPENDIX A. BACKGROUND/RATIONALE
ANNEX 1. ENVIRONMENTAL TESTS
A.1-3.1.2.1.1 Military Wheeled Vehicle Dynamics (Appendix C, Annex 2, Paragraphs C.2-2.1
and C.2-2.2).
a. Military land transportation as secured cargo on wheeled vehicles consists of both
vibration and shock elements that require individual tests to fully address the environment.
Furthermore, military land transportation may incorporate aspects of both on- and off-road
movement. The vibration element of this environment can be addressed by the profiles in
MIL-STD-810, Method 514 for a `Tactical Wheeled Vehicle' using a duration equivalent to
distances shown in Table A-2. Since a mission profile, incorporating both on- and off-road
movement, was considered during development of the tactical wheeled vehicle vibration spectra
there is no requirement for separate tests to address these two aspects of the environment.
b. Some weapon systems require special military transport vehicles. These vehicles most
likely are not addressed in the Method 514 `Tactical Wheeled Vehicle' vibration test schedule. In
this case tailored test specifications need to be developed based upon measured field data.
c. Restrained cargo shock testing is required to address minor obstacle negotiation for
wheeled vehicles, particularly those travelling in an off-road role. This environment must be
conducted in order to meet the dynamic test requirements, and individual elements cannot be
tailored out. The Restrained Cargo Transport Shock levels in MIL-STD-810, Method 516 are
considered sufficient to satisfy the intent of this test and are specified in Annex C, Table C2-1.
d. These tests should be conducted in the configuration identified in the LCEP for this
mode of transportation. Note that sea launched munitions movement may be limited to short
distances as defined in the LCEP. See Table A-2 for an example of transport distance and test
duration. Tailor the tests accordingly.
A.1-3.1.2.1.2 Two Wheeled Trailer Vibration (Appendix C, Annex 2, Paragraph C.2-2.3).
Transportation of surface and underwater munitions on a two-wheeled trailer is unlikely although
transport of small land based munitions is possible. If two wheeled trailer transport is identified
as part of the LCEP, the environment can be addressed by the vibration profiles in MIL-STD-810,
Method 514 for `Two Wheeled Trailer'.
A.1-3.1.2.1.3 Tracked Vehicle Transportation Vibration (Appendix C, Annex 2, Paragraph C.2-
2.4).
Transportation of sea based munitions on tracked vehicles is unlikely and need not be considered
unless identified as part of the LCEP. Transport of land based munitions by a tracked vehicle is a
possible transport mode. This environment can be addressed by the vibration profiles in MIL-
STD-810, Method 514 and ITOP 01-2-601 using a duration equivalent to the distance specified in
the LCEP. Typically, the shock aspects associated with this environment are addressed by other
tests in the sequence so there is no requirement to address these specifically.
