MIL-STD-2105D
determined by the THA. Test a minimum of three items which have undergone testing in accordance with paragraph 5.1.1.
5.1.2.1.1 Vibration orientation. Conduct vibration tests along the appropriate mutually perpendicular axes.
5.1.2.1.2 Vibration schedule. Determine the vibration schedule from the environmental profile of paragraph 4.1.3.
5.1.2.1.3 Changes in vibration schedule. Changes in the selected schedule of vibration levels, frequency ranges, and
time duration of the test can be affected by the program manager
or the procuring activity with the approval of the service
review organization.
5.1.2.1.4 Test temperatures. Conduct vibration tests at low and elevated temperatures or ambient temperature if the anticipated life cycle environment so dictates.
5.1.2.2 Test procedures. Develop test procedures (see paragraph 6.2) that reflect vibration modes and temperatures anticipated in the item's environment. Consider vibration environments as specified in MIL-STD-167 and MIL-STD-810 including one or more of the following.
5.1.2.2.1 Transportation vibration. If the item is always containerized when transported, vibrate the item in the container. Vibrate the item in the normal configuration as shipped. The item may be vibrated in the bare configuration if it can be shown that testing in the bare configuration produces an equivalent environment. If the item is stowed in a ready service configuration, vibrate the item in a fixture and orientation representative of that configuration.
5.1.2.2.2 Aircraft vibration. Vibrate the item in the configuration utilized for aircraft combat carriage.
5.1.2.2.3 Shipboard vibration. Vibrate the item in its shipboard stowage configuration. Should the item be carried on
a launcher or in a ready service configuration, vibrate the item
in a fixture and orientation representative of that
configuration also.
