MIL-DTL-22354C
4.2.3 Scope of tests. Pre-production tests shall include all tests deemed necessary to determine that the
equipment meets all the requirements of this specification and the contract. Pre-production tests shall include as a
minimum the tests of 4.4.
4.2.4 Pre-production approval. Approval of the pre-production model shall be by the acquiring activity upon
satisfactory completion of all tests. No production equipments shall be delivered prior to the approval of the pre-
production model. Prefabrication of production equipment prior to the approval of the pre-production model is at the
contractor's own risk. The approved pre-production model will be returned to the contractor for his use in the
fabrication and testing of equipment to be submitted for acceptance. The pre-production model shall not be
considered as one of the equipments under the contract; however, it may be reworked by the contractor and
submitted for acceptance as production equipment.
4.3 Acceptance tests. The contractor shall furnish all samples and shall be responsible for accomplishing the
acceptance tests. All inspection and testing shall be under the supervision of the Government Inspector.
Contractors not having testing facilities satisfactory to the acquiring activity shall engage the service of a commercial
testing laboratory acceptable to the acquiring activity. The contractor shall furnish test reports showing quantitative
results for all acceptance tests. Such reports shall be signed by an authorized representative of the contractor or
laboratory, as applicable. Acceptance or approval of material during the course of manufacture shall not be
construed as a guarantee of the acceptance of the finished product. Acceptance tests shall consist of the tests of
4.5 as a minimum.
4.4 Pre-production tests. The pre-production model antenna shall be subjected to the tests in the specification as
follows, and conducted at a laboratory designated by the acquiring activity.
4.4.1 Inclination. The antenna shall be subjected to inclination test limits specified herein. Shipboard equipment
shall be inclined at the rate of 5 to 7 cycles per minute in one phase to angles of 45 degrees on both sides of the
vertical for a minimum period of 30 minutes. During inclination testing, equipment with drawer slides shall be
extended on its slides, so as to verify that the slides have sufficient lateral strength to support equipment in all test
directions. The test shall be repeated with the equipment reoriented 90 degrees to the plane in which it was
originally tested. The equipment shall be energized and fully operating during the test. At the conclusion of the
cyclic tests, the cyclic motion shall be stopped and the inclination adjusted to an angle of 15 degrees. The
equipment shall then be operated for a sufficient period to ensure that the continuous operation can be maintained.
The equipment shall then be rotated through the vertical to 15 degrees in the opposite direction, and the test for
continuous operation repeated. The test shall be repeated with the equipment reoriented 90 degrees to the plane in
which it was originally tested. Equipment intended for submarine installation shall be subjected to the test herein,
except that the maximum angle shall be 60 degrees.
4.4.2 Vibration (shipboard-mounted equipment). Shipboard-mounted antennas shall be subjected to vibration
tests in accordance with type I requirements of MIL-STD-167-1. Equipment shall be operating when tested.
Vibration test levels shall be tailored to the application platform levels. A vibration response investigation shall be
performed. Equipment shall be subjected to endurance testing at fixed frequencies based upon the critical
resonance frequencies determined from the vibration response investigation. When vibration response investigation
does not identify critical frequencies, tests shall be conducted at the maximum vibration frequency. The test duration
at each frequency shall be 2 hours, The vibration frequency range and amplitude shall be as specified in table I.
