MIL-T-45499C
moved slowly back past the compass. This procedure shall be repeated for each 90 degree rotation of the
assembly for four full passes.
4.3.4 Radiographic examination. All assembled thrusters shall be radiographically examined in
accordance with MIL-STD-453, with the exception that an thruster assembly will be used for the penetrameter.
Any observable imperfections in components or assembly shall be cause for rejection. The thrusters shall be
positioned for the most revealing exposure, with the long axis of each assembly perpendicular to the rays of
the X-ray machine. All thrusters shall be identified with serial numbers prior to X-ray examination. The serial
numbers shall be in consecutive order beginning with the number 001 in each production lot. Any missing
numbers are to be identified on the X-rays. The thrusters shall be arranged on trays or boards in consecutive
numerical order, and each radiograph shall carry a permanent identification of the units displayed thereon.
The radiographic plate identification shall include item nomenclature, the complete lot number, the span of
serial numbers displayed, and the contract number. The radiographs of the entire production lot shall
accompany the ballistic sample to the activity conducting the production lot acceptance test. Defective
thrusters found during X-ray review are to be marked on the X-ray prior to shipment and those defective items
shall be removed from the production lot. Film interpretation of the radiographs shall verify the presence and
correct positioning of the following parts:

4.3.5 Functional.
4.3.5.1 Ballistics. The test sample shall be rigidly supported so that the entire thrust is borne by the
thruster mounting points. The samples shall be tested within 10 minutes after removal from the temperature
conditioning chamber. When this time limit is exceeded, the sample units shall be reconditioned at the
original temperatures.
4.3.5.2 Temperature conditioning. Each assembled thruster shall be conditioned for not less than 4
hours nor greater than 24 hours. When reconditioning thrusters at ·65·F, all condensation shall be removed
from the exterior surfaces before returning the thruster to the conditioning chamber.
4.4 Inspection of packaging. The sampling and inspection of the packaging, packing, and container
marking shall be in accordance with section 5.
