The assembly shall be moved at a speed no greater than 10 feet per minute past the compass for its entire length, rotated 90 degrees in the horizontal position about its longitudinal axis, and moved slowly back past the compass. This procedure shall

47、 be repeated for each 90 degree rotation of the assembly for four full passes. 4.3.3 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 imp

48、erfections 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.

49、The serial numbers shall be in consecutive order beginning with the number O01 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 acti
