44、 The projectiles shall be forwarded to a Government Proving Ground designated by the Contracting Officer for the ballistic functioning test. 4.3.3 Rejection. See MIL-A-48078 The first article sample shall be rejected if any assembly or projectile fails to comply with any of the examinations or tests

45、 specified in this specification, or any of the requirements of the applicable drawing. In addition, the first article sample shall be rejected if the ballistic test results reveal any one of the defects listed in 4.4.3.9.1. Defects from the round fired at excess pressure shall be recorded for infor

46、mation, but shall not be included for accept/reject purposes unless a hazardous dud condition is detected. Description of test items and procedures are described in paragraphs 6.4 and 4. 5. 8 respectively. In the event of rejection, the Government reserves the right to require the contractor to take

47、 corrective action and submit a new first article quantity. Until the first article quantity is accepted, the contractor is not to proceed with regular production unless otherwise directed by the Contracting Officer. 7 Provided by IHSNot for ResaleNo reproduction or networking permitted without lice
