13、and 60 frames per second. Ik = 500 A dc. 3/ This test shall be performed during the initial production and once each succeeding 12-calendar months in which there is production. An accept on zero defect sampling plan shall be used, with sample of three tubes with an acceptance number of zero. In the
14、event of failure, the test will be made as a part of conformance inspection, part 2, with an acceptance level of 6.5 (see 5/). The regular “12-calendar month“ sampling plan shall be reinstated after three consecutive samples have been accepted. 4/ First article inspection shall consist of performing
15、 all tests listed in this tube specification sheet. The sample size and allowable defects shall be in accordance with MIL-PRF-1, qualification, samples, and acceptance criteria. Three copies of the test report (see MIL-HDBK-831) shall be forwarded to the purchasing activity for evaluation by the pre
16、paring activity. Invitation for bids should provide that the preparing activity reserves the right to waive the requirements for first article samples as to those bidders offering a product which has been previously acquired or tested by the Government, and that bidders offering such products who wi
17、sh to rely on such production or test, must furnish evidence with the bid that prior Government approval is presently appropriate for the pending acquisition. 5/ This specifiction sheet uses accept on zero defect sampling in accordance with MIL-PRF-1, table III.
