The acceptance level for each test listed under conformance inspection, part 1, shall be 0.65, (see 4/).
2/
This test shall be the first test performed at the conclusion of the holding period.
3/
This test shall be performed during the initial production and once each succeeding 12-calendar month period in which there is
production. An accept on zero defect sampling plan shall be used, with sample of three tubes having an acceptance number of
zero. In the event of failure, the test will be made as a part of conformance inspection, part 2, with an acceptance level of 6.5
(see 4/). The "12-calendar month" sampling plan shall be reinstated after three consecutive samples have been accepted.
4/
This specification sheet uses accept on zero defect sampling plan in accordance with MIL-PRF-1, table III.
