This test to be performed at the conclusion of the holding period. 5. This test applies for flexible leads as well as for rigid leads. 6. The tube shall ha
14、ve reached the end of its life with regard to regulation (1) when that regulation first exceeds the value of 4.0 volts. 7. 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
15、 be used, with a sample of three tubes with an acceptance number of zero. In the event of failure, the test will be made as a part of conformance inspection, part 3, with an acceptance level of 6.5 (see note 9). The regular “12-calender month” sampling plan shall be reinstated after three consecutiv
16、e samples have been accepted. 8. Test to be conducted with the tube under test enclosed in a light tight enclosure composed of a non-conducting material. Measurements to be performed after the test specimen is held in the enclosure for 24 hours. The tube shall fire within 15 seconds. 9. This specifi
