2/ This test to be performed at the conclusion of the holding period.
3/ Reject for continuous arcing.
4/ The true beam position shall fall within a circle of the indicated radius concentric with tube face.
5/
This test shall be performed during the initial production and once each succeeding 12-calendar months in which there is
production. A regular double sampling plan shall be used, with the first sample of three tubes with an acceptance number of zero,
and a second sample of three tubes with a combined acceptance number of one. In the event of failure, the test will be made as a
part of conformance inspection, part 2, code level D, with an acceptance level of 6.5. The regular "12-calendar month" double
sampling plan shall be reinstated after three consecutive samples have been accepted.
