4.2.1 Initial production conditions. Unless otherwise specified (see 6.2), two tube
assemblies from the first 100 tube assemblies produced shall be selected for initial production
inspection. This inspection shall include the examinations of 4.4 (see Table IV and the tests of
Table V).
4.3 Conformance inspection. Conformance inspection shall include the examinations of
4.4 and the tests of 4.5 and 4.6.
4.4 Examination.
4.4.1 Sampling. Samples from an inspection lot for conformance inspection shall be
selected in accordance with ANSI/ASQ Z1.4. Each sample selected shall be inspected as
specified herein for the defects listed in Table IV. Conformance to a lot shall be accepted when
zero (0) defects are found and rejected when one (1) or more defects are found.
4.5 Acceptance tests (100 percent). Each tube assembly shall be subjected to the tests
specified in Table V. Failure of any test shall be cause for rejection.
4.6 Control tests. The control tests shall be conducted on one tube assembly from each
lot of 50 units consecutively produced except that not more than one test shall be performed in a
