4.4.3.5.2 After three consecutive lots have complied with the
criteria of 4.4.3.5.1, eighty (80) assemblies shall be selected from
each lot for test. The lot shall be rejected if, during the test, a
critical defect occurs or if four (4) or more assemblies exhibit any
of the remaining major defect as listed in Table III. The lot shall
also be rejected if the total of minor and major defects equal five
(5) or more when tested in accordance with 4.5.5. (Destructive test)
NOTE: If sound is used in the measurement of functioning time,
the time required for the sound to travel from the source to the
measuring device must be considered.
4.4.3.6 Chamber qaging (see dwg. 8848486) - Major
defect. This
test shall be performed 100 percent. Any assembly that

have been subjected to adverse conditions, however brief, at any
time since previous tests, the primer lots shall be subjected to and
must satisfactorily pass the check test specified in Section 6 of
the applicable primer specification. The check test shall be
performed by the contractor (see 6.5) prior to assembling the
primers into the simulators.
