A.4.5.5
A.4.5.5 Retention of qualification. To retain qualification, the manufacturer shall make available to the qualifying
activity data concerning production of qualified product at 12-month intervals. The qualifying activity shall establish
the initial reporting date. The retention of qualification data shall consist of:
a.
A summary of the results of the tests performed for inspection of product delivery (in-process and group A)
indicating as a minimum the number of lots that have passed and the number of lots that have failed. The
results of tests of all reworked lots shall be identified and accounted for.
b.
A summary of the results of tests performed for periodic conformance inspection (group B) performed and
completed during the 12-month period.
c.
The actual test data for groups A and B shall be supplied to the qualifying activity upon request.
d.
The extent of qualification of base materials specified in A.4.5.4 shall apply.
To retain qualification, the manufacturer shall comply with A.4.5.5.1.
e.
f.
In the event that no production occurred during the 12-month period, the manufacturer shall either certify that
it still has the capabilities and facilities necessary to produce and test the qualified product or requalify.
In the event that no production occurred during the 12-month reporting period, the manufacturer shall either certify to
the qualifying activity that the capability to manufacture and test QPL printed wiring boards still exists and that the
manufacturer wants to remain on the QPL or requalify. If during two consecutive reporting periods there has been no
production, the manufacturer may be required, at the discretion of the qualifying activity, to submit a representative
printed wiring board of each base material type qualified to testing in accordance with the qualification inspection
requirements. Failure to communicate with the qualifying activity within 60 days after the end of the 12-month
reporting period may result in loss of qualification. In addition, the manufacturer shall notify the qualifying activity in
accordance with A.4.7.1.4, at any time during the 12-month reporting period, that the group B inspection data
indicates failure of the qualified product to meet the performance requirements of this appendix.
A.4.5.5.1
A.4.5.5.1 Requalification (see A.6.3.2). Qualifications expire 36 months from the date of qualification. In order to

qualification period.

procedures for the different design standards used for printed boards manufactured (see appendix D).
c.
Procedures detailing the method used to select group B samples (definition of complexity, see A.7.2) and,
when applicable, for providing design details when group B verification testing is preformed externally by a
certified suitable laboratory.
Product assurance procedures that reflect the changes in this specification shall be made available to the qualifying
