MIL-DTL-8788F
4.5.4 Acceptance of conformance inspection data. Required conformance tests at the bulk hose level
that were already performed at the hose assembly level (hose assembly in accordance with
MIL-DTL-8790) may be waived if documented approval has been obtained from the qualifying activity.
This applies when substantially identical test requirements and test procedures are required for the hose
assembly and with the identical hose fittings that are manufactured and tested in accordance with
MIL-DTL-8789. When conformance inspection data is to be accepted for the hose in accordance with
MIL-DTL-8788, the hose shall be tested at lest once every 36 months, or once every 20,000 feet of hose
produced, whichever occurs first. For the purpose of this specification, 10,000 hose assemblies is
equivalent to 20,000 feet of bulk hose.
4.5.5 Nonconformance.
4.5.5.1 Failures. If a sample fails to pass any sampling and periodic inspection, see table V, the
manufacturer shall immediately notify the qualifying activity and cognizant inspection activity of such
failure. The manufacturer shall take corrective action on the materials or processes or both as
warranted, on all units of product which can be corrected and which were manufactured under
essentially the same conditions, with essentially the same materials and processes, and which are
considered subject to the same failure.
4.5.5.2 Acceptance and shipment. Acceptance and shipment of the product shall be discontinued
until corrective action acceptable to the qualifying activity, has been taken. After the corrective action
has been taken sampling and periodic inspection, see table V, shall be repeated on additional samples.
At the discretion of the qualifying activity this may included all inspections, or the inspection which the
original sample failed. Individual and sampling and periodic inspections, if applicable, may be
reinstituted. However final acceptance of the hose or hose assemblies shall be withheld until the
sampling and periodic inspection has shown that the corrective action was successful.
4.5.6 Additional QPL test and reporting requirements.
4.5.6.1 Retention of qualification. To retain qualification, the contractor shall submit a test report to
the qualifying activity at 12 month intervals. The qualifying activity shall establish the initial reporting date.
Each test report shall consist of a summary of test and inspection results required by this specification
that were performed during the 12 month reporting interval. As a minimum, the test report shall include
the following:
a.
Number of lots produced and tested, including lot and sample sizes for each lot.
b.
Identify which tests were performed.
c.
Quantities passed.
d.
Quantities failed.
e.
All reworked sampling lots shall be accounted for and identified. A summary of corrective
action taken shall be included.
4.5.6.2 Loss of product qualification.
4.5.6.3 Failure to meet test requirements. The manufacturer shall immediately notify the qualifying
activity at any time during the 12-month reporting period when the qualified product fails to meet the
sampling and periodic inspections requirements of this specification. The manufacturer shall identify and
indicate what corrective action will be taken to correct the problem. Failure to take corrective action
acceptable to the qualifying activity may result in removal of the product from the QPL.
4.5.6.4 Failure to submit summary test data report. Failure to submit a test report within 30 days after
the end of the 12 month reporting period may result in loss of qualification for the product.
