b.
A summary of the results of tests performed for periodic inspection, including the
number and mode of failures. The summary shall include results of all periodic in-
spection tests performed and completed during the 3 year period. If the summary
of the test results indicates nonconformance with specification requirements, and
corrective action acceptable to the qualifying activity has not been taken, action may
be taken to remove the failing product from the qualified products list (QPL).
Failure to submit the report within 30 days after the end of each 3 year period may result in loss
of qualification for the product. In addition to the periodic submission of inspection data, the
contractor shall immediately notify the qualifying activity at any time during the 3 year period that
the inspection data indicates failure of the qualified product to meet the requirements of this
specification. In the event that no production occurred during the reporting period, a report shall
be submitted certifying that the company still has the capabilities and facilities necessary to produce
the item. If during two consecutive reporting periods there has been no production, the contractor
may be required, at the discretion of the qualifying activity, to submit his other qualified products
to testing in accordance with the qualification inspection requirements and provide the reason for
no production.
4.4.1 Quality conformance inspection. Quality conformance inspection shall be performed to
ascertain that the production items offered conform to the construction which was approved as a
result of qualification testing and examination, and the production items offered comply with the
requirements set forth in the contract or order (see 6.3).
4.4.2 Sampling. All valves of the same type, class, and size presented for delivery at one
time shall be considered a lot for purposes of quality conformance inspection. A random sample
of valves shall be selected from each lot for examination and testing as specified in table III. For
lot sizes less than nine, 100 percent inspection shall be required.
4.5 Visual and dimensional examination. Each of the sample valves shall be examined to
determine conformance to the requirements specified herein as to material, workmanship,
dimensions, and other requirements not involving tests. Valves containing one or more visual or
dimensional defects shall be rejected.
4.6 Test procedures. Test procedures shall be as specified in 4.6.1 through 4.6.7.
4.6.1 Shock test. High impact shock tests shall be conducted in accordance with MIL-S-901
for grade A, class I equipment. The valve shall be considered acceptable with respect to the high
impact shock requirement if the following conditions have been met:
a.
No breakage of any part has occurred. Examination reveals no cracks or signs of
weakness that could result in failure if operated.
b.
The valve performs and continues to perform as specified without maintenance or
significant adjustment.
c.
There has been no dislocation of valve components that could render the valve unsafe
for continued service.
