4. QUALITY ASSURANCE PROVSIONS.
4.1 Responsibility for inspection. Unless otherwise specified in the contractor purchase order (see 6.2.1), the
contractor is responsible for the performance of all inspection requirements as specified herein. Except as otherwise
specified in the contractor purchase order (see 6.2.1), the contractor may use his own or any other facilities suitable
for the performance of the inspection requirements specified herein, unless disapproved by the Government. The
Government reserves the right to perform any of the inspection= forth in the specifications where such inspections
are deemed necessary to assure supplies and services conform to prescribed requirements.
4.1.1 Responsibility for compliance. All items must meet all requirements of sections 3 and 5. The inspection
set forth in this specification shall become a part of the contractor's overall inspection system or quality program.
The absence of any inspection requirements in the specification shall not relieve the contractor of the responsibility
of assuring that all products or supplies submitted to the Government for acceptance comply with all requirements
of the contract. Sampling in quality conformance does not authorize submission of known defective material, either
indicated or actual, nor does it commit the Government to acceptance of defective material.
4.2 Classification of inspections. The inspection requirements specified herein are classified as follows:
a. First article inspection (see 4.4)
b. Quality conformance inspection (see 4.5).
4.3 Inspection conditions Unless otherwise specified (see 6.2.1), inspection conditions shall be as specified
in the applicable test method (see 4.5.3).
4.4 First article inspection. First article inspection shall be peformed by the contractor, after award of contract
and prior to production, at a location acceptable to the Government. First article inspection shall be performed
on a sample assembly which has been produced with equipment and procedures normally used in production.
4.4.1 Sampling. The first article sample shall be subjected to all the tests of 4.5.3 The sample shall be a first
article assembly submitted by the contractor prior to the initiation of production.
4.4.2 Failure. Failure of a first article slip ring assembly to comply with any of these test requirements shall
result in withholding of first article approval.
4.5 Quality conformance inspection. All quality conformance test samples shall be treated as first article
samples (see. 6.3). Quality conformance inspection shall consist of the tests specified in 4.5.3.
4.5.1 Sample size. The tests specified in 4.5.3 shall be performed throughout production on 1 unit randomly
selected from each group of 10 assemblies submitted for Government acceptance Reduced testing of 1 assembly
randomly selected from each group of 50 or less assemblies submitted for Government inspection may be instituted
following compliance with all quality conformance test requirements of 2 sample assemblies selected from 2
consecutively submitted groups of 10 assemblies. Normal testing of 1 in 10 ring assemblies shall be reinstated
upon the failure of an assembly to comply with any of the quality conformance test requirements.
4.5.2 Failure. Upon failure of a quality conformance sample Government inspection of other tests may continue:
however, acceptance will be withheld pending correction of the defects responsible for the rejection. The procuring
activity shall be notified of accepted lots possibly containing similar defects. When the cause of rejection has been
determined and corrective action within the limitation of the design disclosure taken by the contractor to the
satisfaction of the Government Inspector, then production maybe continued and acceptance inspection resumed.
In the event the cause of rejection cannot be determined, the procuring activity shall be so advised.
