MIL-DTL-6193D
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 ensuring that all products or supplies submitted to the Government for
acceptance comply with all requirements of the contract. Sampling inspection, as part of manufacturing
operations, is an acceptable practice to ascertain conformance to requirements, however, this does not
authorize submission of known defective material, either indicated or actual, nor does it commit the
Government to accept defective material.
4.3 Qualification inspection. Qualification inspection shall consist of the examinations and tests
specified in table IV. Samples subjected to group I testing shall be divided and subjected to group II and
group II tests. Qualification Inspections and tests shall be performed at a laboratory acceptable to the
Government (see 6.3) on sample units produced with equipment and procedures normally used in
production. Use of alternate materials, plating, and processes shall be identified in the product test
documentation (see 3.3).
4.3.1 Qualification test articles. Samples for qualification shall be representative of the products
proposed to be furnished to the Government. Qualification test articles shall consist of 10 universal joints
for each type and size of universal joint for which qualification is desired.
