4. QUALITY ASSURANCE PROVISIONS
4.1 Responsibility for inspection. Unless otherwise specified in the contract or purchase order, the
contractor is responsible for the performance of all inspection requirements (examinations and tests) as
specified herein. Except as otherwise specified in the contract or purchase order, 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
inspections set forth in this specification where such inspections are deemed necessary to ensure supplies and
services conform to prescribed requirements (see 6.2).
4.1.1 Responsibility for compliance. All items shall 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 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 acceptance of defective material.
4.1.2 Quality assurance terms and definitions. Reference shall be made to MIL-STD-109 to define
the quality assurance terms used.
4.1.3 Inspections. Inspections shall be in accordance with MIL-A-2550.
4.2 Classification of inspections. The inspection requirements specified herein are classified as
First article inspection (see 4.4)
Quality conformance inspection (see 4.5)
4.3 Inspection conditions. Unless otherwise specified (see 6.2), all inspections shall be performed
under the following conditions:
Temperature: room ambient (68 to 77°F)
Altitude: sea level
Humidity: 50 percent relative, maximum
Atmospheric pressure: 14.7 psi
4.4 First article inspection. At the beginning of regular production, the contractor shall submit an
initial production sample to a Government approved facility for evaluation. The sample shall consist of five
metal parts assemblies, nine sets of unassembled parts, and one set of unassembled parts without plating or
final protective finish. The sample shall be manufactured in the same manner, using the same materials,
