MIL-T-46590C
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 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), all inspections shall be performed under
the following conditions:
a.
Temperature: room ambient (68 to 77F)
b.
Altitude: sea level
c.
Humidity: 50 percent relative, maximum
d.
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, one set of unassembled parts without plating or final
protective finish, and fifty shear pins from the same lot of shear pins tested by the contractor. The sample shall
be manufactured in the same manner, using the same materials, equipment, processes, and procedures as used
in regular production. All parts and materials, including packaging and packing, must be the same as will be
used for regular production and shall be obtained from the same source of supply. After inspection and
provisional acceptance at source, the first article sample shall be inspected for all requirements of the drawings
and specifications. The Government reserves the right to require new first article samples until an acceptable
sample is submitted (see 6.3).
