4.3 First article requirements.
4.3.1 First article inspection. When first article or qualification inspection is
required in the part or equipment specification, the finishes shall be inspected for
compliance with Tables VIII and IX and with equipment performance requirements.
4.3.2 Inspections to be performed. The sample will be subjected to the tests
specified in 4.5. The Government may also require testing to assure conformance to any
or all of the applicable requirements of this specification.
4.3.3 Rejection of first article samples. If any sample fails to comply with any of
the applicable requirements, the first article quantity shall be rejected. The Government
reserves the right to terminate its inspection upon failure of any sample to comply with
any of the stated requirements. In the case of qualification inspection, the specification
requirements shall apply.
4.4 Conformance inspection. Conformance inspection of parts and equipment for
finishes shall be in accordance with Tables VIII and IX.
4.5 Methods of inspection.
4.5.1 Color. The color conformance of the specified paint film shall be verified
by comparison with an appropriate FED-STD-595 color chip. CARC paints may require
batch verification depending on the paint specification requirements (see para 6.3.5.1).
4.5.2 Adhesion of paint. At the discretion of the Government, a representative,
though inconspicuous, portion of the painted surface of the sample unit, or a piece of
scrap finished at the same time and in the same manner, shall be scraped with a sharp
knife. The paint shall peel evenly from the surface rather than chip or flake. In addition,
it shall be difficult to nick through the paint film to the substrate with a thumbnail.
Failure to pass this test shall be considered a major defect in accordance with Table VIII.
Acceptable units subjected to this test may be delivered on contract after all visible
damage to the painted surface is repaired to the satisfaction of the Government.
Tape Tests
Unless otherwise specified a minimum of two sample units or test specimens
representative of each day s production shall be run through all steps of the regular
production process including painting. Adhesion by tape testing of the painted specimens
should be determined within 24 hours drying for single coat applications. A two coat
paint should be tested within a maximum of 72 hours drying time. If any test unit or
specimen fails any of the tape tests, all items processed since the last acceptance shall be
rejected and corrective action taken.
