4.3.1 First article inspection failure. Deficiencies found during, or as a result of, first
article inspection shall be cause for rejection of the first article sample until evidence has been
provided by the contractor that corrective action has been taken to eliminate the deficiency. Any
deficiency found during, or as a result of, first article inspection shall be evidence that all items
already produced prior to completion of the first article inspection are similarly deficient unless
contrary evidence satisfactory to the contracting officer is furnished by the contractor. Such
deficiencies on all items shall be corrected by the contractor. The Government will not accept
products until first article inspection is completed to the satisfaction of the Government.

4.4.1.1 Sampling. Samples from an inspection lot for conformance inspection shall be
selected in accordance with ANSI/ASQC Z1.4. Each sample selected shall be inspected as
specified herein for the defects listed in table III. Conformance to a lot shall be accepted when
zero (0) defects are found and rejected when one (1) or more defects are found.

4.5.1 Materials and construction. Conformance to 3.2 thru 3.3.1 shall be determined by
inspection of contractor records providing proof or certification that design, construction,
processing, and materials conform to requirements. Applicable records shall include drawings,
specifications, design data, receiving inspection records, processing and quality control standards,
vendor catalogs and certifications, industry standards, test reports, and rating data.
4.5.2 Performance tests.
4.5.2.1 Selectivity. This test shall be conducted in conjunction with the test specified in
4.5.3. If a continuous-recording instrument is used, the entire transmission curve shall be
examined for conformance to the curve shown in figure 1 and to the requirements of 3.4.1.1.1. If
readings have been taken at 10 millimicrons intervals only, the values shall be compared with the
values shown on figure 1 for each corresponding wavelength. A value of 50% or less for the
620 millimicrons reading and a value of 50% or more for the 640 millimicrons reading shall
constitute conformance to requirement of 3.4.1.1.1a.
