MIL-DTL-62422D(AT)
test for the appropriate inspection lot size shall constitute a failure of the entire lot. The rejected
item(s) may be repaired or corrected and resubmitted for inspection. If the contractor utilizes
sampling inspection as an element of his inspection system, rejected inspected lots may be
resubmitted for acceptance if the contractor performs 100 percent inspection on the lot for those
characteristics which were defective and resulted in rejection of the lot and removes all defective
units or obtains procuring activity approval to resample the lot due to the insignificance of the
defects. Resubmitted lots shall be kept separate from new lots and shall be clearly identified as
resubmitted lots.
4.4 Examinations.
4.4.1 Visual and dimensional examination. Filters shall be visually and dimensionally
examined for completeness of manufacture, freedom from defects other than optical quality
defects, proper item identification, conformance to applicable drawings and specifications, and
workmanship.
4.4.2 Materials and construction. Conformance to 3.2, 3.2.1, and 3.3 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.
4.4.3 Defects. Conformance to 3.2, 3.3, 3.5.1, 3.5.2, 3.5.3, 3.5.4, and 3.5.6.3 shall be
determined by examination for the defects listed in table II. Examination shall be visual, tactile,
or by measurement with standard inspection equipment.
4.5 Test methods and procedures. The calibration of measurement and testing
equipment shall be in accordance with ANSI/ISO/IEC 17025 and ANSI/NCSL Z540.3. Detector
responsivity calibrations (see 4.5.1.2) shall be used in all measurements.
4.5.1 Test equipment requirements. The following test equipment shall be used.
4.5.1.1 Monochromater. The monochromater shall have a nominal half-bandwidth of
2 nm or less.
4.5.1.2 Detectors. The spectral responsivity of the detectors shall be known. The
detector responsivity versus incident light intensity shall be known for the light ranges
appropriate for each measurement.
4.5.2 Environmental weathering (first article only). To determine conformance to 3.4,
upon completion of the examinations in 4.4 and the tests in 4.5.3 through 4.5.11, the filters shall
be subjected to the environmental conditions as specified in MIL-STD-810, method 505,
