Inspection requirements for 3.5 x 10x day optic scope, hard case, soft case and magazine pouches during the overhaul process.

The contractor shall visually inspect the 3.5 x 10x day optic scope, hard case, soft case and magazine pouches. Parts that fail to meet the visual inspection shall be replaced. Defective components, to include damage to the protective finish that cannot be reclaimed shall be replaced. Surface imperfections that affect appearance but do not affect form, fit and function shall be acceptable.

Visually inspect the hard case for air tight integrity, broken latches, hinges, gasket, breaks, burrs, corrosion, cracks, dents gouges, nicks, mutilation, missing coatings, and unauthorized alterations.

Visually inspect the soft case and magazine pouches for tears, broken zippers and straps and unauthorized alterations.

Visually inspect the 3.5 x 10x day optic scope per MIL-PRF-13830B. Defects which will not impair the performance of the day optic scope shall be permissible. Surface imperfections that affect appearance but do not affect form, fit and function are acceptable. Whether a particular defect shall be permitted will depend on the location of the element in the finished optical system. Defects in the elements not near the focal plane are not as important as in elements which lie in or near a focal plane.

The order of importance is as follows:

a) Most critical surfaces, (etched surface of reticle, surface of collective lenses in a focal plane).

b) Less critical surfaces, (surface of ocular field lens nearest the reticle, collective lens, center lens or prism surfaces near a focal plane).

c) Least critical surfaces, (all other surfaces of objectives, prisms, erector, and eye lenses).

For the classification of characteristics, the following definitions apply:

Critical - A critical defect is a defect that would result in hazardous or unsafe conditions for individuals using, maintaining, or depending upon or a defect that is likely to prevent performance of the tactical function of a weapon system.

Major - A major defect is a defect, other than critical, that is likely to result in failure, or to reduce materially the usability of the unit for its intended purpose.

Minor - A minor defect is a defect that is not likely to reduce materially the usability of the unit for its intended purpose, or is a departure from established standards having little bearing on the effective use or operation of the unit.

Cleanliness: Each scope shall be examined through the objective and eyepiece ends with the unaided eye. Inspection for moisture shall be made by the technique of shadowing. Inspection for dust particles shall be made by viewing a uniformly illuminated field having a brightness of approximately 300 apparent foot-lamberts.

Target. Targets used in testing may be either actual size targets or miniature targets contained in collimators. The actual size targets can be made by printing black lines on a white background. The target in a collimator may be an etched or photographic reticle duplicating in miniature form, a full size target. The targets will vary, as required, by the detailed specification, from plain crosslines to targets containing a plumb line, level line, tolerance limit lines, and graduated scales
