4.5.2 Contractor furnished inspection equipment,
4,5.2.1 Government design .- Unless otherwise specified in the con-
tract, all inspection equipment specified by drawing number in specifica-
tion or SQAP forming a part of the contract shall be supplied by the con-
tractor in accordance with technical data listed in the technical data
package (TDP).
4.5.2.2 Contractor design.- The contractor shall design and supply
inspection equipment compatible-with the "Test Methods and Procedures"
specified in 4.6 of this specification and with the component inspection
procedures specified in "Examination" and "Test Facilities" requirements
of MIL-F-13926. Since tolerance of test equipment is normally considered
to be within 10% of the product tolerance for which it is intended, this
inherent error in the test equipment design must be considered as part of
the prescribed product tolerance limit. Thus, concept, construction, ma-
terials, dimensions and tolerances used in the design of test equipment
will reliably indicate acceptability of a product which does not exceed
90% of the prescribed tolerance limit, and permit positive rejection when
non-conforming, Construction shall be such as to facilitate routine cali-
bration of test equipment.
4.5.2.3 Inspection equipment design requirements.
4,.5.2.3.1 Telescope clamping mechanism.- The Adapter, Final Inspec-
tion, Azimuth F11750709 together with a suitable stand shall be utilized
in performing the telescope clamping mechanism test. The stand shall have
the necessary stability for positioning the adapter so that it maintains
the mounting dovetail surface and dovetail axis of the mount in a vertical
plane within plus or minus one degree.
4.5.2.3.2 Torque requirements.- The torque wrench type tester for
testing the telescope clamping mechanism shall have a range of zero to
fifty inch-pounds. The accuracy of the torque wrench type tester shall
be five percent throughout its entire zone of excursion. The torque
wrench shall be equipped With suitable adapters to accommodate testing of
the appropriate assembly.
4.5.2,3.3 Wall target.- The wall target shall contain a vertical
and horizontal crossline. It shall be positioned 6 to 12 feet in front
of the sightunit under test.
4.6 Test methods and procedures.
4.6.1 Telescope clamping mechanism.- Conduct this test with the mount
positioned on the testing equipment specified in 4.5.2.3.1. Position the
target so that the intersecting point of the vertical and horizontal target
lines are coincident to the geometric axis of the clamp for the telescope.
Install the telescope in the clamping mechanism of the mount and lock the
clamp by applying a force of 5 to 7 inch-pounds to the locking lever.. By
means of the elevation and azimuth knobs adjust the line of sight of the
telescope so that its vertical and horizontal reticle lines are superim-
posed on the image at the vertical and horizontal target lines. The
