4.5 Inspection equipment.-  Except as otherwise provided for by the
contract, the contractor shall supply and maintain inspection equipment
in accordance with the applicable-requirements of MIL-I-45607.
4.5.1 Government furnished inspection equipment.- Where the contract
provides for Government-furnished test equipment, supply and maintenance
of test equipment shall be in accordance with the applicable requirements
specified in MIL-I-45607.
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
contractor in accordance with technical data listed in the Technical
Data Package (TDP),
4.5.2.2 Contractor design.- The contractor shall provide inspection
equipment compatible with the "Test Methods and Procedures" specified in
4.6 and with the "Component Inspection" 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,
materials, dimensions and tolerances used in the design of test equipment
shall be so selected and controlled as to insure that the 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
calibration of test equipment.
4.5.2.3 Inspection equipment design requirements.- The test equipment
provided in accordance with 4.5.2.2 shall meet the following requirements:
(a) Target.-  Figure 1 is used in conjunction with Fixture
8204694 and a viewing collimating telescope to facilitate checking the
requirements of paragraphs 3.5.2 and 3.5.5; and when in use, the target
is placed 12 foot, 6 inches from the collimator objective lens when the
collimator is placed in the fixture. The target is used to determine
either the horizontal and/or vertical positioning of the reticle line to
their respective means for mounting and also for checking parallelism of
the open sight with respect to the reticle. The target contains mil
blocks (E) at each end of the Vertical Line "C". The size of a mil block
for these targets (for all practical purposes) can be determined by
