the contractor and the resubmitted samples have been approved (see 4.3.3).
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.
126.96.36.199 Government design.- Unless otherwise specified in the con-
tract, all inspection equipment specified by drawing number in specifi-
cations or SQAP forming a part of the contract shall be supplied by the
contractor in accordance with technical data listed in the List of
Inspection Documents when provided with the Technical Data Package (TDP).
188.8.131.52 Contractor design.- The contractor shall provide inspection.
equipment compatible with the "Test Methods and Procedures" speciifed in
4.6 of this specification and with the "component Inspection" and "Test
Facilities" requirements of MIL-F-13926. Since tolerance of test equip-
ment 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 907' of the prescribed tolerance limit,
and permit positive rejection when non-conforming. Construction shall
be such as to facilitate routine calibration of test equipment.
4.6 Test methods and procedures.
4.6.1 Storage temperature.- The storage temperature test for the plotting
boards at minus 80 degrees and plus 160 degrees Fahrenheit shall be
conducted in conformance with 3.4.1 and the "Test Facilities" of MIL-F-
13926. Upon return to standard ambient temperature the plotting boards
shall be subjected to a visual and tactile examination and shall show no
evidence of physical failure such as cracks, splits, or warpage. The
plotting boards shall then be subjected to all the tests specified herein.
4.6.2 Operating temperature.- The temperatures cycling for the
operability tests of the plotting boards at the specified temperature
extremes shall be conducted in accordance with 3.4.2 and the "Test Facilities"
of MIL-F-13926. When the plotting boards are thermally stabilized at minus
40 degrees and plus 150 degrees Fahrenheit, respectively, they shall be
subjected to the operability tests specified in 4.6.6.
