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. All inspection equipment
specified by drawing number in specification or QAP forming a part
of the contract shall be supplied by the contractor in accordance
with technical data included in the Technical Data Package List
(TDPL).
4.5.2.2 Contractor desiqn. In the absence of Government
inspection equipment 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,
materials, demensions, and tolerance 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.
4.5.2.3.1 Temperature testing. The volume of the test
chamber shall conform to the test facilities requirements of
MIL-F-13926. The air temperature at the control sensor shall be
in accordance with the specified requirements within plus or minus
2.5 (1.4C). The temperature gradient across the
cross-sectional area occupied by the test item shall not exceed
0.5 per foot in any direction. The heat source of the test
chamber shall be so located that radient heat, if used, will not
fall directly on the test item. Thermocouples or equivalent
temperature sensors utilized to determine or control the specified
chamber temperature shall be centrally located within the test
chamber within the supply airstream, or in the return airstream,
whichever provides the specified test condition at the item under
test and shall be baffled or otherwise protected against radiation
effects.
