4.4.1 Failure of sample. Should any one item of a special
sampling fail to meet the specified test requirements, acceptance
of the product shall be suspended by the Government until necessary
corrections have been made by the contractor and a resubmitted
sample has 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 of MIL-I-45607.
4.5.2 Contractor-furnished inspection equipment.
4.5.2.1 Contractor design. The contractor shall design and
supply inspection equipment compatible with the "Methods of
inspection" 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 percent 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 ensure that the
test equipment will reliably indicate acceptability of a product
which does not exceed 90 percent of the prescribed tolerance limit
