MIL-T-46313B(MD)
considered to be within 10%. of the product tolerance for which it is
intended, this inherent error in the test equipment design must be con-
sidered as part of the prescribed product tolerance limit. Thus, concept,
construction, materials, dimensions 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,
4.5.3 Test equipment.- In conjunction with 4.5.2.2, the following
standard test equipment shall be utilized in the performance of the
applicable tests as specified in 4.6 and 4.7.
