Thus, concept, construction, materials, dimensions and tolerances used in the design of test equipment shall be so s
38、elected 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 nonconforming.
