MIL-STD-1916 DOD Preferred Methods for Acceptance of ProductThe purpose of this standard is to encourage defense contractors and other commercial organizations supplying goods and services to the U.S. Government to submit efficient and effective process control prevention procedures in place of prescribed sampling requirements.

multiple of pallet size.  Availability and capability of screening and sampling crews are yet further considerations.

The plan cited in Table IV consists of the largest i  number and the smallest f  number combination.  Plans whose i  is larger than the tabulated i, or whose f  is smaller than the tabulated f, are not permitted.  Producers willing to sample at rates larger than f  can reduce i substantially.

The procedure that allows choice is presented by way of the preceding continuous sampling example situation as initially described, subject to one modification:  the producer prefers to start with a plan having an i  of 50 instead of the 116 specified.  The procedure to determine a valid f  is as shown in figure 5.

FIGURE 5.  Procedure to determine a valid f.

Therefore, an i of 50 may be used in lieu of 116 if f is increased from 1/48 to 1/6.

If it is f that is preselected, the corresponding i may be found by trial and error, that is, by iterative implementation of the procedure described.

The printed numerical results have been rounded to 4-decimal accuracy.  However, use of the procedure requires that all calculations be performed with at least 6-digit precision. Evidence supporting the validity of numerical results shall be maintained and be available for review upon request.  Proper execution of the procedure ensures Tables IV and II are

comparable with respect to the average fraction inspected and the average outgoing quality limit.
