a. The appropriate inspection level is selected as follows:

Inspection Level II - Disputes (Codex referee purposes sample size), enforcement or need for better lot estimate.
b. Determine the lot size (N), i.e. number of primary containers or sample units.
c. Determine the number of sample units (sample size (n)) to be drawn from the inspection lot, consideration being giving to container size, lot size, and inspection level.
d. Draw at random the required number of sample units from the lot giving proper consideration to code or other identifying marks in selection of the sample.

f. Refer to the appropriate Sampling Plan in Appendix I.
g. Consider the lot acceptable if the number of defectives is equal to or is less than the acceptance number (c) of the appropriate Sampling Plan contained in Appendix I of this document.
h. Consider the lot as failing if the number of defectives exceeds the acceptance number (c) of the appropriate Sampling Plan contained in Appendix I of this document.
