Less discrimination means that the actual Acceptable Quality Level AQL on the table underestimates the true AQL, as the sample size has been reduced from the table-suggested sample size i.
The product is a liquid dietary supplement. Can I get further explanation of how one would justify that less discrimination is needed?
ANSI/ASQ Z – Sampling Procedures and Tables for Inspection by Attributes
However, we run a variety of tests, including microbial and heavy metal testing. If you use one of the special sampling plans based on the cost of the test, it is helpful to calculate the actual AQL and Limiting Quality LQ using the following formulas.
Steven Walfish Secretary, U. Justification of a sampling plan is based on risk and a sampling plan can be justified based on the cost of the test, assuming you are willing to take larger sampling risks.
