The OC curve shows the probability, Pa, that a submitted lot will be accepted for any given fraction defective p. This paper discusses the development of zero defect sampling and compares it to Mil Std E. The sample size to be used is given by the new code letter, not by the original letter. Samples may be drawn after all the units comprising the lot or batch have been produced, or anxi may be drawn during production of the lot or batch. Finding the right balance around these considerations is highly dependent on the nature of the issue, cost of failure, and local resources. The product is a liquid dietary supplement. Let me expand with a more technical explanation. Inspection Procedure The general procedure Figure 3 in designing the sampling plan is the following. The acceptance of a lot is not intended to provide information about lot quality. The responsible authority shall determine whether normal or tightened inspection shall be used on reinspection and whether reinspection shall include all types or classes z1.4-2080 nonconformities or only the particular types or classes of nonconformities which caused initial rejection.įor an AQL of 0.

Instead, these defects are added based on the product attribute tablet count, closure, etc. Z1.4:2008 inspection levelsĪlso once removed, the samples would have to be put back on tape for use.
