If you can assume that the data collected is representative of all months, then you should be O. However, Inspection Level I may be speci? As you may already know, there are many ways to detect contamination.
When inspecting components on tape and reel, pulling parts at random can present a problem in a pick and place operation. Once that confidence is restored, then you go back to what you inspected originally.
ANSI/ASQ Z1.4–2003 (R2013): Sampling Procedures and Tables for Inspection by Attributes
Zero defect sampling is an alternative method to the obsolete Mil Std E sampling scheme previously used to accept or reject products, and the axqc ANSI Z1. The number of sample units inspected shall be equal to the sample size given by the plan.
The product is a liquid dietary supplement. An American national Standard implies a consensus of those substantially concerned with its scope and provisions. D Acceptance Quality Limits normal inspection 1. This standard is not included in any packages.

If the lot or batch is of an isolated nature, it is desirable to limit the selection of sampling asac to those, associated with a designated AQL value, that provide not less than a speci?
Inspection of incoming lots whose quality levels vary around a? A schematic diagram describing the sequence of application of the switching rules is shown in Figure 1. What we did was z1.4-2008 inspect at the beginning and the end of each tape. The right is reserved to inspect every unit submitted by the supplier for speci?

The simple rule is that the smaller the difference, then the larger the sample size. Then, you would pick the AQL you need based on the risk you are willing to take for the process average of percent defective.
Normal inspection will be used at the start of inspection unless otherwise directed by the responsible authority. This paper discusses the development of zero defect sampling and compares it to Mil Std E. Ideally, a quick non-destructive test would permit you to inspect every unit and to divert faulty units to a cleaning process.
When agreed upon by responsible authority for both parties to the inspection, that is, the supplier and the end item customer, the requirements of 8. The operating characteristic curves of scheme performance are based on the use of limit numbers in switching to reduced inspection and are approximately correct when the limit numbers for reduced inspection are not used under Option 8.
We would like to justify that we can abide by level I or even lower if possible.
