For more information about AQL, please view the resources here. This point is not FDA but legalese. Does production stability mean capability?

The AQL is a parameter of the sampling scheme and should not be confused with a process average which describes the operating level of a manufacturing process. Answers From Charlie Cianfrani: This means for the lot size with code letter D and with an AQL of 0.

A anzi plan is generally used and the switching rules come in when the clearance number has been obtained. I have two questions.

Difference between ANSI/ASQC and ANSI/ASQ

Standards Subsctiption may be the perfect solution. Steven Walfish Learn more about visual inspection here. The sample size to be used is given by the new code letter, not by the original letter.

Starting at code letter D, move across that row until you intersect at the AQL 0. Just looking for z14 on the AQL numbers, what they mean, and how to interpret them. But depending on znsi AQL, a sample size of 8 would be inappropriate, so the standard has arrows to delineate alternative sample sizes to reach the target AQL.

It provides tightened, normal, and reduced plans to be applied for attributes inspection for percent nonconforming or nonconformities per units.

I can decide to chose the number of rolls to sample from using the tables given in Z1. It is a business decision for you to make if your customer is not demanding it. Proceed to Checkout Continue Shopping.

A stable process or production is less about a capability index, and more about the control chart of the data showing a stable process. I am confused about the values used for AQLs.

Your Alert Profile lists the documents 203 will be monitored. Then you select the sample size to provide the level of protection you are striving to ensure.

ANSI/ASQ Z1.4-2003 and ANSI/ASQ Z1.9-2003

If you want to use the standard, the sample size should be based on the number of samples, not the number of rolls. In the and versions it explains this in section 9. This means that by your definition, Camp 1 is correct. The standard does not specify the probability of acceptance explicitly.


This standard is also available to be included in Standards Subscriptions. That is the pure definition of the alpha risk. It is more important to understand the theory behind the tables than to mechanically use the tables.

Ask the Standards Experts. Code letter is D as in the question below. FDA does not and can not tell you what sampling plan is to be used.

Question My question is about sampling aluminium foils, films used in packaging and sticker labels received in rolls which are wound around a core.

Which is correct or more appropriate to reflect supplier quality?

Z14. your customer is not requiring a particular plan, you can use what you want. Do you have information around this debate over which sampling plans are acceptable by the FDA? I hope this helps.
