Some interpret it to mean if a lot has AQL percent defective or less, a lot would have a high probability of being z11.4-2003 based on the sampling plan. 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. Anwi to Checkout Continue Shopping.

For example, at an AQL of 0. This is not an uncommon question. If you want to use the standard, the sample size should be based on the number of samples, not the number of rolls. That is the pure definition of the alpha risk.


A stable process or production is less about a capability index, and more about the control chart of the data showing a stable process.

If you choose a plan that is tightened or reduced to start with, you z1.4-20003 will either spend too much on inspection tightened or risk having bad product go to the customer reduced.

The switching rules are there to protect the producer when the anai is running very well or it has problems. If your customer is not requiring a particular plan, you can use what you want. In medical device manufacturing the key point is to have the plan accept on zero defectives. Steven Walfish Learn more about visual inspection here. It is based on past lawsuits. It is important to understand what you are doing when using sampling plans, what they are and the protection you are trying to ensure.

My question is about z1.4-2003 aluminium foils, films used in packaging and sticker labels received in rolls which are wound around a core.

A normal plan is generally used and the switching rules come in when the clearance number has been obtained. You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server. It provides tightened, normal, and reduced plans to be applied for attributes inspection for percent nonconforming or nonconformities per units. In other words, the process is stable over time.


It is a business decision for you to make if your customer is not demanding it. I have not used the reduced sampling before, so am curious what should be done in this instance.

Some processes may never switch.

Total noncomforming less than limit number? Do I trust the acceptance sampling inspection or react? Initially you start at normal amsi, and can move to either z1.4-2030 or reduced inspection depending on how lots are dispositioned.

You may delete a document from your Alert Profile at any time. It is expected that the product quality level will be less than the AQL to avoid excessive non-accepted lots. Answer FDA does not and can not tell you what sampling plan is to be used. It is a business decision, no reason for any exceptions. These plans were developed to be z1.4-203 as documented. Would I use 1.

This means that by your definition, Camp 1 is correct. Does production stability mean capability? The sample size to be used is given by the new code letter, not by the original letter.

Then you select the sample size to provide the level of protection you are striving to ensure.
