08 Apr Aql Agreement
Make sure you get the supplier`s approval for your plan. That may be the hardest thing! Can you provide more information on the cumbersome statistics that underlie the disagreement between the number of defective items accepted and the actual percentages? My question is how the values in the review tables are ultimately calculated. Thank you in advance for your help! AQL tables are a series of diagrams that allow users to easily determine the number of samples required for quality testing as well as the number of defective units allowed based on a given AQL. These tables are part of ISO 2859 and are equivalent in all national and international standards bodies, including ANSI. Once an AQL has been identified, the diagrams allow buyers to agree on quality control standards. Before production, we recommend that you enter into an agreement with your plant in order to obtain a mutual understanding of the results that you consider acceptable results. Hi Renaud Belle article and responds. I have a question about zero acceptance sampling plans. In fact, you don`t use AQL, but the term “Associated AQL.” In the sampling plans mentioned above, I understand that a 1% AQL suggests that there is a 95% chance that a batch containing 1% or less of defects will be accepted (or 5% chance of the same lot being rejected – manufacturer`s risk). With the OC curve, you can determine the probability that other batches with higher or lower error levels will be rejected. How do I make similar arrangements on the C-O plans? I have the book by Nicholas Squeglia, but I still have an explanation to make. My suppliers insist that I use the ANSI/ASQ plan, but I prefer the C-0. Thanks, unless you want to use a hypergeometric distribution in Excel, I highly recommend you see the video I posted in the article above.
It explains how you get to the desired values without the calculations being done. It is ok. I answered that in the third question-and-answer session on this page.
