I'm currently dealing with really large # of samples and want to set my AQL. So far, I've only seen these two as common standards for major and minor nonconformities, respectively. May I ask if there is a trustworthy reference for this? Most that I've seen are websites only. Thank you very much!
To determine the AQL level of a product use the table that is recommended by ISO 2859, NF06-022, DIN 40080, BS 6001, ANSI/ASQC Z1.4.
The three common levels are 0, 2.5 and 4%. Military and medical often use 0 to 1.5. There is no fixed level. It is determined by the product and the consequences.
I don't know the sample you're dealing with.
In any case, I think the ISO 28590: 2017 standard can be useful for your job.
ISO 28590:2017 provides a general introduction to acceptance sampling by attributes and provides a brief summary of the attribute sampling schemes and plans used in ISO 2859‑1, ISO 2859‑2, ISO 2859‑3, ISO 2859‑4 and ISO 2859‑5, which describe specific types of attribute sampling systems. It also provides guidance on the selection of the appropriate inspection system for use in a particular situation.
I hope I was helpful
Joseph L Alvarez Thank you very much for the prompt reply! I am using ANSI and the ISO 28590 is very useful. Although I am still confused as to why the three common levels are 0, 2.5 and 4% and their basis.
Sergio Sbrenni I am currently reading your reference. Thanks!
