    On the ANSI/MIL STD acceptance sampling tables there are AQLs listed at 100 and above.  What are these used for?  If the sample size is 3 how can you possibly find 45 defectives?  What am I missing?

    Mark,You are simply missing the difference between “defectives” — a part that doesn’t meet spec — and “defects” — any problem with the part.Suppose you have a printed circuit borad with 1000 solder connections. If you have 1 bad connection or 45 bad connections the part is bad. The count for defectives is 1, but the count for defects is 45.When you think “defective”, think “part”.
    When you think “defect”, think “opportunity”. Tim F

    To expand on what Tim F said, remember that AQLs of over 10 are only expressed as defects (or nonconformities) per hundred units, not in percentages defective (or nonconforming).
