I'm needing some help interpreting some of the tables in the MIL-STD-105 (E) standard. In particular the Single Sampling Plans tables (Table II).

My confusion is this: how/why is it that the AQLs are specified up to 1000?

Aren't AQLs expressed as percentages? In practice, is there any reason to even consider the columns of AQL >= 100?

Also...

I know that MIL-STD-105E has been superceded by ANSI/ASQC Z1.4, but as I understand, they are still quite similar. So for anyone (like me) just wanting to explore acceptance sampling without having to buy the ANSI/ASQC standard, the MIL-STD-105E can still be a good starting point.

Can anyone familiar with the differences between the two please confirm?

Thanks in advance!
