Here's my situation. Customer requirements call for sampling under AS9138 Table A1, which I understand to describe 1 minus the IRR, per my reading of § 4.4.2(e).
No AQL is mentioned in the customer requirements.
AS9138 refers me to the tables in SCMH § 3.7.4 for sample sizes. Those tables are based on AQL, rather than IRR. So I'm off to look for a conversion table.
I find the IAQG's AS9138 FAQ. FAQ #20 provides an AQL to IRR conversion table, but warns "This conversion process does not work backwards. If a specification has given an IRR, it is important not to use an AQL method to replace it."
I am thus at a loss to get from AS9138 Table A1 to the appropriate sample size table in in SCMH § 3.7.4.
Any assistance would be appreciated.
