DonkeyKong,
It was way to long ago when I was a young QE, but we will try to get the old gray cells working again....
Rejectable Quality Level (RQL) is used interchangeably with Limiting Quality Level (LQL) or Lot Tolerance Percent Defective (LTPD). The tables you want are Dodge-Romig Sampling Inspection Tables. You need an estimate of the incoming quality level (process average) and you need an RQL or LQL level and lot size. The tables are set to be used with rejected lots being 100% inspected which then gives you the Average Outgoing Quality Level (AOQL) you are looking for.
Hope this helps,
Rick
