When we use a sampling plan at our organization, we use the AQL 1.0 OR 10.0 depending upon the characteristic to determine what our sample size will be when having a lot size of XXX.
Steve, I am not at work at the moment and will need to let you know what we state for 2000 pcs. I good baseline is 10%. I do not feel anything is incorrect with that amount of sampling. But, I just wouldn't feel comfortable shortening it without my data stating that I have had no rejects whether by RMA or Inspection.
