Ron, I'm not clear on what you're asking.
Normally with a new supplier, we would first do a 1 pc. sample to ensure gage correlation with the supplier, and then a first article order (quantity depends on the type of part) that we do a full inspection and test on. (typically non-destruct and destruct testing)
Once the parts have passed the first article, we add the supplier to our Approved Supplier List and then begin production purchases.
The supplier's reject rate is then figured on a monthly basis, as part of our supplier metrics.
It sounds like you're not doing a first article, but trying to track them in production?
