OPS.18:5.3 - The lot decision uses its own plan

A separate constructed supplier lot arrives after the process signal above. The supplied product-acceptance plan defines the lot, defects, sampling and disposition authority. For this illustration, it specifies a random sample of fifty items and acceptance only if at most one is nonconforming. Its qualification for the actual product and producer/consumer risks belongs to the supplied plan.

The sample contains two nonconforming items. The acceptance practitioner rejects or segregates the lot as the plan requires and obtains the prescribed rework or supplier response. Even if a process chart for that producer has no current signal, the lot fails this stated acceptance rule.

If the lot had passed, the result would support its disposition under the plan’s risks. It would not settle the earlier process investigation. If the plan or its risk qualification is missing for the actual use, obtain that result before relying on this sample rule; these illustrative numbers do not provide a general acceptance plan.
