04 / Acceptance and handover
Prove the result under a representative production condition
Challenge approved defects and normal variation and verify detection, false reject, secure removal and correlation. Retain measured evidence for target seam and closure defects and challenge, reject and correlation plan with method, sample position, limit, deviation, witness, approval and review trigger. Use representative can and end lots, position-stratified seam teardown and integrity tests, controlled fill and pressure measurements, defect challenges, coating and corrosion review, thermal and distribution conditioning, and material-to-pallet traceability. Put the sample or test material, method, instrument, production state, duration, limit, witnesses, retained record and deviation authority in the protocol before testing begins. Requalify when a product, package, site, speed or connected system invalidates the accepted basis.
