04 / Acceptance and handover
Prove the result under a representative production condition
Qualify analysts and equipment, compare repeated sections and link findings to head, tooling, lot and package integrity. Retain measured evidence for seam specification and component family and frequency, limits and disposition 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.
