04 / Acceptance and handover
Prove the result under a representative production condition
Conduct worst-case line clearance with seeded discrepancies, inspect every defined boundary, and verify detection, reconciliation, sign-off, status display and controlled release to production. Use representative powders to verify containment, transfer rate, heel, feeder accuracy, foreign-material control, clean-down, changeover and reconciled mass delivery. 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.
