04 / Acceptance and handover
Prove the result under a representative production condition
Induce or reproduce credible poor-flow states safely, verify detection before dose loss, and demonstrate authorised flow-aid, isolation, recovery, inspection and deviation records. 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.
