04 / Acceptance and handover
Prove the result under a representative production condition
Verify installation and product contact, inspect retained findings by defined method, challenge access and cleaning, and trend magnet condition, contamination source and corrective actions. 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.
