04 / Acceptance and handover
Prove the result under a representative production condition
Run empty, flooded, turndown and restart cases with representative powder, trend drive load and mass rate, and verify seals, clean-out, heel and shutdown isolation. 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.
