04 / Acceptance and handover
Prove the result under a representative production condition
Record cycle states across rate limits, challenge high level and failed discharge, and reconcile receiver fills, filter pressure, transfer time, delivered mass and residual powder. 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.
