04 / Acceptance and handover
Prove the result under a representative production condition
Run qualified batches at hold boundaries, measure time-dependent properties using representative samples, and verify timer logic, environmental control, endpoint, transfer readiness and overdue disposition. Sample spatially and by time to verify lump removal, hydration, viscosity, particle distribution, temperature, air pickup, cycle time, heel and repeatability. 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.
