04 / Acceptance and handover
Prove the result under a representative production condition
Run representative products at sustained flow boundaries, trend pressure and temperature, and verify distribution, stability, no damaging recirculation, capacity, yield and control response. Measure inlet condition, pressure, temperature, flow and resulting distribution; challenge load and wear states; verify stability, hygiene, capacity and repeatable recovery after cleaning. 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.
