04 / Acceptance and handover
Prove the result under a representative production condition
Use authority-approved methods with representative worst particles and flow, verify coldest relevant history and recovery, and document uncertainty, limits, diversion and change triggers. Verify calibrated temperature, flow, pressure, timing and diversion under approved cases, then document residence distribution, fouling response, cleaning, energy recovery and product outcomes. 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.
