04 / Acceptance and handover
Prove the result under a representative production condition
Review thermal and flow rationale, inspect as-built placement, compare mapped response under boundary flow, and verify immersion, lag, calibration, diversion timing and hygienic condition. 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.
