04 / Acceptance and handover
Prove the result under a representative production condition
Trend inlet, outlet and tank temperatures through worst duty, calculate energy balance, and compare product attributes while verifying cooling capacity, alarm and maximum exposure. 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.
