04 / Acceptance and handover
Prove the result under a representative production condition
Map concentration and endpoint through minimum and maximum batches, verify circulation and coverage, and document selected route, cycle, heel, temperature, access and cleaning evidence. 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.
