04 / Acceptance and handover
Prove the result under a representative production condition
Verify routing and chemical conditions, inspect or sample risk-ranked hidden surfaces after worst soil, and demonstrate residue removal, drainage, rinse endpoint, reassembly and release. 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.
