04 / Acceptance and handover
Prove the result under a representative production condition
Challenge low inlet pressure and startup safely, trend vibration, pressure and seal condition, and verify interlocks, no air or contamination, stable performance and maintenance baseline. 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.
