04 / Acceptance and handover
Prove the result under a representative production condition
Verify air quality, filter installation, pressure behavior, sanitation and maintenance under fill, empty and idle states. Retain measured evidence for tank breathing flow and pressure range and sanitation, monitoring and replacement with method, state, limit, deviation, witness, approval and review trigger. Use qualified preservation evidence, controlled product and environmental sampling, hygienic-design and airflow review, container and closure challenges, stop and restart trials, cleaning verification, sealed-pack integrity and representative real-time shelf study. 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.
