04 / Acceptance and handover
Prove the result under a representative production condition
Audit and challenge the closure route and verify treatment, environment, application, inspection and stop response. Retain measured evidence for closure packaging and supplier condition and application, inspection and hygiene proof 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.
