04 / Acceptance and handover
Prove the result under a representative production condition
Use representative material lots and line-applied packs and verify bond, aging, removal and lifecycle compatibility. Retain measured evidence for adhesive identity and construction and bond, aging and recycling proof with method, conditioning, limit, deviation, witness, approval and review trigger. Run approved material lots and artwork at representative surface and speed conditions, challenge wrong and unreadable identity, verify position, adhesion, shrink, scuff and code quality, test reject security and reconcile materials and serialized or lot data where applicable. 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.
