04 / Acceptance and handover
Prove the result under a representative production condition
Verify counts or length conversions, secure returns and destruction, and investigate differences before order closure. Retain measured evidence for issued roll, sheet or sleeve quantity and variance, investigation and closure 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.
