The final dossier should not be a loose collection of certificates. A document index agreed before production identifies which records are required, who reviews them and how each file links to the order and product identity.
Material certificates typically record product designation, heat identity, chemical composition, mechanical results and applicable specification.
Depending on product and scope, the dossier may include dimensional reports, NDT results, hydrostatic testing, hardness, impact testing, thread gauging, coating inspection and final visual checks.
Heat, lot and item identification should remain readable and connected to the packing list and certificate package.
