Engineering basis

Purchase specifications should define standard/edition, grade, product form, dimensions, tolerances, delivery condition, impact requirements, NDT, coating, marking, MTC type and approved manufacturer.

Standards, grades or methods

Critical projects may also require approved vendor lists, ITPs, third-party inspection, manufacturing procedure qualification, origin restrictions or additional testing.

Typical applications

Construction, EPC, oil and gas, district cooling, power, marine and industrial maintenance procurement.

Critical checks

Separate manufacturer from trader/stockist, verify origin, confirm heat traceability, control substitutions, review certificates before release and define document dossier requirements in the PO.

Good engineering practice

Use the current governing code or specification and verify manufacturer data, material traceability and project-specific requirements. Where safety, pressure containment or structural integrity is involved, obtain approval from the responsible engineer before changing material, process or acceptance criteria.
