QUALITY & PROCUREMENT GUIDE
Building an Inspection Scope Buyers Can Use
A useful inspection scope identifies what must be verified, when it is verified, who participates, what criteria apply and which record proves completion.
Start from the governing requirements
Inspection activities should be traceable to product standards, purchase specifications, approved drawings and agreed technical clarifications.
- Applicable standard and edition
- Purchaser and project clauses
- Approved drawings and data sheets
- Clarifications, deviations and acceptance basis
Build the ITP around the route
The inspection and test plan should follow the actual manufacturing sequence and identify review, witness and hold points at stages where evidence can still be obtained.
- Material receipt and traceability
- Critical process and heat-treatment stages
- NDT, mechanical and pressure testing
- Final dimensions, marking and packing
Define evidence before production
Report format, traceability fields and document approval should be agreed early so the final dossier is not reconstructed after manufacture.
- MTC and heat traceability
- Test and inspection reports
- Nonconformity and concession records
- Certificate and release documents
Separate surveillance from acceptance
Mill inspection, OAK coordination and third-party participation may perform different roles. The purchase order should make responsibility and release authority clear.
- Inspection responsibility matrix
- Notice periods and access conditions
- Witness waiver and missed-point rules
- Final release and shipment authorization
