Requirement review
Drawing revision, material, tolerances, test standards, acceptance criteria, and document language.
Quality planning
Manufacturing quality control built around the purchase specification
Inspection is most useful when acceptance criteria, records, and hold points are agreed before production—not added after the parts are finished.
Inspection plan
Define the evidence your team needs
Available inspection and documentation depend on the part, process, supplier route, order value, and applicable standard. Requested records should be listed in the RFQ so feasibility and cost can be confirmed in the quotation.
Material control
Specified material certificates, traceability method, positive material identification, or mechanical testing when required.
In-process checks
First-piece or stage inspection at the manufacturing points where later verification would be difficult.
Dimensional inspection
Critical dimensions, measuring method, sampling plan, and report format agreed for the order.
NDT or functional testing
PT, MT, UT, RT, pressure, leakage, hardness, balance, or fit checks only where applicable and specified.
Release and packing
Final record review, identification, corrosion protection, packing, shipping marks, and document handover.
Common records to specify in an industrial RFQ
| Record | When it may be relevant | Confirm in RFQ |
|---|---|---|
| Material certificate | Critical alloy or pressure/wear service | Grade, standard, type, traceability |
| Dimensional report | Drawing-controlled and mating features | Dimensions, sampling, report format |
| NDT report | Castings, forgings, welds, or critical surfaces | Method, extent, procedure, acceptance |
| Pressure or leakage record | Pressure-containing parts and sealing assemblies | Medium, pressure, duration, acceptance |
| Hardness / heat treatment | Gears, shafts, wear parts, alloy components | Location, range, case depth, charts |
| Certificate of conformity | Project closeout or distributor records | Referenced order, drawing, standard |
Certificates, test methods, third-party inspection, and specific quality-system requirements are not assumed. Request them before quotation so the applicable manufacturing route can be checked and documented.
Acceptance planning
Quality and inspection questions
Does an NDT report prove that a component is defect-free?
No. An NDT report records the method, examined area, technique, sensitivity, indications, and acceptance decision against defined criteria. Its conclusion is limited to that scope and does not guarantee every possible discontinuity or overall fitness for service.
When should third-party inspection be requested?
Request it when the purchase specification, project risk, customer contract, or regulatory plan requires an independent witness or review. Define the agency, hold or witness points, document access, notice period, and release authority in the RFQ.
What should a material certificate be traceable to?
The required chain depends on the order, but the RFQ should connect the material record to the ordered item through heat, batch, part, or other agreed identification and state how identification is preserved through cutting and machining.
Can inspection requirements be added after production?
Some checks may remain possible, but late requirements can be impractical, destructive, or unable to reconstruct earlier process evidence. Define acceptance criteria, sampling, hold points, and records before quotation and production.
