Define acceptance.
Before production.
A custom component needs agreed acceptance criteria. The drawing and quotation should identify what matters, how it will be checked, and which documents are required.
Explore material families, grades and documentation requirementsTurn the drawing into an inspection brief.
The following requirements help define your project. Inspection scope and documentation are agreed for the order; they should not be assumed from a general product description.
| Requirement | What to specify | What to agree for acceptance |
|---|---|---|
| Material | Grade, sheet or wall thickness, and any required traceability. | Material documents or batch identification, where requested and agreed. |
| Cut geometry | Critical feature sizes, hole positions, cut edges and fit requirements. | The dimensions and edge conditions to inspect. |
| Formed features | Bend angle, radius, flange dimensions and reference surfaces. | Acceptance measurements on the finished formed part. |
| Surface finish | Cosmetic faces, burr restrictions, surface treatment and protective requirements. | The surface condition or reference sample to use for acceptance. |
| Packing & delivery | Marking, separation, surface protection and packaging requirements. | The agreed packing specification and shipment documentation. |
Critical features
need explicit tolerances.
Do not use an overall dimension or a visual preview as a substitute for the tolerance needed at an assembly interface.
- Drawing revision
- Identify the approved revision and units to use for manufacturing and inspection.
- Fit & assembly
- Highlight mating holes, datum relationships, clearances and surfaces that affect the function of the part.
- Records
- Tell us if your purchase requires dimensional records, material documentation or another agreed inspection deliverable.
