Inspection evidence comparison
Bronze Evidence Object Comparison Builder
Choose an evidence object and an order decision to see whether they match. The builder separates material identity, process history, measured geometry, and acceptance authority so one document is not asked to prove everything.
Evidence objects are not interchangeable
| Evidence object | Can support | Cannot replace | RFQ field to state |
|---|---|---|---|
| Material record | Identity and values explicitly covered by the document | Finished dimensions, surface condition, or service life | Standard, grade, lot link, test basis, and required fields |
| Test-bar result | Results for the standard-defined sample and conditions | Every local property or defect state in the finished casting | Applicable specification, sampling basis, and acceptance rule |
| First-article report | Named characteristics on the identified sample and revision | Automatic acceptance of every later production unit | Feature list, method, state, sample identity, and approval hold |
| Batch report | Recorded results for the stated features, sample plan, and lot | Unmeasured features or unstated functional performance | Coverage, frequency, lot identity, method, and disposition |
| Process record | Completion of the named process under the stated scope | Unrelated dimensions, material identity, or service approval | Process specification, revision, provider, certificate, and acceptance |
| Photograph | Visible equipment, geometry, quantity, or machining stage | Alloy, hidden defects, tolerance, pressure integrity, or capability | Use photos as context, then request order-linked records |

Release wording
Result boundary: this comparison helps name an evidence gap. Final acceptance remains governed by the controlled drawing, purchase specification, applicable standard, and agreed inspection plan.
