When your quality assurance team, an external auditor, or your industry requires verification of exactly what a part is made of, a material certificate is the document that supplies it.
What an MTC is
A Material Test Certificate records a material's chemical composition and mechanical properties, then ties your part back to the specific heat or batch it was cut from.
The EN 10204 types
| Type | What it certifies | Validated by |
|---|---|---|
| 2.1 | Compliance statement, no test data | Manufacturer |
| 2.2 | Test report, non-specific (typical) data | Manufacturer |
| 3.1 | Actual test results for your batch | Manufacturer (most-requested) |
| 3.2 | 3.1 results, witnessed independently | Independent inspector |
How we handle it
We buy certified stock, verify it on arrival, and keep full batch traceability throughout. That lets us issue an EN 10204 3.1 / MTC on request with your order.
When you need it
Aerospace, automotive, and medical QA; customer audits; and any program that requires traceability. When an auditor reviews a 3.1 cert, they verify the physical chain: the heat or batch number on the certificate must match the number on the job traveler and on the packing slip, the same number all the way through.
Two quick mistakes
- Requesting a cert after production. Traceability must be built into the stock before machining; it cannot be added retroactively.
- Asking for 2.2 when your audit actually needs 3.1. Confirm which type your requirement calls for before you request it.
