EN 10204-2.2 and 3.1 certificates: the document that comes with every delivery
The certificate is not an optional document or an extra on request: it is our delivery standard. Every order leaves the plant with its EN 10204 certificate, with real batch data and full material traceability.

What the EN 10204 standard is
EN 10204 is the European standard that defines the types of inspection documents the manufacturer supplies to the customer together with metallic products. It does not describe the tubing: it sets out what information accompanies the batch and who validates it, so the buyer knows exactly what has been checked and with what guarantee.
It is the document that links the product standard to the material arriving at your plant: the tubing is manufactured to its standard (EN 10305, ASTM A513, SAE, JIS) and the EN 10204 certificate proves that the batch you have received complies with it.
The two certificates we issue
| An | What it attests | When it is used |
|---|---|---|
| EN 10204-2.2 | Declaration of compliance with the order, with non-specific inspection results. | Standard certificate for every delivery, when no tests on the specific batch are required. |
| EN 10204-3.1 | Inspection certificate with test results for the supplied batch, validated by an inspection representative independent of manufacturing. | Automotive and critical applications, when your quality system requires batch data. |
We issue the certificate your quality system requires, and for distributors we can issue it to the specific standard their homologation process requires, regardless of the destination market.
What every certificate includes
Every certificate identifies the batch and documents, with real data, what was manufactured and checked:
How we back every certificate: in-house laboratory
A certificate is only worth as much as the controls behind it. Ours are carried out at the plant, in our in-house laboratory: dimensional checks during and after manufacture, tensile and hardness tests, and whatever tests the application requires. That is why the certificate carries real batch data, not generic values, and why we can respond technically to any incident with the data in hand.
