Certifications: the certificate with every delivery and the system behind it

In automotive and in precision industry, conformity is not a commercial promise: it is a document. We deliver every tubing with its EN 10204 certificate, with full material traceability and the backing of our in-house laboratory at the plant. Here we explain what we certify, how and with what guarantee.

01

The three layers of the process

When a buyer asks for "certified tubing", three distinct and complementary things are actually in play:

The product standardDefines what the tubing is (dimensions, tolerances, process, material). It is the reference we manufacture against: EN 10305, ASTM A513, SAE, JIS.
The certification documentProves that the tubing you received meets that standard. It does not describe the product: it certifies the delivered batch and guarantees its traceability. It is the EN 10204 standard (certificates 2.2 and 3.1).
The system certificationCertifies that the company manufactures under an audited management system (quality, automotive, environment). It does not certify the tubing or the specific batch, but the processes by which it is made.

A tubing is made to a product standard, is delivered with an EN 10204 certificate and leaves a plant with a certified system. The three layers, together, are the complete guarantee.

03

How we back every certificate: in-house laboratory

A certificate is only worth as much as the controls behind it. Ours are done at the plant, in our own laboratory, so the certificate carries real batch data, not generic values:

Dimensional controlsOf outer diameter, bore and wall thickness, during and after manufacture.
Mechanical property testsTensile strength, hardness and material behaviour.
Application-specific testsTightness, strength and whatever tests the part requires.
Full traceabilityOf the material, from batch to heat.

The in-house laboratory is what lets us respond technically to any incident, with the data in hand.

Management system certifications

Beyond the document for each delivery, system certifications attest that all our manufacturing is governed by processes audited by an external body. It is the guarantee that what you receive today is made the same way as what you receive in a year's time.

Each certification has its own page, explaining what it attests and what it means for you.

In-house laboratory at the plant that backs every figure with real batch controls.
Full traceability of the material.
Honest about scope: we certify what we can demonstrate; we do not attribute to the company or the product certifications that are not current.
