Traceability for EN 10204 3.1 certificate
Traceability for EN 10204 3.1 certificate
(OP)
Hi all
We have requested our vendor to supply some drilling accessories with 3.1 certificates. However, vendor acknowledged the same to provide 3.1 certificates (chemical & mechanical properties); but without any traceability. My question is whether traceability is mandatory for 3.1 certificates or not ??
Regards

When you have that (and the manufacturer), you can go back to the source of the steel.
That's how one usually interprets traceability to my knowledge. I could be wrong though.
RE: Traceability for EN 10204 3.1 certificate
If the person providing the certificate did not do the work (make the material) then they should either identify the source or provide copies of the original certificates. Passing through information (such as chem) without identifying the original source is bad form.

Kingnero, I referred EN 10204 and as per this specs, regarding traceability, no clause found as mandatory for traceability. Only mentioned as "It shall be permissible.........".
Could you please let me know as per which clause, traceability is mandatory ??

With a heat number, you have your traceability.
Unless, as EdStainless mentions, it has been processed afterwards, but in that case, the "processor" should make his own declaration of performance or similar form that mentions the properties of his finished product, and delicir it together with the product..
This is, following EN1090, a necessity.
RE: Traceability for EN 10204 3.1 certificate
EN 10204 is strictly for material certificates, and, as pointed by kingnero, obviously requires that materials are identified (otherwise, whats the use of th MTR?).
However, EN 1090 may set additional requirements to traceability. As such, it is the obligation of the manufacturer of the structure being affixed with the CE-marking, to assure all traceability is properly documented. See e.g. EN 10204:2004 para 4.1 first sentence;
It is the responsibility of the manufacturer to determine what has to be on the MTR.
