Traceability for EN 10204 3.1 certificate 1

[metboss]

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 ??

3.1 needs to mention a heat (lot / schmeltz / batch / ...) number.
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.

If any processing has been done after the heat left the mill (cold work, heat treat or such) then it must identify those items also and whatever control lot was used for them.
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.

Thanks gents for your valuable input.

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 ??

Regards

Not in the EN10204, but rather in the other codes that refer to 10204, like for example the EN1090.
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.

Yes, see chapter 6. Your mention of EN 1090 sheds a whole new light on this subject.

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;

that the products supplied are in compliance with the requirements of the order

It is the responsibility of the manufacturer to determine what has to be on the MTR.
