thread367-234594: Content of 2.2 certificate EN10204
We got some strange COA EN 10204 2.2 type lately for some S 235 sheets.
The strange is, they don't contain any mechanical test report, only chemical analysis.
Question: Where can I find out if mechanical test reports are a must or not for COA 2.2 EN 10204.
Hope the question is clear, and also hope some of you can help me!
Thanks!

Csike

I have sometimes seen in 2.2 certificates yield and tensile values but quite rarely.
Note that also for quality S 235 which is considered as "basic" steel quality, the majority of steel producers would not "bother" mentioning mechanical values especially in sheet/plate form.
In answer to your question I don't think that mech. test reports are a must for 2.2 EN 10204 cert.
This type of certification is based on non specific inspection (tests).

But the material standard often gives requirements concerning the content. I assume your delivery was according EN 10025-2.
Appendix B of EN 10025-1 is only applicable for the evaluation of conformity, to be submitted to the certification body. Appendix B can not be applied for a particular delivery of sheets.
But in para 8.2.1 of EN 10025-1: "The manufacturer shall obtain from the purchaser which of the inspection documents specified in EN 10204 is required. In these inspection documents the information groups A, B, D and Z and the code numbers C01-C03, C10-C13, C40-C43 and C71-C92 according EN 10168 shall be included where applicable."
C10-C13 concerns the tensile test tesults, C40-C43 concerns the impact results. If you order a 2.2 certificate, you have the right to obtain values from tensile testing and eventually for impact testing if your thickness is >= 6mm.
Another question is, how helpful and how representative values from current production are in reality for your actual delivery. In the 2.2 certificate the manufacturer declares that the products supplied are in compliance with the requirements of the order. This is sufficient for the use of the material in European Construction Codes. If you need more precise details, you should order a 3.1 certificate.

Thanks for all of you for the valuable comments!
It seems clear now, mech test report (and as I understand even the chemical analisys report) is not a must of the 2.2. certificates, unless it is not stated in the orders.
Interesting, isn't it?
