EN 10204 3.1 Certification Vs EN 10204 3.2 Certification

Looking for an EN10204, 3.2 Certification?
EN10204 is a Euronorm (issued by the European Community) specification that describes different types of material test reports and certifications. The standard contains no requirements relative to actual material requirements. The most common reference is to a 3.1 type certification (3.1 is the paragraph number within EN10204 that describes the content). A 3.1 certification is simply the common mill test report that reports test results on the lot of material in question, performed by a laboratory (often operated by the mill itself) that is independent of the personnel actually producing the material. Sending samples to an independent laboratory for testing to the ordering specifications will still result in a 3.1 certification. It is just being tested by a second source.
EN10204 defines a 3.2 certification as a:
“Document prepared by both the manufacturer’s authorized inspection representative, independent of the manufacturing department and either the purchaser’s authorized representative or the inspector designated by the official regulations and in which they declare that the products supplied are in compliance with the requirements of the order and in which test results are supplied”.

I have contacted several European Authorized Bodies in the US that provide 3.2 certifications. All responded by saying that a true 3.2 certification is not possible for material that is stocked to commercial standards without a 3.2 certification issued by the mill at the time of delivery. Their interpretation is that only a mill can issue a true 3.2 certification. They can do so when the testing has been witnessed at the mill by an Authorized Body.
