If a customer specifies that an Inspection Certificate in accordance to EN 10204 3.1 is required for a machined component, example a manifold, this is how the process would work, correct Raw Material and a Material Mill Test Report EN 10204 3.1 would be procured by the Machine Shop.

After receipt, the machine shop would perform the necessary machine shop operations per the customers specifications drawings.

The machine shop would then generate its own Inspection Certificate in accordance to EN 10204 3.1.

The machine shop would then copy and include the information provided on the original MTR onto that certificate and send it to the customer I am not exactly sure what other Test Results could be included on the Machine Shops Inspection Test Certificate.

With the information that I have read, I just wanted to make sure I understand the process correctly.

You would supply the machine shops inspection results on the cert and the original mill test results.

If the product that is being supplied is a machined component, could the machine shops inspection results just be a statement that the dimensions verified are in accordance to the applicable print I am not sure what all would need to be included in the machine shops inspection results that would be on the certificate.

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.

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.
