MTC 3.1 Certificate Template Fields: What Buyers Should Check Under EN 10204

For an EN 10204 3.1 MTC, buyers should normally check these fields:

This is not a fake certificate template. It is a buyer's review structure.

What 3.1 Does Not Solve Alone

A 3.1 certificate does not automatically prove that every project requirement has been met. The buyer still needs to compare the MTC with the purchase order, product standard, drawing, inspection plan and final client specification.

If the project requires independent witness or validation, the buyer may need EN 10204 3.2 or a separate third-party inspection report. SGS Japan's EN 10204 3.2 material certification page is one public example showing that 3.2 certification involves an inspection body role.

Common Red Flags

Be careful when you see:

• Heat number on MTC does not match product marking
• Standard or grade is missing
• Certificate says only "quality certificate" without EN 10204 type
• Chemical or mechanical test values are blank
• The product description does not match the ordered item
• The MTC is for mother pipe only, while the delivered item is a formed fitting
• NDT is mentioned in the quotation but no report is attached

How to Write the Requirement in an RFQ

A clear RFQ can say:

"Supplier shall provide EN 10204 3.1 material test certificate for each heat/batch. MTC shall show purchase order reference, material grade, heat number, chemical analysis, mechanical test results, heat treatment where applicable, product description and traceability to product marking."

If a third party must be involved, state that separately. Do not assume 3.1 and 3.2 are interchangeable.
