Why Buyers Search for an MTC Template
Many buyers search for an "MTC 3.1 template" because they want to know whether a supplier's certificate is complete. The safer approach is not to copy a sample certificate. A sample can be fake, outdated, or unrelated to your product. Instead, use a field checklist based on the purpose of EN 10204 inspection documents.
Public summaries of EN 10204 describe it as a standard for types of inspection documents for metallic products. For pipe fittings and flanges, the certificate must help the buyer connect the delivered product to the order, material grade, heat number and required test results.
Core Fields to Check
For an EN 10204 3.1 MTC, buyers should normally check these fields:
| Field | Why it matters |
|---|---|
| Supplier / manufacturer name | Confirms who issued the document |
| Buyer / purchase order number | Connects the certificate to the order |
| Product description | Confirms fitting type, flange type, size or wall thickness |
| Material standard and grade | Example: ASTM A234 WPB, ASTM A350 LF2, ASTM A105N |
| Heat number or batch number | Links the certificate to product marking |
| Chemical analysis | Verifies material composition against the required standard |
| Mechanical properties | Verifies tensile, yield, elongation or impact tests when required |
| Heat treatment | Important for low-temperature, normalized or quenched-tempered products |
| NDT or supplementary test results | Required when the PO or project specification asks for it |
| Signature / stamp / issue date | Confirms the document was formally issued |
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.
