How to verify a certificate
The certificates shown are scans of the originals, and each section names the mill that holds them. To verify independently, contact the classification society with the certificate number on each card. Every society keeps its own register of approved manufacturers.
EN 10204 3.1 vs 3.2
Every shipment is accompanied by a mill test certificate (MTC) reporting the actual chemistry and mechanical test results for that heat. EN 10204 defines two relevant certificate types:
- Type 3.1
- Issued and validated by the manufacturer's own authorized quality department — the standard form for most commercial shipments.
- Type 3.2
- Adds independent countersignature by a third-party inspector — typically the classification society surveyor — confirming the results. Used when the buyer's contract or classification society requires third-party witnessed inspection.
Mill test certificate contents
The MTC lists the heat number, chemical composition, and mechanical test results (ReH, Rm, elongation, and Charpy impact where required) for the specific heat your plate was rolled from. It is a separate document from the works approval certificates above: works approval certifies that the mill is qualified to produce a grade, while the MTC reports the actual results for one shipment. A sample MTC is not shown, because a real certificate carries a specific heat number and buyer details; every shipment is accompanied by the MTC for its own heat.
