Quick Answer
The EN 10204 certificate checker is a free, no-login web tool that reads a single mill test certificate (MTC) — pasted as text or uploaded as a text-based PDF — and answers two questions: which EN 10204 inspection-document type the certificate is (2.1, 2.2, 3.1, or 3.2), and whether it carries the fields such a certificate should have (heat/cast number, chemical composition, mechanical properties, governing standard reference, and inspector sign-off). It classifies and checks for field presence only; it does not validate chemistry or mechanical values against a standard, decide pass/fail, or extract structured data — those are reserved for the paid TestCert product.
Paste or upload a mill test certificate below. In seconds, find out whether it's a 2.1, 2.2, 3.1, or 3.2 under EN 10204 — and whether it carries the fields it should: heat number, chemical composition, mechanical properties, standard reference, and inspector sign-off. Free, no login, one certificate at a time.
EN 10204 Certificate Checker
Paste or upload one mill test certificate to identify its EN 10204 type and check for the expected fields.
Why certificate type matters
Certificate type matters because a purchase order that specifies an EN 10204 3.1 inspection certificate is not satisfied by a 2.2 test report — the difference is who validates the material certification, and getting it wrong is one of the most common incoming-inspection findings in metals fabrication and distribution.
- 2.1 — Declaration of compliance with the order. No test results.
- 2.2 — Test report. The manufacturer's own test results, non-specific inspection.
- 3.1 — Inspection certificate validated by the manufacturer's authorized inspection representative, independent of the manufacturing department.
- 3.2 — Inspection certificate validated additionally by the purchaser's representative or an independent third party, alongside the manufacturer's representative.
This tool reads your mill test certificate and tells you which type it appears to be — with the evidence it found — so you can confirm it against your PO before it enters your quality system.
What the EN 10204 types mean
The four EN 10204 inspection-document types differ by two things: whether the certificate reports actual test results, and who validates those results. The table below summarizes the practical distinction a Quality Manager needs at incoming inspection.
| Type | Name | Test results? | Validated by |
|---|---|---|---|
| 2.1 | Declaration of compliance with the order | No test results | Manufacturer, no results reported |
| 2.2 | Test report | Yes, non-specific | Manufacturer, on the basis of non-specific inspection |
| 3.1 | Inspection certificate | Yes, specific to the product | Manufacturer's authorized inspection representative, independent of the manufacturing department |
| 3.2 | Inspection certificate | Yes, specific to the product | Manufacturer's representative and the purchaser's representative or an independent third party |
The key line to remember: a 2.1 carries no test results, a 2.2 carries the manufacturer's own non-specific results, a 3.1 carries specific results validated by an inspection rep independent of production, and a 3.2 adds a second, independent validation.
How it works
The tool runs in four steps — add the certificate, identify the type, check the fields, and read the verdict.
- Add your certificate — paste the certificate text, or drop in a text-based MTC PDF.
- The tool identifies the type — it scans for EN 10204 type markers and structure, then reports 2.1, 2.2, 3.1, or 3.2, and shows the snippets that led to the call.
- The tool checks the expected fields — a five-point checklist flags whether the certificate contains a heat/cast number, chemical composition, mechanical properties, a governing standard reference, and an inspector or authority sign-off.
- You get a clear verdict — a plain read on document type and field completeness you can act on before the certificate enters your QMS.
What this free tool does — and doesn't
This free tool is a classifier and checklist, not a validator: it identifies the EN 10204 document type and confirms that key MTC fields are present, and nothing more.
It does: identify the EN 10204 document type and confirm that key MTC fields are present.
It doesn't: validate your chemistry or mechanical values against a standard, decide pass/fail, extract structured data into your system, or read scanned PDFs with no text layer. Those are jobs for TestCert.
Classification is heuristic — always confirm the certificate type against your purchase order. Field checks confirm presence, not correctness.
When "present" isn't enough
This checker tells you a field exists; it can't tell you whether the values pass, and it can't pull the data into your system — that is where the paid TestCert product takes over.
TestCert is mill test certificate data extraction and validation software. It reads your supplier MTC PDFs with AI extraction, pulling the chemistry, mechanical properties, and header data with confidence scores you can review and edit, then validates every row Pass / Fail / Borderline against a versioned library of ASTM, ASME, EN, API, and IS standards. Certificates can arrive automatically by email, route through your approval chain, and feed heat-number traceability — end to end.

What does the EN 10204 certificate checker do?
The EN 10204 certificate checker is a free web tool that reads one mill test certificate — as pasted text or a text-based PDF — and returns two things: the EN 10204 document type (2.1, 2.2, 3.1, or 3.2) with the evidence behind the call, and a five-point presence check for heat number, chemistry, mechanical properties, standard reference, and inspector sign-off. It classifies and checks presence only; it does not validate values.
What is EN 10204?
EN 10204 is the European standard that classifies the types of inspection documents a metal-product manufacturer can issue for a delivery. It defines four types — 2.1, 2.2, 3.1, and 3.2 — distinguished by whether the certificate reports actual test results and who validates them, from a simple declaration of compliance up to inspection validated by an independent third party.
What's the difference between a 3.1 and a 3.2 certificate?
A 3.1 inspection certificate reports specific test results validated by the manufacturer's authorized inspection representative, who must be independent of the manufacturing department. A 3.2 adds a second validation: the certificate is also endorsed by the purchaser's representative or an independent third party. Both report specific results; 3.2 carries the extra independent sign-off some contracts require.
Is a 2.2 the same as a mill test certificate?
A 2.2 is a test report carrying the manufacturer's own test results on the basis of non-specific inspection — it is one kind of mill test certificate, but not the strictest. Many purchase orders require a 3.1 instead, which adds validation by an inspection rep independent of production. Always check what type your purchase order calls for before accepting a 2.2.
Can this tool extract the data from my certificate?
No. The free checker only identifies the certificate type and confirms which fields are present; it does not pull values into your system or read scanned image PDFs.
