EN 10204 certificates explained.
EN 10204 defines four inspection documents for metallic products. Types 2.1 and 2.2 come from the manufacturer without lot-specific testing; 3.1 reports tests on the delivered lot, validated by an independent inspection representative; 3.2 adds the purchaser's or an official inspector's validation.

Questions buyers ask.
What is the difference between EN 10204 3.1 and 3.2?
Both report tests on the delivered products. A 3.1 certificate is validated by the manufacturer's authorised inspection representative, independent of manufacturing; a 3.2 is validated by that representative and by the purchaser's representative or an inspector named in official regulations.
Can a 2.2 test report be upgraded to 3.1 after delivery?
No. The document type must be agreed in the order, because a 3.1 or 3.2 depends on specific inspection of the lot before it ships.
