Documentation
EN 10204 certificate types
If a specification simply says 'with certificate', it is worth confirming which one. The difference between a 2.2 and a 3.1 is the difference between a report and traceability.
2.1
Declaration of compliance
Statement of compliance with the order, no test results
Commodity fixings, non-structural
2.2
Test report
Non-specific test results from the manufacturer
General purpose fasteners
3.1
Inspection certificate
Specific test results, validated by the mill's independent inspector, tied to the heat
MST standard for structural and pressure-retaining supply
3.2
Witnessed inspection certificate
Specific results countersigned by a third-party or client inspector
Critical service, client-mandated witness points
