What to know before ordering to EN 10204
The points that decide whether material to EN 10204 is accepted at inspection.
- 3.1 is issued by the manufacturer's inspection department, independent of production, with actual test results.
- 3.2 is countersigned by an independent inspector or the purchaser's representative.
- Ask for 3.2 at enquiry stage — it adds inspection time and cost.
How EN 10204 fits into an order
A purchase order line is only complete when it names the material standard, the dimensional standard and the inspection document. Miss one and the mill, the inspector and the buyer can each read the order differently.
