What does an EN 10204 3.1 certificate prove?
It documents conformity with the order requirements and reports test results for the supplied material.
Is an MTR the same as a PED certificate?
No. The MTR is material evidence; PED conformity depends on the applicable pressure-equipment assessment and documentation.
