What is EN 10204?
EN 10204 defines the different types of inspection documents used to verify conformity, quality control and material traceability for metallic products and pressure equipment. The standard does not define material properties but rather how inspection and testing results are documented and communicated to customers.
Applications of EN 10204
- Industrial valves
- Steam traps
- Safety valves
- Control valves
- Heat exchangers
- Pressure vessels
- Process piping
- Pipe fittings
- Marine applications
- Power generation plants
- Chemical and petrochemical facilities
EN 10204 Certificate Types
EN 10204 Type 2.1
A declaration of compliance stating that the supplied product meets the order requirements. No test results are included.
EN 10204 Type 2.2
A test report providing general inspection results not necessarily linked to the specific production batch.
EN 10204 Type 3.1
The most commonly requested certificate in industrial applications. Inspection results are linked directly to the supplied batch and validated by an independent quality department.
EN 10204 Type 3.2
Includes all information provided in a Type 3.1 certificate together with independent verification by a third-party inspection body or customer representative.
Comparison of EN 10204 Certificates
| Certificate Type | Test Results | Traceability | Independent Verification |
|---|---|---|---|
| 2.1 | No | No | No |
| 2.2 | General Results | Limited | No |
| 3.1 | Yes | Full | No |
| 3.2 | Yes | Full | Yes |
Material Traceability
Material traceability links a component to manufacturing records, material suppliers, production batches and inspection results through heat numbers, cast numbers and serial numbers.
Relationship with PED 2014/68/EU
EN 10204 is widely used together with the European Pressure Equipment Directive (PED). The required certificate type depends on project specifications, equipment category and end-user requirements.
