DOCUMENTATION: UNI EN 10204, UNI EN ISO 16228 CERTIFICATES
In the field of mechanics and industrial production, technical documentation plays a fundamental role. It includes certificates and specifications that ensure the conformity of materials and processes to international standards. Among the main normative references are UNI EN 10204 and UNI EN ISO 16228.
UNI EN 10204
The UNI EN 10204 standard specifies the types of inspection documents for metallic products. It is essential to guarantee the traceability and quality of the materials used in production.
Types of Certificates according to UNI EN 10204
2.1 Declaration of conformity: Provided by the manufacturer, it declares that the products supplied comply with the order requirements.
2.2 Manufacturer's test report: Includes test results not specified in detail.
3.1 Test certificate: Issued by the manufacturer, with tests performed on representative products.
3.2 Validated test certificate: 3.1 certificate validated by a third-party body.
Table of UNI EN 10204 Certificates
CERTIFICATE TYPE | ISSUED BY | VALIDATION |
---|---|---|
2.1 | Manufacturer | None |
2.2 | Manufacturer | Internal to manufacturer |
3.1 | Manufacturer | Internal inspection body |
3.2 | Manufacturer and third party | External inspection body |
UNI EN ISO 16228
The UNI EN ISO 16228 standard defines the requirements for documenting quality controls and test procedures in production processes. It is crucial to ensure that final products meet the required technical and quality specifications.
Specifications of UNI EN ISO 16228
- Test Procedures: Describes standardized test methods for verifying material properties.
- Documentation of Results: Requires detailed recording of test results.
- Conformity to Requirements: Establishes acceptance criteria based on test results.
Importance of Documentation
Technical documentation and conformity to standards such as UNI EN 10204 and UNI EN ISO 16228 are essential for:

- Traceability: Ensure the traceability of materials used.
- Quality: Improve the overall quality of products.
- Reliability: Increase the reliability of production processes.
