Types of Inspection Certificates under DIN EN 10204
One of the core components of DIN EN 10204 is the classification of inspection certificates, which are categorized based on the depth of testing and information provided. These certificates are designated by the number following the "Type" (e.g., Type 2.1, 2.2, 3.1, 3.2, etc.).
Type 2.1: Material Test Report by Manufacturer
- Description: A basic certificate issued by the manufacturer or their authorized agent.
- Contents:
- Basic material identification
- Confirmation of compliance with specified standards
- Test results (e.g., chemical composition, mechanical properties)
- Limitations:
- No independent verification
- Typically used for internal quality assurance or less critical applications
Type 2.2: Inspection Certificate with External Inspection
- Description: An inspection document issued and signed by the manufacturer, but verified by an independent inspector or authorized third party.
- Contents:
- Similar to Type 2.1 but with added verification
- Ensures increased confidence in the test results
- Use Cases:
- When customer demands verification beyond internal testing
- For purchase orders requiring third-party oversight
Type 3.1: Inspection Certificate with Witnessed Tests
- Description: A detailed certificate issued after tests are witnessed by an authorized inspector.
- Contents:
- Detailed test data
- Witnessed testing process
- Signatures of manufacturer and inspector
- Features:
- Higher level of assurance
- Suitable for critical applications
Type 3.2: Certification with Independent Testing
- Description: The highest level of certification under DIN EN 10204, issued after tests are performed by an independent laboratory.
- Contents:
- Comprehensive test results
- Evidence of independent testing
- Full traceability
- Use Cases:
- Aerospace, nuclear, and other high-criticality industries
