EN 10204 Material Certification Explained — Type 2.2, 3.1 and 3.2 Inspection Documents Compared
A technical guide to EN 10204 material inspection documentation — the difference between 2.2 test reports, 3.1 certified test reports, and 3.2 third-party witnessed certificates, who is qualified to issue each type, and how to correctly specify the right certification level for your forged component project.

EN 10204 is the European standard governing the types of inspection documentation that can accompany metallic material supply, and its core distinction — the difference between document types 2.2, 3.1, and 3.2 — comes down to a single critical question: who is validating that the documented test results are accurate, and how independent is that validation from the manufacturer itself? A 2.2 test report is issued by the manufacturer based on non-specific testing (not necessarily from the actual batch supplied) with no independent validation. A 3.1 certified test report is issued by the manufacturer's own authorized quality department, based on specific testing of the actual material supplied, with the manufacturer's quality function independent from the manufacturing function attesting to compliance. A 3.2 certificate adds a further layer: validation and countersignature by a customer-nominated third-party inspector (or the purchaser's own authorized representative) independent of the manufacturer entirely, witnessing the actual testing or independently validating the results — a meaningfully higher assurance level reserved for the most critical applications.
A document issued by the manufacturer stating test results based on non-specific testing — meaning the tests may be representative of the production method rather than necessarily performed on the exact batch supplied — without independent validation from a quality function separate from manufacturing.
A document issued by the manufacturer's quality department (functionally independent from the manufacturing department), based on specific testing of the actual material supplied, with the quality department declaring compliance with the order requirements — the most commonly specified certification level for standard industrial forging supply.
A document validated and countersigned by either a party independent of the manufacturer entirely (a nominated third-party inspection body) or the purchaser's own authorized representative, providing an assurance level beyond the manufacturer's own internal quality function — typically reserved for the most safety-critical or regulated applications.
Guidance on matching certificate type to project risk level and regulatory requirement — most standard industrial forging supply is appropriately served by 3.1 certification, while 3.2 should be reserved for applications where the additional independent validation cost is genuinely justified by application criticality or explicit regulatory/customer requirement.
EN 10204 3.1 certification provided as standard practice for Shivam Forge's forged components, documenting material composition, mechanical test results, and compliance with order specification through our independent quality function.
Coordination of third-party inspection witnessing for 3.2 certification when required, including scheduling with customer-nominated inspection bodies for aerospace, nuclear, or other regulated application requirements.
Guidance helping customers avoid unnecessarily specifying 3.2 certification (and its associated cost and lead time) for applications where 3.1 certification already provides adequate assurance, reserving the additional cost for applications where it delivers genuine risk-reduction value.
Explanation of what information a proper EN 10204 certificate should contain — material grade and heat number, chemical composition results, mechanical test results, heat treatment condition, and traceability to the specific supplied material — regardless of certificate type.
Material certification documentation exists to answer a genuinely important question for any purchaser of forged metal components: how confident can you be that the material actually delivered meets the specification you ordered, and what's the basis for that confidence? EN 10204 provides a standardized European framework for answering this question with graduated levels of assurance, and understanding the distinction between its certificate types is essential to specifying the appropriate level for your project — neither under-specifying (accepting less assurance than your application's risk profile genuinely warrants) nor over-specifying (paying for validation rigor beyond what your application actually needs).
The critical distinction across EN 10204's certificate types is independence of validation, not merely the content of what's tested. A Type 2.2 test report represents the lowest assurance level: results are reported by the manufacturer, potentially based on testing representative of the production method rather than the specific batch supplied, without any independent quality function validation. Type 3.1 represents a meaningful step up: testing is performed specifically on the actual material supplied, and results are validated and declared by the manufacturer's quality department — a function organizationally independent from the manufacturing department itself, even though both remain within the same company. This internal independence matters because it means the party attesting to compliance isn't the same party with direct production incentive to declare the material acceptable.
Type 3.2 certification extends independence a further, meaningful step beyond 3.1 by involving validation from a party entirely independent of the manufacturer — either a third-party inspection body nominated by the customer, or the customer's own authorized representative — witnessing the testing process or independently validating results. This represents genuinely the highest assurance level EN 10204 provides, and its additional cost and scheduling complexity (coordinating third-party witness availability, typically) is why 3.2 is generally reserved for applications where the consequence of an undetected material non-conformance is severe enough to justify that additional assurance investment — aerospace, nuclear, and similarly safety-critical or heavily regulated applications being the classic examples.
For customers seeking guidance on appropriate EN 10204 certification level for their specific forged component project, Shivam Forge provides 3.1 certification as standard practice and coordinates 3.2 third-party witnessing when required. Contact our engineering team at +91-9265772827 or sales@shivamforge.com with your application and any customer or regulatory certification requirement to discuss the right documentation approach.
Both document specific testing of the actual material supplied. The difference is who validates the results: 3.1 is validated by the manufacturer's own quality department (independent from the manufacturing function internally, but still within the manufacturer's organization), while 3.2 adds validation and countersignature by a party independent of the manufacturer entirely — a third-party inspector or the purchaser's own representative — providing a meaningfully higher independent assurance level.
This depends on your application's criticality and any explicit regulatory or customer requirement. Most standard industrial forging applications are well served by 3.1 certification. 3.2 is typically reserved for the most safety-critical or heavily regulated applications (aerospace, nuclear, and similar) where the additional independent validation cost is specifically justified.
A 2.2 test report is issued by the manufacturer based on non-specific testing, without independent validation from a separate quality function — it's a lower assurance level than 3.1 and is generally not adequate for critical or regulated applications, though it may be acceptable for genuinely non-critical general-purpose material supply.
EN 10204 3.1 certification is provided as standard practice for our forged components, documenting material composition, mechanical test results, and order specification compliance through our independent quality function, without requiring a separate certification request.
We coordinate scheduling with your nominated third-party inspection body (or your own authorized representative) to witness testing and validate results as required for 3.2 certification — contact our team early in project planning to allow adequate scheduling lead time for this coordination.
