Type 2.2 is a step up. The manufacturer provides a document stating that the products comply with the order, and additionally supplies test results. However, these test results come from non-specific inspections – meaning they are based on the manufacturer’s own internal testing regime, not necessarily on tests performed on the specific delivered lot. The tests could be from previous similar production, from internal quality assurance batches, or from type tests.

Introduction In the world of industrial manufacturing, construction, and engineering, trust is a commodity as valuable as the materials themselves. When a steel beam is used in a skyscraper, a pipe in a chemical plant, or a forging in an aircraft landing gear, the buyer needs absolute assurance that the material meets specified requirements. This is where EN 10204 comes into play.

The test results are representative but not traceable to the exact delivery. en 10204

"We hereby declare that the supplied steel bars conform to the requirements of order PO-12345." 2. Type 2.2 – Test Report Formal Name: Test report Issued by: Manufacturer Third-party verification: None (but based on non-specific inspections)

"Test results from routine production monitoring show typical yield strength of 355 MPa. The supplied products comply with EN 10025." 3. Type 3.1 – Inspection Certificate Formal Name: Inspection certificate 3.1 Issued by: Manufacturer (but by an independent inspection department within the manufacturer) Third-party verification: None externally, but internally independent Type 2

For engineers, procurement specialists, and quality managers, understanding EN 10204 is not optional – it is essential to avoid costly liability, ensure regulatory compliance, and build products that are truly fit for purpose. The next time you see “EN 10204 Type 3.1” on a purchase order, you will know exactly what level of trust and traceability is being demanded. Disclaimer: This write-up is for informational purposes. Always consult the official EN 10204:2004 standard and relevant product specifications for legal and contractual compliance.

The standard outlines four main types of inspection documents, designated by numbers: . The higher the number, the greater the level of verification and third-party involvement. The tests could be from previous similar production,

First published in 1991 and significantly revised in 2004 (the current version is EN 10204:2004), this standard has become the de facto global language for material certification, referenced in countless international specifications, from ISO standards to ASTM, and is mandatory for products placed on the European market under the Pressure Equipment Directive (PED) or Construction Products Regulation (CPR). EN 10204 is built on a hierarchy of responsibility and rigor. At its heart, it distinguishes between statements made by the manufacturer (the producer of the metallic product) and those verified by an independent body not associated with the manufacturer.
