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.
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. en 10204

Crucially, the testing must be witnessed or evaluated by a (e.g., a quality control lab that reports to a different management chain). This ensures internal independence.
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.
