En 10204 |verified| -

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.

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. 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.

It is crucial to understand that EN 10204 does not mandate which document type to use. That decision lies with the product standard (e.g., EN 10025 for structural steel) or the customer’s specification. However, the standard provides the format and content rules once a type is chosen. 1. Type 2.1 – Declaration of Compliance with the Order Formal Name: Declaration of compliance with the order Issued by: Manufacturer Third-party verification: None The test results are representative but not traceable

EN 10204, officially titled "Metallic products — Types of inspection documents," is a European standard that defines the different types of inspection documents supplied to the purchaser. It does not specify material properties, tolerances, or testing methods. Instead, it answers a critical question:

"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) Crucially, the testing must be witnessed or evaluated

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.
