: Meets safety regulations like the Pressure Equipment Directive (PED) . The Four Types of Certificates
The difference is not in the data but in the independence of verification . A 3.2 certificate means no one from the manufacturer’s payroll has the final say – an external expert has approved the results.
The benefits of EN 10204 include:
This is the most commonly specified document in heavy industry. Type 3.1 requires that the manufacturer provide a certificate confirming compliance with the order, and that the test results come from specific inspection – meaning tests performed on the actual products or the specific casting/heat/lot to be delivered.
: Ensuring stainless steel (like AISI 316L) has the correct molybdenum content to resist acids. en 10204
: A statement of compliance that includes results from non-specific tests. This means the manufacturer tested similar products from the same production process to verify quality. Specific Inspection (Type 3.1 and 3.2)
The manufacturer carries out inspections according to their own procedures, but the tests are not necessarily performed on the exact products delivered to you. : Meets safety regulations like the Pressure Equipment
EN 10204 is a European standard that defines the different types of inspection documents for metallic products. It ensures that materials like steel, aluminum, and copper meet specific requirements before they are used in critical infrastructure or manufacturing. What is EN 10204?
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). The benefits of EN 10204 include: This is
