A 3.1 Inspection Certificate is endorsed only by the manufacturers own representative who has to be independent from the manufacturing process, such as the Quality department or a test house manager/supervisor. The EN 10204 Type 3.1 Inspection Certificate are actual test results from the material in the lot from which the steel products have been supplied (formally referred to as “specific testing”).

Of the 4 types for EN 10204, the latter two types are the most widely used in steel products. The standard can also be adapted to products manufacturers from such material such as valve bodies, flow meter casings, pressure gauges, etc. The standard is usually applied to metal produced by mills in the form of metal bars, plates, tube, etc.

Statement of compliance with the order with indication of results of specific inspection Statement of compliance with the order by the manufacturer with results of specific inspection Statement of compliance with the order by the manufacturer based on non-specific inspections (tests) by the manufacturer. Statement of compliance with the order by the manufacturer. A brief overview of each of the BS EN 10204 certificate types is shown below: Type 2.3 has been deleted, Type 3.1 replaces 3.1B, and Type 3.2 replaces 3.1A, 3.1C and 3.2. These now only include types 2.1, 2.2, 3.1 and 3.2. Certificate types 2.1, 2.2, 2.3, 3.1A, 3.1B, 3.1C, and 3.2 were defined, closely following the definitions in the German standard.ĮN 10204 was revised in 2004 and published as BS EN 10204:2004, Metallic Products-Types of Inspection Documents, with a simplified range of inspection documents (certificate types). The definitions of material testing and certificate types in DIN 50049 was eventually adopted for the European standard EN 10204, first published in 1991. In Germany, inspection documents and certifications were originally specified in the DIN 50049 standard. This information is to ensure that a certain standard of quality for steel products has been met.

The MTC contains all specifications of steel products including weight, dimensions, chemical composition, mechanical strength, heat treatment status, test results, traceability, etc. When purchasing steel products, metal manufacturers should release the MTC (Mill Test Certificate) to the buyer.
