En 10204
When purchasing steel products, metal manufacturers should release the MTC (Mill Test Certificate) to the buyer. The MTC contains all specifications of steel products including weight, dimensions, chemical composition, mechanical strength, heat treatment status, test results, traceability, etc. This information is to ensure that a certain standard of quality for steel products has been met.
This document supersedes EN. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directives 97/23/EC. For relationship with EU Directive 97/23/EC, see informative Annex ZA, which is an integral part of this document. En 10204是歐盟標準,涉及鋼鐵金屬產品的不同類型的檢驗文件。 EN 102024,2.1,2.2,3.1和3.2有4種類型,後兩種類型主要用於鋼管和板材產品,因此這裏我們將主要介紹兩種類型之間的主要差異。.


In Germany, inspection documents and certifications were originally specified in the DIN 50049 standard. The definitions of material testing and certificate types in DIN 50049 was eventually adopted for the European standard EN 10204, first published in 1991. 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.
EN 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). These now only include types 2.1, 2.2, 3.1 and 3.2. Type 2.3 has been deleted, Type 3.1 replaces 3.1B, and Type 3.2 replaces 3.1A, 3.1C and 3.2. A brief overview of each of the BS EN 10204 certificate types is shown below:
En 10204 3.1 Standard
Certificate Type | Title | Summary of EN 10204 Requirements |
2.1 | Declaration of Compliance with the Order | Statement of compliance with the order by the manufacturer. |
2.1 | Test Report | Statement of compliance with the order by the manufacturer based on non-specific inspections (tests) by the manufacturer. |
3.1 | Inspection Certificate | Statement of compliance with the order by the manufacturer with results of specific inspection |
3.2 | Inspection Certificate | Statement of compliance with the order with indication of results of specific inspection |
The standard is usually applied to metal produced by mills in the form of metal bars, plates, tube, etc. The standard can also be adapted to products manufacturers from such material such as valve bodies, flow meter casings, pressure gauges, etc. Of the 4 types for EN 10204, the latter two types are the most widely used in steel products.
Differences between 3.1 and 3.2
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”). 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 3.2 Inspection Certificate is similar to the 3.1, but has additionally been countersigned and verified by an independent third-party to validate the material by way of verification test. When the 3.2 certificate type is requested the manufacturing mill may prepare a 3.1 type certificate to present to the ‘outside inspector’ to use as a basis for preparing the independent 3.2 certificate.

With a wide offering of sanitary process components, Holland Applied Technologies is familiar with the requirements of a Type 3.1 inspection certificate and we understand its importance to our customers. While the 3.2 certificate is rare due to the higher cost, it provides independent assurance of a material’s properties. If you need more help understanding your 3.1 certificate, or simply need help retrieving a certification for a component you’ve purchased previously, contact a Holland Sales Engineer today.

BS EN 10204:2004 Metallic Products: Types of Inspection Documents
Note: To print, please click here.
Quite often our distributors are asked by end-users for a copy of inspection documents according EN 10204 (especially for the inspection Certificate 3.1 “type 3.1”). In this little bulletin we want to explain what those documents are.
BS EN 10204:2004 is a British Standard that supersedes standard BS EN 10204:1991 and specifies the different types of inspection documents supplied to the purchaser, in accordance with the requirements of the order, for the delivery of all metallic products e.g. plates, sheets, bars, tubes, forgings, castings, whatever their method of production.
EN 10204 And The Quest For Traceability - Hose And Coupling World
Inspection certificate 3.1 “type 3.1” – is simply a document issued by the manufacturer in which he declares that the products supplied are in compliance with the requirements of the order and in which he supplies test results. The test unit and the tests to be carried out are defined by the product specification, the official regulation and corresponding rules and/or the order. The document is validated by the manufacturer`s authorized inspection representative, independent of the manufacturing department.
En 10204 Type 3.2
Manufacturer may transfer on to the inspection certificate 3.1 relevant test results obtained by specific inspection on primary or incoming products he uses (such as – for example – results of chemical composition analysis or mechanical properties of the strip, provided on the Material Test Reports supplied by the vendor of strip)
