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.
En 10204 Types
En 10204 3.1 Inspection Certificate
In Germany inspection documents (certificate types) were originally specified in standard DIN 50049. The definitions of material testing and certificate types in DIN 50049 was adopted for European standard EN 10204, first published in 1991.
Certificate types 2.1, 2.2, 2.3, 3.1 and 3.2 were defined, closely following the definitions in the German standard. EN 10204 was revised in 2004 and published as EN 10204 in 2004 with a simplified range of inspection document (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
Type 3.2 replaces 3.1A, 3.1C and 3.2 of the previous edition.
This reduced range of options should be easier to understand and work with.
When this standard and certificate type is shown, it only refers to the certificate type and not the steel standard. This should be covered separately eg EN 10088-2, for stainless steel sheet or plate type products
Each of the certificate types has a reference number, which has both its content and 'validation' requirements described in the standard in Appendix A, Table A.1. These descriptions are sometimes a little difficult to interpret and need some additional interpretation. The table below show the range of current (C) and withdrawn (W) EN 10204 certificate, with some interpretation of what they cover. In any case of dispute however the descriptions given in Table A.1 of EN 10204:2004 should be used.
European standard EN 10204 defines different types of certificates (inspection documents), which are provided to the customer (to the consumer) according to the requirements of the contract, upon delivery of all metal products, eg, slabs, sheets, rods, forgings, castings for any method of their manufacture. EN 10204 TYPE 3.2 CERTIFICATION Type 3.2 certification involves visits to the client facility by the third-party surveyor for visual examination, sample dimensional checks, confirmation that materials are traceable back to their ladle chemical analysis and validation that their properties meet material specification requirements.

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。.
| Certificate type | Title | Status | Summary of EN10204 requirements | Notes |
| 2.1 | Declaration of compliance with the order | C | Statement of compliance with the order by the manufacturer. | No test results shown. |
| 2.2 | Test report | C | Statement of compliance with the order by the manufacturer based on non-specific inspections (tests) by the manufacturer. | Like the old BS1449 'Cast Test' certificate. Mechanical test sample results from another coil from same cast, manufactured by the same process route, can be used. |
| 2.3 | Specific test report | W | With mention of test results from specific inspection and testing | Batch test results needed on the certificate. Difficult to distinguish this from the 3.1B type. |
| 3.1 | Inspection certificate | C | Statement of compliance with the order by the manufacturer with results of specific inspection | Replaces 3.1B. Common certificate type issued for 'batch tested' material. Cert. issued and signed by manufacturer's representative, who must be independent of the manufacturing department. Eg Inspection department or test house manager/supervisor. |
| 3.1A | Inspection certificate 3.1A | W | With mention of test results from specific inspection and testing | Batch test results. Cert. issued by independent inspector required by releasing authority (eg TUV for German pressure vessels). Replaced by 3.2 in 2004 |
| 3.1B | Inspection certificate 3.1B | W | With mention of test results from specific inspection and testing | Batch test results. Cert. issued and signed by manufacturer's representative. Replaced by 3.1 in 2004 |
| 3.1C | Inspection certificate 3.1C | W | With mention of test results from specific inspection and testing | Batch test results. Cert. issued by independent inspector appointed by customer (eg Lloyds). Replaced by 3.2 in 2004 |
| 3.2 | Inspection certificate | C | Statement of compliance with order with indication of results of specific inspection | Batch test results. Cert. issued by both manufacturer's representative and an independent inspector appointed either by the customer (cf withdrawn 3.1C) or an inspector designated by official regulations (cf withdrawn 3.1A). ie 3.2 now covers scope of both 3.1A and 3.1C of 1991 edition. This cover what is often referred to as 'outside inspection' |
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. Only the 3.2 certificate is valid however for the ordered requirements and to match the product marking and inspectors stamp.
