EN 10204 Test Certificates for Stainless SteelIn Germany inspection documents (certificate types) were originally specified in 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 3.1BType 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, for stainless steel sheet or plate type products.
Test certificate standards and typesEach 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 The table below show the range of current (C) and withdrawn (W) EN 10204 certificate, with some interpretation of what they cover.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 should be used.Certificate typeTitleStatusSummary of EN10204 requirementsNotes2.1Declaration of compliance with the orderCStatement of compliance with the order by the manufacturer.No test results shown.2.2Test reportCStatement 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.2.3Specific test reportWWith mention of test results from specific inspection and testingBatch test results needed on the certificate.
Difficult to distinguish this from the 3.1B type.3.1Inspection certificateCStatement of compliance with the order by the manufacturer with results of specific inspectionReplaces 3.1B. Common certificate type issued for 'batch tested' material. Issued and signed by manufacturer's representative, who must be independent of the manufacturing department. Eg Inspection department or test house manager/supervisor.3.1AInspection certificate 3.1AWWith mention of test results from specific inspection and testingBatch test results. Issued by independent inspector required by releasing authority (eg TUV for German pressure vessels). Replaced by 3.2 in 20043.1BInspection certificate 3.1BWWith mention of test results from specific inspection and testingBatch test results. Issued and signed by manufacturer's representative.
Replaced by 3.1 in 20043.1CInspection certificate 3.1CWWith mention of test results from specific inspection and testingBatch test results. Issued by independent inspector appointed by customer (eg Lloyds). Replaced by 3.2 in 20043.2Inspection certificateCStatement of compliance with order with indication of results of specific inspectionBatch test results. 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.

BS EN is British Standard that related to different types of inspection documents for steel metal products. There are 4 types for EN 102024, 2.1, 2.2, 3.1 and 3.2, the later two types are the mostly used in steel pipe and plates products, so here we will mainly introduce the major differences between two types.
What is EN 10204 means?When we purchasing steel products like, or steel plates, manufacturer should release the MTC to the buyer. MTC is Mill Test Certificate, it contains all the specification of the steel pipe products. Including dimensions, sizes, weight, chemical composition, mechanical strength, heat treatment status, test result, traceability etc.
These information is to make sure the quality of ordered steel products, tells the buyer what situations could be applied in engineering purposes. So the certificate standard for the MTC is generated, EN 10204 is European standard for the inspection documents for the steel products including steel line pipe, fittings, steel plate, valves, sucker rods etc.
En 10204 3.1 Standard
For certifying the results of the specific test is complied with client’s order. Differences between EN 10204-3.1 and 3.2 for the MTCEN 10204 contains 4 types of document type, 2.1, 2.2, 3.1 and 3.2. Type 2.1 and 2.2 are validated by the manufacturer. Type 3.1 and 3.2 are not only validated by manufacturer.Type 2.1, The content is statement of compliance with the order. Validated by manufacturer.Type 2.2, Statement of compliance with the order, with indication of results of non specific inspection.
Validated by manufacturer.Type 3.1, Statement of compliance with the order, with indication of results of specific inspection. Authorized inspection representative by the manufacturer, but is independent of the manufacturing department.Type 3.2, Statement of compliance with the order, with indication of results of specific inspection. Authorized inspection representative by the manufacturer, independent of manufacturing department and either the buyer’s authorized inspection representative or the inspector designated by the official regulations.
EN 10204-3.1 type quality certificate.It requires the manufacturer to show the actual test result for the steel pipes on sale. According the related standard sampling methods.3.1 MTC requires the test agency shall be an independent party, mill has no rights to revise the test results.If a steel pipe manufacturer passed the audit for the ISO 9001 from a certification agency of European Union, then this manufacturer have the qualification to release the EN 10204-3.1 MTC. The buyer information shall be specified on the MTC quality certificate, and one buyer need one MTC quality certificate. If the manufacturer didn’t pass ISO 9001 or the ISO 9001 certificate not from European Union Inspection Agency, then the manufacturer do not have right to release MTC of EN 10204-3.1. In this case, manufacturer shall apply for the EN 10204-3.2 quality certificate from the third part of inspection agency.
EN 10204-3.2 type quality certificate.EN 10204 3.2 certificate is the most restrict standard level for the steel pipe products.It indicates the certification shall be additional countersigned and verified by independent related all the tests, 3.2 certificate cost higher than 3.1. Not only manufacturer test department, but also a completely independent part.
Third party inspector, or the personal, buyer, or government’s representative also have right to verify the test results.EN 10204-3.2 certificate must released by the inspection agency that authorized by the European Union. Through the related inspection or the test for the material that ordered, to certify that the test result is the same with the PO from a third party inspection agency. Also on the quality certificate of EN 10204-3.2 shall specify the name of manufacturer and the buyer. EN 10204 certificate related steel pipe MTC in following specs. Chemical composition. Mechanical strength. Impact strength.
Tensile strength. Hardeness test. Bend test. NDE. Visual and Dimensions. Hydro test. NDT test.
Magnetic test. Pipe end. Corrosion HIC status.
Heat no.
