BSEN 10204 test certificates for stainless steel productsIntroduction

In Germany inspection documents (certificate types) were originally specified in standard DIN 50049. The definitions ofmaterial 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, 3.1A, 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 BSEN 10204 in October 2004 with a simplified range of inspectiondocuments (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 o f op tions 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 becovered separately eg BSEN 10088-2, for stainless steel sheet or plate type products

Test certi ficate standards and types

Each of the certificate types has a reference number, which has both its content and 'validation' requirements described in thestandard in Appendix A, Table A.1. These descriptions are sometimes a little difficult to interpret and need some additionalinterpretation. The table below shows the full range of current (C) and withdrawn (W) EN 10204 certificate types, with someinterpretation of what they cover. In any case of dispute however the descriptions given in Table A.1 of EN 10204:2004 shouldbe used.

requirementsNotes

2.1Declaration ofcompliance withthe order

CStatement of compliance with theorder by the manufacturer.

No test results shown.

2.2 Test report C

Statement of compliance with theorder by the manufacturer basedon non-specific inspections (tests)by the manufacturer.

Like the old BS1449 'Cast Test' certificate. Mechanical test sample results fromanother coil from same cast, manufactured by the same process route, can beused.

2.3Specific testreport

WWith mention of test results fromspecific inspection and testing

Batch test results needed on the certificate. Difficult to distinguish this from the3.1B type.

3.1 Inspectioncertificate

C Statement of compliance with theorder by the manufacturer withresults 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 independentof the manufacturing department. Eg Inspection department or test housemanager/supervisor.

3.1AInspectioncertificate 3.1A

WWith mention of test results fromspecific inspection and testing

Batch test results. Cert. issued by independent inspector required by releasingauthority (eg TUV for German pressure vessels). Replaced by 3.2 in 2004

3.1BInspectioncertificate 3.1B

WWith mention of test results fromspecific inspection and testing

Batch test results. Cert. issued and signed by manufacturer's representative.Replaced by 3.1 in 2004

3.1CInspectioncertificate 3.1C

WWith mention of test results fromspecific inspection and testing

Batch test results. Cert. issued by independent inspector appointed by customer(eg Lloyds). Replaced by 3.2 in 2004

3.2Inspectioncertificate

CStatement of compliance withorder with indication of results ofspecific inspection

Batch test results. Cert. issued by both manufacturer's representative and anindependent inspector appointed either by the customer (cf withdrawn 3.1C) oran inspector designated by official regulations (cf withdrawn 3.1A). ie 3.2 nowcovers scope of both 3.1A and 3.1C of 1991 edition. This cover what is oftenreferred 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 'outsideinspector' to use as a basis for preparing the independent 3.2 certificate. Only the 3.2 certificate is valid however for theordered requirements and to match the product marking and inspectors stamp.
