BSEN 10204 test certificates for stainless steel products

Introduction

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, 3.1A, 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 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
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 BSEN 10088-2, for stainless steel sheet or plate type products

Test certificate standards and types

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 The table below shows the full range of current (C) and withdrawn (W) EN 10204 certificate types, with some interpretation of what they cover.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.

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 ind

ependent 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.
