Requirement of different EN certification for welding consumable is shown below:
|
Certificate Type |
Title | Summary of EN10204 requirements |
Notes |
|
2.1 |
Declaration of compliance with the order | Statement of compliance with the order by the manufacturer | No test results shown |
|
2.2 |
Test report | 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. |
|
3.1 |
Inspection certificate | Statement of compliance with the order by the manufacturer with results of specific inspection | 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 |
|
3.2 |
Inspection certificate | 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 or an inspector designated by official regulations. 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.
