INTERPRETATION


MOSTLY  MATERIAL CERTIFICATES ARE PREPARED ACCORDING TO THE CODE  EN 10204

ACCORDING TO THE CODE  THE CERTIFICATES ARE CLASSIFIED IN TO

EN 10204 3.1 Certification  ( inspected only by shop quality control independent of manufacturing)

3.1 is a certificate issued by the mill which declares that the Material are
in compliance with the specification and includes the test results.
Test results are validated by the mill’s in–house test department
which has to be independent of the manufacturing department.

EN 10204 3.2 Certification ( by third party inspectors or both ) (independent of manufacturing)

3.2 Certification is more rigorous and the certificate is prepared jointly by the mill’s inspection department and an independent 3rd party inspectors like TUV or Lloyds Register. The certificate states that the Material are compliant with the relevant specification and the mill test certificate is included.

EN 10204 2.1 and 2.2 Certification

For Type 2 certificates the manufacturer declares compliance but does not specifically inspect the product. 2.1 certificates do not include test results and 2.2 certificates supplies test results based on sampling, or other methodology, and the Material tested will not necessarily be the Material supplied
