5. CertiFiCAtiOn
All materials are available with various certificates, from a 2.2 factory certificate to a
3.2 certificate. If a product has not been certified according to your required authority, we
can have this approval carried out for you by qualified bodies. Generally, a 3.1 certificate is
available for all plates, bars and profiles. A 3.2 certificate is available for various plates and
profiles as standard, depending on the required inspection authority. Below is a brief
explanation of the significance of the various inspection documents.
2.2 FACtOry inSPeCtiOn CertiFiCAte
This document normally only shows a chemical analysis of the product and sometimes a few
mechanical values. These results come from random measurements taken during production
in the factory and have relationship to the material that is ultimately delivered. There is no
direct relationship between the supplied product and the inspection document in the form
of stamps, etc. The document is declared valid by the producer (and signed).
3.1 inSPeCtiOn rePOrt
This document shows test results prescribed in the product standard from the party
(batch/production run) that supplies the final material. There is a direct relationship
between the product and the document. The relationship is guaranteed by a stamp/
paint marks/labels or something similar. An independent authorised controller in the
factory signs the inspection document. This is usually somebody who works in
quality management.
3.2 inSPeCtiOn rePOrt
As for a 3.1 certificate, but with the signature of an inspection body (e.g. Lloyds’DNV/ABS)
designated by the purchaser. This can be done directly during production in the factory (3.2),
or afterwards through so-called external approval (3.1 with supplemental inspection 3.2).
The controller of the inspection body is mostly present during sampling and/or testing.
The document is often given a cover page that is signed by the controller and refers to
the 3.1 document prepared and attached by the factory.
