DESIGNATED BODY (Debo)
What is a debo mission ?
In addition to International and European Regulations such as the Interoperability Directive, each member state has its own technical and safety rules taking into account their national particularities.
Theses National Notified Technical Rules (NNTR) are defined by the National Safety Authority (NSA), which is also the authority in charge of issuing all the authorisations to put on the market (APOM).
In the framework of this APOM process for new and substantially modified railway systems and subsystems, the NSA usually rely on a Designated Body (DeBo), which is an independent assessment body acknowledged for its competences. The DeBo assesses and verifies the compliance of all phases (design, manufacturing, operation and maintenance) in accordance with national rules in force.
In order to prove the fulfilment of the national rules, the applicant, which can be an operator, an infrastructure manager or a manufacturer, has to submit to the NSA the report and/or certificate provided by the Designated Body in charge of the assessment of the project according to the national rules.
DeBo deliveries are key documents for the applicant to obtain a marketing authorization.
what is the role of the debo ?
The DeBo carries out an assessment mission which may concern an entire railway system or subsystem according to the Notified National Technical Rules (NNTR), from the design phase to the final tests.
The DeBo issues its recommendation about the conformity of the assessed system with NNTR on the basis of documentary reviews, audits and site visits when deemed relevant.
When the assessment and test results reveal compliance with the national rules, the DeBo delivers a final DeBo report based on the NNTR and a Certificate.
The assessment of the Designated body can be done from the design phase to final tests, but the final Designated Body report and the Certificate of verification in accordance to national rules are issued at the end of the project i.e. after the completion of Design, Construction, Installation and Testing phases.
