DESIGNATED BODY (DEBO)
WHAT IS A DEBO MISSION ?
In addition to International and European Regulation such as the Interoperability Directive, each member state has its own technical and safety rule staking 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 marketing authorizations (APIS).
In the frame work of these APIS 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 competencies. 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 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 conducts an assessment mission which can be done on complete railway system or subsystem in accordance with the national notified technical rules (NNTR) from the design phase to final tests.
The DeBo issues its opinion about the conformity of the assessed system with NNTR on the basis of documentary reviews, audits and sites visits when deemed relevant.
When the assessment and test results reveal compliance to national requirements, the DeBo delivers a final DeBo report based on the NNTR and a Certificate ensuring the compliance with national rules.
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.
