Notified, Designated and Approved Body

As part of a drive to harmonise standards across Europe's rail networks, the EU published legislation – in particular the landmark Railway Interoperability Directive 2008/57/EC  and Directive 2016/797 – aimed at standardising relevant interoperable elements of rolling stock and rail infrastructure between member states. These detailed requirements are set out in the Technical Specifications for Interoperability (TSIs).

A Notified Body (NoBo) is an organisation with proven impartiality and competence credentials that has been appointed by EU member states and notified to the European Commission to perform verification activities against relevant Directives.

In the rail sector, a NoBo must be appointed to carry out verification tasks during any major construction, upgrades or renewals of railway systems before permission can be sought to enter into service.  A NoBo will conduct document reviews and site visits, during which it will compile the Technical File for submission to the National Safety Authority or the European Union Agency for Railways and ultimately provide accredited certification.

Ricardo Certification BV and Ricardo Certification Denmark ApS are accredited to ISO/IEC 17065 and provide European rail sector Notified Body (NoBo) services. The accreditations cover all relevant structural and transverse sub-systems and their defined interoperability constituents:

• Infrastructure (including the Persons with Disabilities and with Reduced Mobility and the Safety in Railway Tunnels Technical Specifications for Interoperability)
• Energy
• Control, Command and Signalling
• Rolling stock (including Wagon and Noise)

A Designated Body (DeBo) works in a similar fashion on a project, undertaking conformity assessments with notified national technical rules (NNTRs).

Ricardo Certification companies that are accredited as a Certification Body to ISO/IEC 17065 are also appointed/recognised as a Designated Body (DeBo) and can carry out conformity assessments against national rules in the following countries:

• The United Kingdom, via Ricardo Certification Limited
• The Netherlands, Belgium, and Ireland via Ricardo Certification BV
• Spain, via Ricardo Certification Iberia S.L
• Denmark, via Ricardo Certification Denmark Ap

Elsewhere, the relevant bodies can work with local organisations to provide the necessary services.

Following the UK's departure from the EU in January 2021, much of the legislative landscape remained unchanged, although some terminalogy was changed.

The TSIs were replaced by National Technical Specification Notices (NTSNs), although much of the orginal details were retained. The term 'Notified Body' was replaced with Approved Body (ApBo). In the UK mainline, it is the responsibility of an ApBo to assess the railway sub-systems against the NTSNs.

Ricardo Certification Limited is accredited to provide Approved Body services in the UK.
