This European Standard specifies the requirements for the digital automatic coupler (DAC) for freight compliant with the Technical Specification relating to the subsystem ‘rolling stock — freight wagons’ of the rail system in the European Union Commission Regulation (EU) No 321/2013 of 13 March 2013 and repealing Decision 2006/861/EC and EU regulation 2019/776. Commission Regulation (EU) No 1302/2014 of 18 November 2014 concerning a technical specification for interoperability relating to the ‘rolling stock — locomotives and passenger rolling stock’. This standard specifies the minimum interface requirements to allow automatic coupling (mechanical and pneumatic) of two digital automatic couplers. The standard further specifies the mechanical interfaces needed for the interoperability of electrical couplers. It does not cover the electrical contacts needed. The standard covers the requirements for DACs integrated into locomotives. Coupler-to-coupler interfaces for the Hybrid coupler solutions will be covered in this standard. All non-mechanical interfaces such as the digital and electrical requirements needed for the DAC are defined in the scope of CENELEC/TC9X/WG 15-10.
