This International Standard specifies general criteria to demonstrate by testing that newly constructed complete railway vehicles conform with standards or other normative documents. This International Standard, as a whole or in part, applies to all railway vehicles except special purpose vehicles such as track-laying machines, ballast cleaners and personnel carriers. The extent of application of the standard for particular vehicles will be specifically mentioned in the contract, to take account, where necessary, of any legislative requirements. NOTE 1 The parts of the standard which are applicable will depend on the type of vehicle (e.g. passenger, freight, powered trailer, etc.). NOTE 2 The scope of this standard excludes railbound and road/rail vehicles for construction and maintenance of railway infrastructure. NOTE 3 This standard does not deal with tests carried out on components or equipment before fitting to the vehicle. In so far as this International Standard is applicable, it may be used for the following: generator sets mounted on a vehicle provided for auxiliary purposes; electrical transmission used on trolley buses or similar vehicles; control and auxiliary equipment of vehicles with non-electrical propulsion systems; vehicles guided, supported or electrically propelled by systems which do not use the adhesion between wheel and rail. NOTE 4 Specific technical requirements apply to vehicles which operate on the railways in the European Union. The source of those requirements is given in Annex B. Where a European requirement applies to a given clause, a note has been inserted at the end of the clause.
