This document establishes requirements, test procedures, assessment methods and acceptance criteria for aerodynamics in tunnels and rolling stock in tunnels. Topics of aerodynamic pressures and loadings, aerodynamic resistance and micro-pressure waves are addressed.

Requirements for rolling stock with operating speeds equal to or above 200 km/h are provided for pressures generated in tunnel operation. Requirements for infrastructure with design speeds above 160 km/h or high blockage ratio or tunnels longer than 12 km are provided for pressures generated in tunnel operation. These requirements are not applicable to light rail and urban rail.

This document is applicable to all railway vehicles and infrastructure with track gauges from 1 435 mm to 1 668 mm inclusive.

This document is applicable to testing of rails installed in track for detecting rail surface cracks. This part of this European Standard applies to testing equipment in inspection-trains or reprofiling machines and manual systems. This document specifies the requirement for testing principles and systems in order to produce comparable results in respect to the location and the characteristic of surface cracks. This document is not aiming to give any guidelines for managing the result of eddy current rail testing. This document does not define the requirements for vehicle acceptance. This document is not concerned with production testing of rails in a production plant. This document applies only to rail profiles meeting the requirements of EN 13674-1.

This document specifies the minimum requirements for track geometry measuring principles and systems in order to produce comparable results when measuring the same track. It applies to all measuring systems, attended or unattended, fitted on any vehicle, except those systems defined in EN 13848-3 and EN 13848-4. Only systems put into service after the standard comes into force are concerned.

This document doesn't define the requirements for vehicle acceptance.

This document does not apply to measuring systems dedicated to Urban Rail Systems.
