EN 15663:2009

The purpose of this document is to define a set of reference masses that can be used as a common startingpoint for specifying the requirements for the design, testing, delivery acceptance, marking and operation of railvehicles. It is not the intention of this European Standard to change the dimensioning of vehicle systemcomponents by the definition of these common reference masses. However, when the relevant standards arerevised or new ones developed, the masses to be used in these vehicle system component standards as thebasis for the design should be expressed as a function of the reference mass states defined in this standard.Until the standards are changed the existing criteria continue to apply.This document covers all types of rail vehicles.For the purpose of vehicle mass definitions rolling stock is divided into three vehicle groups which are: high speed and other long distance trains; passenger vehicles other than high speed and long distance trains, including metro and tramway; freight vehicles (wagons and freight motored units).Locomotives are treated as passenger vehicles without payload.The specification of the technical requirements of the railway vehicle should contain the information to whichvehicle group it belongs.NOTE “Long distance” includes all passenger trains not intended to be used on commuter and suburban services. Inthis standard, commuter is understood as: for the French network: RER; for the German network: S-Bahn.The masses defined in this European Standard are as follows (see Clause 2):a) dead mass;b) design mass;1) design mass, in working order;2) design mass under normal payload;3) design mass under exceptional payload;c) operational mass;1) operational mass, in working order;2) operational mass under normal payload.These masses are defined with respect to the whole vehicle, but they can also apply to a specific system orcomponent.
