Introduction
To define the design, testing and operation of vehicles in general and their main constituent parts, it is
necessary to clearly specify the associated states of loading. This European Standard provides such a set
of vehicle reference masses and describes how each is derived.
1 Scope
This European Standard defines a set of reference masses for specifying the requirements for the
design, testing, acceptance, marking, delivery and operation of rail vehicles.
The reference masses defined in this document are as follows:
— dead mass;
— design mass in working order;
— design mass under normal payload;
— design mass under exceptional payload;
— operational mass in working order;
— operational mass under normal payload.
These reference masses are defined with respect to the whole vehicle, but they can also apply to a
specific system or component.
The specification of values for tolerances applicable to reference masses is not in the scope of this
standard. Tolerances can be required by an application standard.
Additional loadings due to environmental factors, for example snow and retained or absorbed
rainwater, are not in the scope of this European Standard.

3.1 Terms and definitions
#For the purposes of this document, the terms and definition defined in EN 17343:2023 and the
following apply.$
!ISO and IEC maintain terminological databases for use in standardization at the following addresses:

• ISO Online browsing platform: available at http://www.iso.org/obp"
3.1.1
mass increment
quantity added to or subtracted from the vehicle mass
Note 1 to entry: Examples are payload, staff, consumables and wear allowances.
3.1.2
payload
mass increment for the load carried by the vehicle (passengers, luggage or cargo)
Note 1 to entry: Typically a load from which revenue is derived.
3.1.3
luggage compartment
closed area, for the carriage of luggage and goods, which is not intended for the transport of passengers
3.1.4
luggage area
low level location or unit in a passenger saloon or vestibule provided to store luggage
Note 1 to entry: Overhead luggage racks are not regarded as luggage areas.
3.1.5
passenger area
area inside the vehicle dedicated for transporting passengers
Note 1 to entry: Catering areas are not regarded as passenger areas.
3.1.6
catering area
area set aside for passengers for the purchase or consumption of catering services (e.g. buffet, bar or
bistro)
3.1.7
standing area
unobstructed part of either a passenger area or a catering area which can be used by standing
passengers (e.g. vestibules, aisles, stairways)
3.1.8
normal seat
permanent seat in a passenger or catering area
3.1.9
tip up seat
folding seat fixed to a wall or partition for temporary use
3.1.10
wear allowance
quantity of mass that is assumed to be lost in service due to abrasion and mechanical wear
Note 1 to entry: The main sources of wear to be accounted for are from wheels and brake friction materials.
#
3.1.11
dead mass
mass of the vehicle in the 'as built' condition without consumables and without staff
Note 1 to entry: 4.3 gives a detailed definition.
3.1.12
working order
condition in which the vehicle is available for service, including staff and an amount of consumables, but
without any payload
Note 1 to entry The amount of consumables depends on the vehicle condition (design condition or operational
condition) as given in Table 6.
Note 2 to entry This state is sometimes described as unladen or tare. Nevertheless, the use of the expression
“working order” is encouraged to harmonize wording.
3.1.13
normal payload
typical payload seen on a regular basis
Note 1 to entry The normal payload depends on the vehicle condition (design or operational condition) as
given in Table 4.
Note 2 to entry 4.4 gives a detailed definition.
Note 3 to entry For freight vehicles, the payload is always taken as the maximum payload as specified in the
loading table of the vehicle.
3.1.14
exceptional payload
maximum possible payload that can be carried and that will be experienced only under exceptional
conditions
Note 1 to entry: The exceptional payload is only defined for the design condition.
Note 2 to entry: 4.4 gives a detailed definition.,
3.1.15
design condition
theoretical state for analysis and calculation
3.1.16
operational condition
assumed average state when in service
3.1.17
special purpose mass
mass, specified in an application standard based on the reference mass definitions in accordance with
this document
Note 1 to entry: In accordance with this definition, a reference mass used directly by an application standard is
not considered as a special purpose mass.
Note 2 to entry: 4.6 gives detailed information about the application mass definitions.$

C Consumables, staff and wear allowance
V in working order (Vide)
N Normal
X eXceptional
The third letter denotes the condition that is required (see 4.1):
D Design condition
O Operational condition
