Introduction
To achieve an undisturbed, reliable and safe operation of heavy rail freight wagons it is essential to
specify common requirements for closing and locking devices for payload protecting devices of
interoperable freight wagons with respect to e.g. structural requirements, operating characteristics, way
of operation, maintenance as well as their handling.
1 Scope
This document specifies the requirements for closing and locking devices of heavy rail freight wagons
including durability, their status indication, maintenance and recycling.
Annex A specifies pass-fail criteria for the dimensioning tests.
This document is not applicable to closing and locking devices which are used to ensure a pressure
difference or to retain liquids/liquid payloads.
This document is not applicable to heavy rail freight wagons which are emptied by pressure, nor is it
applicable to lose tarpaulins.

constitutes requirements of this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments) applies.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in EN 17343:2023 and the following
apply.
ISO and IEC maintain terminology databases for use in standardization at the following addresses:
— ISO Online browsing platform: available at https://www.iso.org/obp/
— IEC Electropedia: available at https://www.electropedia.org/
3.1
aerodynamic force
force affecting the rail vehicle and component assemblies by an air stream
3.2
movable protecting device
device to protect payload against environmental influences and exterior forces
Note 1 to entry: Loose tarpaulins are not considered as a movable protecting device.
EXAMPLES Sliding walls, flaps, rigid sliding hoods and covers, hinged doors, bottom doors.
3.3
closing and locking device
device for fixing a movable protecting device in a defined position
3.4
types of devices for closing and locking
3.4.1
door for discharge
unloading door of gravity discharge freight wagons and their closing and locking devices
Note 1 to entry: The door should be able to be secured against un-planned opening (category 2).
3.4.2
sliding wall
movable side wall with an opening length of ~50 % loading length of covered freight wagons for
particular freight and their closing and locking devices
3.4.3
side door
hinged door at the side of covered freight wagons for particular freight or cars or for high-sided open
freight wagons for scrap or bulk transport and their closing and locking devices
3.4.4
curtain side
movable curtain (instead of side walls) of covered freight wagons for particular freight and their closing
and locking devices
3.4.5
tarpaulin cover
movable tarpaulin roof with an opening length of ~2/3 loading length of flat freight wagons with end
walls for weather sensitive bulky goods or tarpaulin sliding cover of high-sided open freight wagons for
weather sensitive payload and their closing and locking devices
3.5
operating element
element which is operated during loading/unloading
EXAMPLES Removable stanchions, hand wheels, sliding walls, levers or movable tie-downs.
3.6
percentile
statement on how many participants of the test group (in percent) are able to summon up the applied
force or applied moment
Note 1 to entry: The applied forces or moments stated in the standards always refer to certain percentiles of the
test group.
Note 2 to entry: Typical values of percentiles are 1, 5, 15, 50 or 95. Here the difference between 100 and the
percentile value describes the percentage of the test group, which is able to summon up more than the respective
applied force or moment. When stating the 85th percentile this means for instance that 85 % of the test persons are
able to carry out the described activity – and 15 % will be able to carry out more than the described activity. When
stating the 15th percentile this means for instance that 15 % of the test persons are not able to carry out the
described activity – and 85 % will be able to carry out the described activity.
3.7
types of load
classification in two types of loads which are considered for the design of closing and locking devices
Note 1 to entry: These loads are either internal forces from the load itself or external forces during travelling.
Note 2 to entry: Examples for when these loads are considered for different door types are shown in Table 1.
3.8
automatic safety device
automatic device that prevents danger from wrong operation to and by the user
3.9
safeguard device
device that safely locks
