Standards description

Shock and vibration tests IEC/EN 61373 category 1 class B
This international standard specifies the requirements for
testing items of equipment intended for use on railway vehicles
which are subsequently subjected to vibrations and shock
owing to the nature of railway operational environment.
To gain assurance that the quality of the equipment is
acceptable, it has to withstand tests of reasonable duration
that simulate the service conditions seen throughout its
expected life.

Note: the figure identifies general location of equipment on railway vehicles.
Equipment’s location within the vehicle: category 1 (body mounted), category 2 (bogie
mounted C) and category 3 (axle mounted) divided into 2 subgroups, according to the
location of the components:
– class A: cubicles, subassemblies, equipment and components mounted directly on
or under the car body.
– class B: anything mounted inside an equipment case which is in turn mounted
directly on or under the car body

Category Class Location Description of equipment location
Category 1 Class A M N O I and J Components mounted directly on to or under the car body
Class B D Components mounted into an underframe internal cubicle which is in turn fixed to the car body
K and E Components mounted into a large internal cubicle which is in turn fixed to the car body
F Components mounted into subassemblies which are mounted into a cubicle which is in turn fixed
to the car body
Category 2 G Cubicles, subassemblies, equipment and components, which are mounted on to the bogie of a railway vehicle
Category 3 H Subassemblies, equipment and components or assemblies, which are mounted on to the axle assembly
of a railway vehicle
