Railway applications - Environmental conditions for equipment - Part 1: Equipment on board rolling stock
EN 50125-1 intends to define environmental conditions within Europe. The scope of this European Standard covers the definitions and ranges of the following parameters: Altitude, temperature, humidity, air movement, rain, snow and hail, ice, solar radiation, lightning, pollution for rolling stock and on-board equipment (mechanical, electromechanical, electrical, electronic). In particular, this European Standard defines interface conditions between the vehicle and its environment. The defined environmental conditions are considered as normal in service. Rolling stock or parts of it can also be used outside the specification with reduced performance. Microclimates surrounding components may be defined by relevant product standards or by special requirements. Passenger effects on the equipment and equipment effects on the passengers are not considered in this European Standard. This European Standard does not apply to cranes, mining vehicles, cable cars. This European Standard also does not apply to natural disaster (e.g. earthquake).

Železniške naprave - Okoljski pogoji za opremo - 1. del: Oprema na voznih sredstvih
Namen standard EN 50125-1 je opredeliti okoljske pogoje v Evropi. Področje uporabe tega evropskega standarda zajema definicije in razpone naslednjih parametrov: Nadmorska višina, temperatura, vlažnost, premikanje zraka, dež, sneg in toča, led, sončno sevanje, onesnaževanje, ki ga povzročajo vozna sredstva in oprema v vozilih (mehanska, elektromehanska, električna, elektronska). Ta evropski standard posebej opredeljuje vmesne pogoje med vozilom in okoljem. Opredeljene okoljske pogoje se obravnava kot normalne. Vozna sredstva ali njihovi deli se lahko uporabljajo zunaj te specifikacije z zmanjšano učinkovitostjo. Mikroklime, v katerih se komponente nahajajo, so lahko opredeljene s standardi ustreznih proizvodov ali s posebnimi zahtevami. Ta evropski standard se ne nanaša na vpliv potnikov na opremo in vpliv opreme na potnike. Ta evropski standard ne velja za dvigala, rudarska vozila in žičnice. Ta evropski standard se tudi ne nanaša na naravne nesreče (npr. potres).

This European Standard intends to define environmental conditions within Europe.
NOTE 1 It can also be applied elsewhere by agreement.
The scope of this European Standard covers the definitions and ranges of the following parameters:
Altitude, temperature, humidity, air movement, rain, snow and hail, ice, solar radiation, lightning,
pollution for rolling stock and on-board equipment (mechanical, electromechanical, electrical,
electronic).
In particular, this European Standard defines interface conditions between the vehicle and its
environment. The defined environmental conditions are considered as normal in service.
NOTE 2 Further guidance on severe conditions can be found within prCEN/TR 16251.
Rolling stock or parts of it can also be used outside the specification with reduced performance.
NOTE 3 In these cases, relevant operating rules could be necessary to ensure the technical compatibility between the rolling
stock and environmental conditions.
Microclimates surrounding components may be defined by relevant product standards or by special
requirements. Passenger effects on the equipment and equipment effects on the passengers are not
considered in this European Standard.
This European Standard does not apply to cranes, mining vehicles, cable cars. This European
Standard also does not apply to natural disaster (e.g. earthquake).

3.1
environmental condition
physical, chemical or biological condition, external to a product to which it is subjected at a certain
time
3.2
vehicle compartment
enclosure for housing of mechanical, electrical and/or electronic equipment
3.3
environmental parameters
one or more physical, chemical or biological properties characterising an environmental factor (e.g.
temperature, humidity)
EXAMPLE The environmental factor “snow and hail” is characterised by the parameters: snow level above top of rail and
diameter of the hailstones.
3.4
severity of environmental parameters
value of each quantity characterising the environmental parameter
EXAMPLE The severity of snow is defined by values of snow level above top of rail (in mm).
4 Environmental conditions
4.1 General
In the following clauses the environmental parameters are given at which the vehicle and its
equipment shall function as specified.
In the text, normal environmental conditions are considered as being those of Europe. They are
classified with a suffix 1, 2, 3, etc. and special conditions with a suffix X.
The class shall be required in the specification, otherwise the class with suffix 1 shall be assumed.
NOTE Except otherwise stated in this document, general information is given by EN 60721-3-5, HD 478.2.1 S1,
HD 478.2.2 S1, HD 478.2.3 S1 and HD 478.2.7 S1.
The severities specified are those which will have a low probability of being exceeded. All specified
values are maximum or limiting values. These values may be reached, but do not occur permanently.
Depending on the situation there may be different frequencies of occurrence related to a certain period
of time. Such frequencies of occurrence have not been included in this European Standard, but should
be considered for any environmental parameter. They should be additionally specified if applicable.
4.2 Altitude
The vehicle and its equipment shall perform as specified for the different classes of altitude range
relative to sea level given in Table 1.
