International Standards and Conformity Assessment for all electrical, electronic and related technologies



Reference EN 50125-1:2014
Title Railway applications - Environmental conditions for equipment - Part 1: Rolling stock and on-board equipment
Project Number 21987
Abstract/Scope 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 prEN 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).

Normative reference (6)  

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved

(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat

(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level

(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement

(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn

(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.
