Railway applications - Electric equipment for rolling stock - Part 1: General service conditions and general rules
|Publication Date:||1 November 2017|
|ICS Code (Railway rolling stock in general):||45.060.01|
This part of IEC 60077 specifies the general service conditions and requirements for all electric equipment installed in power circuits, auxiliary circuits, control and indicating circuits etc., on railway rolling stock.
NOTE Some of these rules can, after agreement between the user and the manufacturer, be used for electrical equipment installed on vehicles other than railway rolling stock, such as mine locomotives, trolley buses, etc.
The purpose of this document is to harmonize as far as practicable all rules and requirements of a general nature applicable to electric equipment for rolling stock. This is in order to obtain uniformity of requirements and tests throughout the corresponding range of equipment to avoid the need for testing to different standards.
All requirements relating to:
• the environmental stresses expected during the normal service conditions;
• the construction;
• the performance and the associated tests which can be considered as general;
have therefore been gathered in this document together with specific subjects of wide interest and application, for example temperature rise, dielectric properties, etc.
In the event of there being a difference in requirements between this document and a railway rolling stock relevant product standard, then the product standard requirements take precedence.
