BS EN 60077-1:2017

What is BS EN 60077-1 -  General service conditions and general rules for electric equipment about?  

BS EN 60077 is a European standard that discusses electric equipment for rolling stock in railway applications. BS EN 60077-1 provides general service conditions and general rules for electric equipment for rolling stock to ensure the proper functioning of the equipment. 

BS EN 60077-1 is the first part of a multi-part series that outlines 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. 

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 BS EN 60077-1  together with specific subjects of wide interest and application, for example, temperature rise, dielectric properties, etc. 

Note: In the event of there being a difference in requirements between BS EN 60077-1 and a railway rolling stock relevant product standard, then the product standard requirements take precedence. 

Who is BS EN 60077-1- General service conditions and general rules for electric equipment for? 

BS EN 60077-1 on general service conditions and general rules for electric equipment for rolling stock is useful for: 

• Electric equipment manufacturers 
• Test centers  
• Regulatory authorities 

Why should you use BS EN 60077-1- General service conditions and general rules for electric equipment? 

Rolling stock all the vehicles with or without motors to which general service conditions and general rules are important to follow for proper functioning. 

BS EN 60077-1 guideline assists you with characteristics of the utilization category, rated voltages, rated voltages for electric equipment, rated currents for equipment, rated operational frequency, rated air pressure, product information, normal service conditions, constructional requirements, performance requirements, and test for general service conditions and general rules for electric equipment for rolling stock for railway applications. 

This assists you with proper general service conditions and general rules for electric equipment for rolling stock for railway applications that will ensure the maintenance and proper function of electric equipment for rolling stock. 

With compliance and obedience of BS EN 60077-1, you can harmonize as far as practicable all rules and requirements of a general nature applicable to electric equipment for rolling stock to obtain uniformity of requirements and tests throughout the corresponding range of equipment to avoid the need for testing to different standards. 

What’s changed since the last update? 

BS EN 60077-1:2017 supersedes IEC 60077-1 which is withdrawn. BS EN 60077-1:2017 has made some technical changes compared to IEC 60077-1. These includes: 

• Descriptions regarding insulation coordination, environmental conditions, and those of current return and protective bonding are deleted and replaced by references to IEC 62497-1, IEC 62498-1, and IEC 61991, except classes of air temperature, which are copied from Table 2 in IEC 62498-1:2010 
• Classification of equipment type is introduced 
• Temperature limits and temperature rise tests are reviewed 
• Example of lifetime calculation: Annex C (informative) is introduced
