Comprehesive One-Stop - Railway ElectronicDevices Testing and Certification Service

Enhance Railway Traffic Safety and Operation Efficiency


It has been over 200 years since the first railway service began, and the technology is progressing rapidly day by day, the demand of safety is getting more and more important for passengers. Therefore, the combination of the railway traffic safety improvement and operational efficiency becomes a key issue for railway traffic service provider as well as for electronic equipment manufactures


When the train is operating, it has to face a vibratory condition all the time, and sometimes the voltage is not stable, either. Therefore, how to avoid these conditions to protect passengers’ safety is the most important thing. Providing efficient railway electronic devices which could adapt to different environment situations include altitude, humidity, impact, vibration, and temperature, etc will be one of the ways to keep passenger safe.


EN 50155 applies to any low voltage electronic equipment installed on rail vehicles and in railway applications. This requirement helps system integrators find devices that are certified for railway applications and they are tested thoroughly to deal with unique situations presented by the rail industry. 


EN50155 ensures that the electronic equipments used on rolling stock are thoroughly tested for situations including Critical Temperature Requirements of variances from extreme cold to extreme heat, Shock and Vibration Protection to validate to handle each bump and reoccurring vibration wherever it is installed.
