What is EN 50155:2017?

EN50155:2017 is a technical standard that specifies the requirements for electronic equipment used on rolling stock in railway applications. It was developed by the European Committee for Electrotechnical Standardization (CENELEC) and provides specific guidelines for the design, construction, and testing of electronic systems used on trains.

Design and Construction Requirements

This standard mandates that electronic equipment used on trains must be designed and constructed to withstand the harsh operating conditions typically encountered in railway environments. This includes factors such as temperature extremes, humidity, vibration, mechanical shock, electromagnetic interference, and power supply variations.

Testing and Certification

In order to comply with EN50155:2017, electronic equipment must undergo rigorous testing to ensure that it meets all the specified requirements. These tests include temperature and humidity cycling, mechanical shock and vibration resistance, electrical insulation and discharge capability, and electromagnetic compatibility. The test results are reviewed by accredited certification bodies, who issue the necessary certificates to verify compliance.

Benefits and Significance of EN50155:2017

The implementation of EN50155:2017 brings several benefits to the railway industry. Firstly, it ensures the safety and reliability of electronic equipment used on trains, thus reducing the risk of malfunctions or failures that could potentially lead to accidents. Secondly, it promotes interoperability, as equipment complying with the standard can be easily integrated into existing railway systems. Lastly, it helps to establish a level playing field for manufacturers, as complying with the standard becomes a mandatory requirement for participating in the railway market.
