What is EN 50155-2017?

EN 50155-2017 is a international standard for electronic equipment used on rolling stock in railways, which includes trains, trams, and other rail vehicles. It ensures that the electronic devices used in these vehicles are designed and manufactured to withstand the harsh conditions encountered during railway operations.

Importance of EN 50155-2017 Compliance

Compliance with EN 50155-2017 is crucial for the safe and reliable operation of electronic systems on rolling stock. The standard sets specific requirements for aspects such as temperature, humidity, shock, vibration, electromagnetic compatibility, and power supply range. By adhering to these requirements, manufacturers can guarantee that their products perform optimally in railway environments.

Benefits of EN 50155-2017 Compliance

There are several benefits to complying with EN 50155-2017:

Reliability: EN 50155-2017 ensures that electronic equipment can operate consistently and reliably under challenging conditions, reducing the risk of malfunctions or failures that could impact the safety and efficiency of rail services.

Safety: The standard's requirements help prevent accidents caused by faulty electronic systems, protecting both passengers and railway staff.

Durability: Devices compliant with EN 50155-2017 are designed to withstand extreme temperatures, vibrations, and other environmental factors commonly encountered in railway operations, leading to longer lifespans and lower maintenance costs.

Interoperability: Complying with this standard promotes interoperability between different equipment brands and makes it easier to integrate new technologies into existing railway systems.

Complying with EN 50155-2017

To ensure compliance with EN 50155-2017, manufacturers need to follow specific design and testing procedures. These may include:

Component Selection: Choosing electronic components that meet the standard's requirements for temperature range, shock resistance, and other relevant parameters.

Product Design: Incorporating features such as thermal management, mechanical robustness, and protection against moisture to withstand harsh environments.

Testing and Certification: Conducting rigorous testing to verify that the product meets all the requirements outlined in EN 50155-2017. Certification by accredited bodies may be necessary to demonstrate compliance.

Documentation: Maintaining detailed documentation of the design, manufacturing processes, and test results to prove compliance during audits or inspections.

In conclusion, EN 50155-2017 is a vital standard that ensures electronic devices on rolling stock meet stringent requirements for reliability, safety, durability, and interoperability. Compliance with this standard provides numerous benefits for manufacturers, passengers, and railway operators alike.
