What is EN 50155:2012?

EN50155:2012 is a technical standard that specifies the requirements for electronic equipment used in railway applications. This standard sets out the necessary criteria to ensure the safety, reliability, and performance of electronic systems in railway environments. In this article, we will explore the main aspects of EN50155:2012 and its significance in the railway industry.

Requirements for Electronic Equipment

One of the main purposes of EN50155:2012 is to establish rigorous requirements for electronic equipment used in railway applications. These requirements cover a wide range of aspects, including temperature, humidity, shock, vibration, EMC (Electromagnetic Compatibility), and power supply. By complying with these requirements, manufacturers can ensure that their electronic devices can withstand the harsh conditions commonly found in railways, such as extreme temperatures, heavy vibrations, and high levels of electromagnetic interference.

Safety and Reliability Standards

Safety and reliability are two critical considerations in any railway system. EN50155:2012 addresses these concerns by setting specific standards for electronic devices. For example, it outlines requirements for fire behavior, electrical insulation, and protection against electric shock. These standards help to minimize the risk of accidents, fires, and electrical malfunctions on trains or at railway stations. Additionally, they ensure that the electronic equipment performs reliably over an extended period, without causing disruptions or failures in the operation of the railway system.

Testing and Certification

To ensure compliance with EN50155:2012, electronic equipment intended for use in railway applications must undergo rigorous testing and certification processes. These procedures involve subjecting the devices to various environmental conditions and performance tests. For instance, equipment may be tested for its ability to operate within specified temperature ranges, resist mechanical shocks, and maintain functionality in the presence of electromagnetic disturbances. Certification bodies assess whether a product meets all the requirements outlined in the standard and issues the necessary certification if it passes all tests successfully.

Conclusion

EN50155:2012 plays an essential role in ensuring the safety and reliability of electronic equipment used in railway applications. By establishing rigorous requirements, this technical standard helps to minimize the risks associated with operating electronic devices in harsh railway environments. Manufacturers can comply with these standards by designing and producing products that meet the specified criteria. Testing and certification processes help to verify that electronic equipment performs reliably and safely, providing confidence to railway operators and passengers alike.

In summary, EN50155:2012 represents a significant milestone in the development of reliable and safe electronic systems for the railway industry.
