EN 50155 Endurance Testing of Control Electronics
The European standard EN 50155 sets forth stringent requirements and recommendations for the design, construction, installation, and maintenance of signaling and control systems used in railway operations. Among its many provisions, this standard is particularly focused on ensuring that electronic components within these systems are robust enough to withstand harsh environmental conditions and operational stresses. This service focuses specifically on the endurance testing of control electronics according to EN 50155.
Endurance testing ensures that the electronic components used in railway signaling and control systems can operate reliably over their entire expected lifecycle, which is often significantly longer than typical consumer products. The test parameters are designed to simulate real-world conditions such as temperature cycling, vibration, humidity, shock, and other environmental stressors that these electronics might encounter during deployment.
Before we delve into the specifics of what this testing entails, it’s important to understand why endurance testing is so critical for railway signaling and control systems. These systems are not just ordinary electronic devices; they are mission-critical components that can directly impact passenger safety, operational efficiency, and overall reliability of rail transportation networks.
In practice, EN 50155 compliance involves a series of tests aimed at assessing the durability and robustness of control electronics. These tests include but are not limited to:
- Temperature cycling from -40°C to +85°C
- Vibration tests to simulate transportation stress
- Humidity and altitude testing for long-term exposure scenarios
- Salt fog exposure to mimic coastal environments
- Shock testing at various levels of impact forces
The test specimens are subjected to these environmental conditions in a controlled laboratory setting, ensuring that the results accurately reflect real-world performance. This approach allows for early identification and rectification of any design or manufacturing defects that could compromise system reliability over time.
During endurance testing, we use specialized equipment tailored to replicate the stressors outlined by EN 50155. For instance, temperature cycling chambers can simulate rapid changes in ambient temperatures, while vibration tables recreate the mechanical stresses experienced during transit. These tests are not just about withstanding conditions; they are also designed to evaluate how well components maintain performance under these challenging circumstances.
The ultimate goal of this testing is to ensure that the control electronics meet stringent standards for safety and reliability throughout their operational lifecycle. Compliance with EN 50155 is often a requirement or recommendation by regulatory bodies, insurance companies, and railway operators, emphasizing its importance in the sector.
Compliance with EN 50155 ensures that the products used in railway signaling systems meet high standards of reliability and robustness. This service plays a crucial role in ensuring that manufacturers and suppliers deliver products that are not only reliable but also capable of withstanding the most challenging conditions faced by modern rail transport.

Quality and Reliability Assurance
The quality and reliability assurance (QRA) process is a cornerstone of our commitment to delivering services that meet the highest standards. In the context of EN 50155 endurance testing, QRA ensures that every aspect of the test, from specimen preparation to final reporting, adheres strictly to international best practices.
Our QRA process begins with meticulous planning and coordination, ensuring that all tests are conducted in accordance with the detailed requirements specified by EN 50155. This includes selecting appropriate environmental conditions for temperature cycling, humidity levels for salt fog exposure, and shock forces that accurately reflect real-world scenarios.
During specimen preparation, we ensure that each component is tested under controlled conditions to replicate as closely as possible the actual operating environment in which it will be used. This involves cleaning components, applying necessary coatings or treatments, and ensuring that all connections are secure and free from defects.
The testing process itself is highly regulated, with stringent protocols for monitoring and recording data at every stage. Our state-of-the-art laboratory equipment provides precise measurements of temperature, humidity, vibration levels, and other key parameters. This allows us to generate detailed reports that provide clear insights into the performance of each component under test.
Our QRA process also includes rigorous quality control measures during testing. This ensures that any anomalies or deviations from expected results are promptly identified and addressed. For instance, if a component fails to meet certain criteria after exposure to specific environmental conditions, our team of experts works closely with clients to identify the root cause and propose solutions.
The final phase of QRA involves thorough analysis of all test data and preparation of comprehensive reports. These reports are not only technical but also provide valuable insights into potential improvements for future designs or manufacturing processes. By sharing these findings, we help our clients maintain a competitive edge in the market while ensuring that their products continue to meet the highest standards of quality and reliability.
Our QRA process is supported by a team of experienced professionals who are thoroughly trained in EN 50155 requirements and best practices. This ensures that every test conducted at our laboratory adheres strictly to international standards, providing clients with confidence that their products will perform reliably under the most challenging conditions.
