What is EN 50168

Introduction

EN50168 is a technical standard that defines the requirements for electronic equipment used in railway applications. It focuses on the electromagnetic compatibility (EMC) and electrical safety of these devices. In this article, we will delve into the details of EN50168 and explore its importance in ensuring the safe and reliable operation of electronic equipment within the railway industry.

EMC Compliance

The first key aspect of EN50168 is the evaluation of EMC compliance. Electromagnetic interference (EMI) and radio frequency interference (RFI) can significantly impact the performance of electronic equipment. To achieve EMC compliance, manufacturers must ensure that their devices meet the required emission and immunity levels as specified by EN50168. This involves conducting rigorous tests to examine both conducted and radiated emissions, as well as susceptibility to external interferences.

Electrical Safety

Another critical element of EN50168 is the assurance of electrical safety. Railway environments can be harsh and challenging, with various operating conditions and potential hazards. EN50168 mandates that electronic equipment must conform to specific safety standards to mitigate risks such as electric shock, fire, and damage to other equipment. This includes compliance with regulations such as IEC 60950-1 for general safety and IEC 62368-1 for hazard-based safety engineering.

Application and Benefits

EN50168 is applicable to a wide range of electronic equipment used in railways, including control systems, signaling devices, power converters, and communication devices. By adhering to this standard, manufacturers and railway operators can ensure the seamless integration and interoperability of different equipment from multiple suppliers. This ultimately contributes to enhanced safety, improved reliability, and better overall performance of railway systems.

In conclusion, EN50168 plays a vital role in the railway industry by setting standards for the EMC compliance and electrical safety of electronic equipment. Its requirements help to minimize electromagnetic interference and ensure the protection of both passengers and the equipment itself. By embracing EN50168, manufacturers can demonstrate their commitment to quality and reliability, while railway operators can have confidence in the safety and performance of the electronic devices used within their networks.
