If you have searched for the term , you are likely looking to understand the technical specifications, download the official standard, or ensure your testing environment meets European norms. This article provides a comprehensive overview of EN 50147-1, its scope, its importance, and how to legitimately access the PDF version.
The provides detailed diagrams and specifications for:
The standard is a European technical specification focused on Anechoic Chambers , specifically regarding the measurement of shielding effectiveness .
Before the chamber walls are tested, a reference signal baseline must be established.
The increasing use of electronic systems in railway rolling stock has raised concerns about electromagnetic interference (EMI) and electromagnetic compatibility (EMC). EMI can cause malfunctions, errors, or even complete system failures, which can compromise the safety of passengers, staff, and the general public. To mitigate these risks, the European railway industry has adopted the EN 50147-1 standard, which provides a framework for ensuring EMC in railway rolling stock.
It ensures high-power immunity test signals generated inside the chamber do not leak out and violate local telecommunication regulations or interfere with nearby equipment. Key Test Methodologies in EN 50147-1
Search your institution or company’s standards portal for . If you only need the method (not the official text), many EMC test labs publish summaries in their work instructions — search "shielding attenuation measurement EN 50147-1" to find publicly available extracts.
If you are setting up or maintaining an EMC facility, let me know:

Over the next few hours, Emily worked tirelessly to modify the product's design, ensuring that it would pass the rigorous EMC testing required by the EN 50147-1 standard. With each revision, she felt a sense of satisfaction, knowing that her work would help ensure the safe and reliable operation of electronic devices across Europe.
As she began to dig into the standard, Emily realized she only had a printed copy of the document, which was over 20 pages long. She recalled that her colleague, Jack, had mentioned that there was a PDF version available online, which would make her life much easier. She quickly typed "EN 50147-1 pdf" into her web browser and hit enter.
EN 50147-1 is part of a multi-series standard developed by CENELEC (European Committee for Electrotechnical Standardization). The standard is officially titled:
If you are looking for the PDF, it is a copyrighted document usually available for purchase through official standards bodies rather than free public download. What is EN 50147-1?
The Shielding Effectiveness is calculated using the standard formula:
Use high-quality double-shielded cables and run fiber-optic links where possible. Dirty or bent fingerstocks on the chamber doors.
include PD CLC/TR 50484 (a technical report providing recommendations for shielded enclosures validated under the EN 50147 series) and international equivalents like GB/T 12190 (the Chinese national standard for electromagnetic shielding enclosure shielding effectiveness testing methods).
