: It is used to ensure that a newly constructed or modified chamber meets its specified attenuation requirements before it is used for product compliance testing. Gtem Cells Core Measurement Procedure
The standard, titled "Anechoic Chambers Part 1: Shield Attenuation Measurement," is a critical European regulation for validating the performance of electromagnetic shielding. It provides a standardized procedure to measure how effectively a shielded enclosure (such as a room or chamber) blocks electromagnetic interference (EMI). Core Objectives and Scope en 50147-1 pdf
Power and signal cable penetrations must be filtered properly to maintain the shield's integrity.
In conclusion, EN 50147-1 is a vital standard that ensures the electromagnetic compatibility of railway rolling stock. By understanding the requirements and significance of this standard, railway operators and manufacturers can ensure the safe and reliable operation of their equipment, reduce the risk of EMI-related incidents, and comply with European regulations. | Source | Standard Designation | Price (approx
Major global distributors of technical engineering standards. Summary of Benefits
Shield attenuation is calculated based on the difference between the signal received without the shield and the signal received with the shield in place, providing a quantitative measure of efficiency. Why Use the EN 50147-1 Standard? Core Objectives and Scope Power and signal cable
Remember: a chamber that fails EN 50147-1 validation is a liability, not an asset. It can produce false passes (due to external noise masking real emissions) or false failures (due to ambient signals entering during immunity tests). By mastering this standard, you protect the integrity of every EMC measurement you will ever make.
The reference level establishes the baseline measurement against which attenuation is calculated, typically involving a calibration measurement in an open, unobstructed environment.
EN 50147-1 applies to electrical and electronic equipment that is intended to be used in residential, commercial, and industrial environments. The standard covers a wide range of equipment, including:
