Accessing the official PDF document is crucial for laboratories during two specific phases: Commissioning New Chambers
in electromagnetic shielded enclosures, such as anechoic chambers and RF-shielded rooms. ResearchGate Scope and Purpose
: The attenuation is calculated as the difference (in dB) between the reference signal and the signal measured through the shield. ResearchGate Key Technical Requirements
The shielding effectiveness (SE) is calculated in decibels (dB) using the following formula: en 50147-1 pdf
EN 50147-1 is a European standard titled "Anechoic chambers - Part 1: Shielding effectiveness" . Published by CENELEC (European Committee for Electrotechnical Standardization), this document specifies the precise methods used to measure the shielding performance of high-performance shielded enclosures and anechoic chambers.
Special attention is given to testing the integrity of doors, ventilation panels, and penetrations (power/signal cables), as these are common points of failure. How to Obtain the EN 50147-1 PDF
Anechoic chambers are essential environments for testing Electromagnetic Compatibility (EMC). To ensure these chambers isolate electronic equipment from outside interference, engineers rely on strict international standards. One of the foundational documents for verifying this isolation is the European standard . Accessing the official PDF document is crucial for
The difference between the reference reading and the shield reading determines the Shielding Effectiveness value at that specific frequency. 3. Critical Test Locations
It was a typical Monday morning for Emily, a young engineer working for a leading manufacturer of electromagnetic compatibility (EMC) testing equipment. She sat at her desk, sipping her coffee, and staring at her computer screen with a mixture of excitement and dread. Her task for the day was to ensure that their latest product, a high-frequency signal generator, complied with the European standard for EMC, specifically EN 50147-1.
Chamber shields rarely fail in the middle of solid steel panels. Leaks usually happen at joints, entries, and structural penetrations. EN 50147-1 requires thorough testing around these weak points: To ensure these chambers isolate electronic equipment from
Shielding performance degrades. Door fingers wear down, bolts loosen, and filters fail. Periodic testing ensures the chamber remains compliant.
This standard is harmonized under many EU directives, meaning compliance with it is often necessary for CE marking of high-voltage or EMC-sensitive equipment.
